Driving under the influence: An analysis of second-time offenders and intervention success, Turkey sample

Objectives Driving under the influence (DUI) of alcohol is a major public health issue that results in significant mortality, morbidity, and economic costs. Despite various penalties and interventions, DUI remains prevalent. This study examines the demographic characteristics, educational status, and involvement in motor vehicle accidents of second-time DUI offenders, aiming to identify factors influencing the success of educational interventions. Methods Between 2018 and 2023, 151 individuals whose driver’s licenses were suspended for a second DUI offense participated in this study. All participants applied to the Adıyaman Provincial Health Directorate, located in the southeast region of Turkey, to regain their licenses. Data were collected from application documents and digital records during and after the educational program, which included identity information, demographic characteristics, reasons for alcohol consumption, license duration, education level, educational success, frequency of alcohol use, and behavior under the influence. Penalties and traffic accidents in the last 5 years were also recorded. Results Participants with a high school education and above had a significantly higher success rate in the educational program (P = .03). Those without penalties (P = .001) and those not involved in traffic accidents (P = .006) also showed higher success rates. Conclusion Despite its limitations, this study shows that second-time DUI offenders who have previous traffic tickets or accidents are less likely to succeed in educational interventions. These findings suggest the need for tailored training programs, extended durations, and personalized evaluations to improve outcomes for these high-risk groups. Future research should explore prospective studies to confirm these results and guide intervention strategies.

Driving under the influence of cannabis: A 5-year retrospective Italian study

IntroductionCannabis consumption is associated with driving impairment and increased crash risk, endangering road safety. Toxicological analyses play a fundamental role in detecting a recent consumption of psychoactive substances. The aim of this study was to examine the concentration of cannabinoids in blood samples of driving-under-the-influence (DUI) offenders in order to investigate whether delayed sample collection affects the toxicological assessment of the offenders. Materials and MethodsAn observational retrospective study was performed using anonymized toxicological data referring to cannabis-related DUI offenders involved in road traffic accidents (RTA) or apprehended by the police from 1 January 2017–31 December 2021 archived at Legal Medicine and Toxicology Department of the University Hospital of Padova, Italy. ResultsIn a total sample of 318 drivers, 143 blood samples tested positive for tetrahydrocannabinol (THC) and metabolites 11-hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC) and 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), and 173 blood samples were positive for THC-COOH with THC negative. In the first group, the mean concentrations of THC and THC-COOH were 4.05 ng/mL and 28.29 ng/mL, respectively. In THC-negative cases, the mean THC-COOH concentration was 7.3 ng/mL. The time elapsed between the event and sample collection varied from 15 min to 7 h (mean 2 h 29 min). The average estimated time elapsed after consumption of cannabinoids was 3 h 7 min (Model I) and 2 h 36 min (Model II). ConclusionsThe present research discussed the main difficulties in the toxicological evaluation of drivers under the influence of Cannabis. Issues related to the time between RTA and sample collection, the laws and legal limits in force in various Countries were presented

Drunk driving policies and breath test refusal in Taiwan

Objective Driving under the influence (DUI) is one of the major causes of traffic crashes in Taiwan, leading to huge medical expenditures and human capital loss. Although the authorities have enacted several policies to reduce drunk driving, most penalties are based on drunk drivers’ alcohol levels. According to Taiwan regulations, drivers could pay a fine to refuse the breath test if they are not involved in a traffic collision, and there is no clear evidence showing that they are DUI. Therefore, increased sanctions for DUI may lead to increased breath test refusals. If breath tests for drunk driving could be refused with little or no punishments for drivers, then the detection of behavioral impairment would weaken, and the deterrent effect of DUI punishment would be limited. Method This research uses interrupted time-series analysis (ITSA) to examine how policy reforms from 2007 to 2020 affected driver’s breath refusal rate in Taiwan. Results We find that said reforms that exclusively increase the punishment of DUI offenders did raise the refusal rate immediately and persistently, suggesting that more drunk drivers would refuse a breath test to avoid more severe DUI punishment. Policy reforms that increase penalties for drivers refusing to take breath tests may instantly lower the refusal rate, but the long-term effects are contingent upon the DUI punishment. Conclusions It appears that drunk drivers could still decide on breath test refusal to avoid a DUI conviction if the punishment for refusing the test is less severe than that for DUI. Aggravating penalties for refusing breath tests would decrease the refusal rate and help reinforce DUI’s deterrent effect.

Postintervention reoffense in DUI repeat offenders receiving alcohol treatment as a diversion intervention: A 2-year follow-up study

PurposeAlcohol use problems are prevalent among recidivists of driving under the influence of alcohol (DUI). This 2-year postintervention follow-up study explored the preventive effects of 12- or 6-month alcohol treatment in relation to reoffense among repeat DUI offenders who participated in a community-based joint legal–medical intervention program. MethodsA total of 259 repeat DUI offenders with alcohol use problems were referred from a Prosecutors’ Office to a psychiatric hospital to receive alcohol treatment. We divided these participants into two groups on the basis of treatment duration (6- and 12-month groups) and collected their official DUI offense records for 2 years after the intervention. A Cox proportional hazards model was used to examine the hazard ratio of each treatment duration in relation to reoffense. The reoffense rates were compared with a group of DUI offenders (n = 4097) who did not participate in the intervention program (i.e., a nonintervention group). ResultsThe baseline characteristics were similar between the two treatment groups. The 2-year reoffense rates for the 12-month treatment, 6-month treatment, and nonintervention groups were 12%, 19%, and 21%, respectively. The hazard ratio for reoffense was lower for the 12-month group than for the 6-month group (hazard ratio: 0.45; 95% confidence interval: 0.21–0.96). Survival analysis revealed that compared with the non-intervention group, reoffense was significantly reduced in the 12-month group but not in the 6-month group. ConclusionThe 12-month joint legal–medical intervention program for alcohol treatment yielded superior outcomes to the corresponding 6-month program in terms of preventing DUI reoffense for 2 years postintervention. This research is, however, subject to the limitation that we lacked the information of factors that might affect the reoffense risk, such as motivation level, readiness to change, personality traits, and familial support.

Driving license regranting: Hair EtG, serum CDT, and the role of sociodemographic and medicolegal variables.

Driving under the influence (DUI) of alcohol is a road safety problem. Driving license regranting is based on the evaluation of medicolegal and toxicological variables that may include serum carbohydrate-deficient transferrin (CDT) and hair ethyl glucuronide (hEtG). The aim of the study was to compare the diagnostic performance of CDT and hEtG in a population of DUI offenders. Other factors potentially associated with heavy alcohol use were explored. The population included DUI offenders examined during the period of January 1, 2019, through June 30, 2022. Sociodemographic, medicolegal, and toxicological variables were collected. CDT in serum and EtG in head hair were determined in all subjects. Excessive alcohol intake (hEtG ≥30 pg/mg) was considered cause for unfitness to drive. Cohen's kappa coefficient was calculated. Descriptive analyses were performed using chi-square and Mann-Whitney tests. Variables significantly different between the groups were included in a multivariate binary logistic regression model. The sample encompassed 838 subjects (case group: 179, comparison group: 689). CDT exhibited poor agreement (κ = 0.053) with hEtG as the reference test. Lower education, age at DUI, heavy smoking, and GGT levels associated with heavy alcohol consumption differentiated the two groups. For DUI offenders, the use of CDT to assess heavy alcohol consumption is limited, possibly due to the time-window assessed, the time required for normalization, and the different amount of ethanol needed to reach higher CDT levels, in comparison to hEtG; thus, hEtG assessment is strongly recommended for this population. Heavy smoking, GGT, education, and age could be related to heavy alcohol consumption and higher risk of DUI.

Do Victim Impact Panels Have Sustained Effects on DUI Recidivism?

This study examines whether Victim Impact Panels reduce DUI recidivism 5 to 8 years postsentence. Original 2-year data on 410 DUI offenders who attended a Victim Impact Panel and 373 DUI offenders from the same court system who did not attend a Victim Impact Panel indicated slight recidivism reduction effects. Logistic regression results at the 5-year period reveal that not attending a Victim Impact panel increases the odds of another DUI by a factor of 1.5 with an upper 95% confidence odds level of 2.2. At the 8-year mark, non-VIP participants were 1.8 times more likely to record another DUI with an upper 95% confidence odds level of 2.6. Offenders with a prior DUI who attended a Victim Impact Panel had significantly lower recidivism rates after 8 years relative to non-attendees. Prior research suggested that males in the 26–35-year age group benefitted more from Victim Impact Panel participation. These data indicate that the effects of age are relatively uniform across male age groups. Overall, these recidivism results indicate that the emotional messages communicated by victims to DUI offenders might carry sustained effects.

Reward Deficiency Syndrome (RDS): A Cytoarchitectural Common Neurobiological Trait of All Addictions

Alcohol and other substance use disorders share comorbidity with other RDS disorders, i.e., a reduction in dopamine signaling within the reward pathway. RDS is a term that connects addictive, obsessive, compulsive, and impulsive behavioral disorders. An estimated 2 million individuals in the United States have opioid use disorder related to prescription opioids. It is estimated that the overall cost of the illegal and legally prescribed opioid crisis exceeds one trillion dollars. Opioid Replacement Therapy is the most common treatment for addictions and other RDS disorders. Even after repeated relapses, patients are repeatedly prescribed the same opioid replacement treatments. A recent JAMA report indicates that non-opioid treatments fare better than chronic opioid treatments. Research demonstrates that over 50 percent of all suicides are related to alcohol or other drug use. In addition to effective fellowship programs and spirituality acceptance, nutrigenomic therapies (e.g., KB220Z) optimize gene expression, rebalance neurotransmitters, and restore neurotransmitter functional connectivity. KB220Z was shown to increase functional connectivity across specific brain regions involved in dopaminergic function. KB220/Z significantly reduces RDS behavioral disorders and relapse in human DUI offenders. Taking a Genetic Addiction Risk Severity (GARS) test combined with a the KB220Z semi-customized nutrigenomic supplement effectively restores dopamine homeostasis (WC 199).

Cigarette Smoking as a Predictor of Male DUI Recidivism.

This study aimed to investigate the predictors of recidivism in first-time driving under the influence (DUI) offenders, analyzing variables derived from medico-legal and toxicological examinations. The research was structured as a comparative study for the period 2012–2019. DUI offenders with a blood alcohol concentration >0.5 were included in the study. The case group consisted of recidivist offenders, while the comparison group consisted of first-time offenders. Personal data, socioeconomics, and parameters linked to the DUI were compared between the two groups. Significance was determined by chi-square and Mann–Whitney tests. To prevent confounding effects, multivariate binary logistic regression analysis was performed. Our sample encompassed 1678 subjects (196 in the case group, 1482 in the comparison group). Gender, driving license category, education, and tobacco use resulted in significant differences between the groups. In a model including age at DUI, education, and smoking habit as independent variables, higher educational levels (high school, bachelor’s) and older age protected against recidivism, whereas smoking >20 cigarettes/day was an independent risk factor for recidivism. Recidivist offenders have specific characteristics indicating different therapeutic programs and carefulness in driving license regranting. A higher tobacco consumption in recidivists suggests that the use of this substance could influence the risk of DUI for reasons that will need to be explored.

The effectiveness of alcohol monitoring as a treatment for driving-while-intoxicated (DWI) offenders: A literature review and synthesis

Objective The advent of continuous, passive, transdermal alcohol-monitoring devices and portable breath-testing devices with cameras provides a more efficient and reliable method for controlling the impaired driving of driving-under-the-influence (DUI) offenders. The objective of this study was to conduct a comprehensive literature review and synthesis of the strategies, the obstacles and the effectiveness of implementing alcohol monitoring as a component of treatment for DUI offenders. Method A formalized review of the existing literature was conducted including both peer-reviewed and gray literature resources. Professional association websites were also searched in an effort to seek information on the effectiveness or ineffectiveness of alcohol monitoring as a strategy to treat DUI offenders. The review was guided by pre-defined inclusion/exclusion criteria that identified the scope and key terms to use when searching. Results The literature shows that there is promising to strong evidence that alcohol monitoring is an effective component in treating DUI offenders and reducing recidivism rates. Alcohol ignition interlocks had the most studies (71 of the 131 articles identified in this review) and research shows that recidivism rates can be reduced by 50 to 90 percent for offenders while the interlock is installed. However, most ignition interlock studies are subject to sampling issues where participants are not randomly assigned to experimental and comparison groups. There is also evidence that alcohol monitoring is a key measure in 24/7 Sobriety Programs, in enforcing abstinence, and in overall alcohol treatment programs. Conclusions Transdermal monitoring is generally effective in deterring offenders from drinking alcohol. Offenders who drink or are otherwise noncompliant are likely to be identified. Transdermal monitoring helps enforce abstinence, which in turn helps offenders quit drinking and go into a recovery stage, potentially creating long-term safety benefits for the community. Continuous transdermal monitoring is a more effective means of monitoring drinking than other techniques and technologies (e.g., self-report, periodic or random breath tests, patches, or urinalysis).

I Did It, But…: Exploring DUI Offender Deviance Rationalization in the Digital Age

ABSTRACT The dangers associated with alcohol-impaired driving are well documented, most recently stabilizing at still problematic levels around 2010. Recent estimates indicate over 1 million annual DUI arrests. Researchers have primarily adopted quantitative approaches to identify common predictors of impaired driving. Few studies have systematically examined this group using qualitative data, specifically how they process the heavily stigmatized arrests and none have specifically examined these processes in online spaces. To fill this gap, a qualitative content analysis was conducted on over 600 DUI narratives from reddit. This study documents the stigmatizing effects of a DUI arrest and explores the utility of accounts and techniques of neutralization in negotiating impaired driving on a digital stage. Analyses suggest offenders utilize multiple strategies to deflect full culpability for their arrest, performing impression management through excuses, justifications, and techniques of neutralization to minimize responsibility for driving impaired, the reason for police contact, failed field sobriety tests, or illegal blood alcohol concentrations. These insights provide additional support for the utility of easily accessible online data as a fruitful arena for analyses of contemporary social problems.

Evaluating the Computerized Assessment and Referral System (CARS) Screener: Sensitivity and Specificity as a Screening Tool for Mental Health Disorders among DUI Offenders

Background/Purpose: A growing body of evidence suggests that people who are arrested for driving under the influence (DUI) of alcohol are more likely to screen positive for psychiatric disorders than the general population. Additionally, psychiatric comorbidity has been shown to increase vulnerability to criminal re-offense. However, DUI programs face many barriers to screening for psychiatric disorders. This paper evaluates the sensitivity and specificity of a screening tool developed for these programs, the Computerized Assessment and Referral System (CARS) Screener. Methods: We used data from 381 DUI offenders in Massachusetts, as well as a secondary data source, the National Comorbidity Survey-Replication (NCS-R: N = 9,282) to examine the accuracy of the CARS Screener when compared to full assessment. Results: Based on both sets of analyses, we found that the CARS Screener offers a sensitive and specific method to screen for many psychiatric disorders. Specifically, the CARS Screener has a high sensitivity and specificity for bipolar disorder, intermittent explosive disorder, depressive disorders, generalized anxiety disorder, alcohol and drug use disorders, gambling disorder, post-traumatic stress disorder, panic attacks, and social phobia. Conclusion: The CARS Screener appears to be an effective tool that will help DUI programs better understand and address the mental health issues facing their clients.

An Examination of How DUI-Child Endangerment Laws Are Used in Court

Each year, about 200 children aged 14 years old (y/o) or less die and another 4,000 are physically injured while being driven by an adult that has been drinking (aged 21 y/o or more). Concerned by this phenomenon, there are a growing number of States implementing Driving Under the Influence – Child Endangerment (DUI-CE) laws to prevent adults from driving under the influence with children. These laws however, have failed to reduce the rates of DUI-CE injuries and fatalities. It has been hypothesized that such a failure occurs, at least in part, because these laws are being pled-down in courts, this study examines this hypothesis. We analyzed DUI-CE related court information collected by court monitors available in the Court Monitoring Database (CMD) provided by the Mothers Against Drunk Driving (MADD). Despite investigating data that included only DUI offenders who were driving with at least one child passenger at the time of the arrest, only 10% of those charged with a DUI felony and 11% of those charged with a misdemeanor were also found guilty of a DUI-CE violation. These findings support the hypothesis that DUI-CE offenses are being pled down in court and probably contribute to the ineffectiveness of DUI-CE laws. Unfortunately, data limitations preclude any decisive conclusions. Future research should focus on increasing our understanding of the DUI-CE problem and understanding why DUI-CE laws are not working toward the goal of deterring and punishing those who endanger the lives of children.

Driving license regranting in DUI subjects: Road accident variables and predictive factors of substance use disorder.

A comparative case study (2017-2020) was conducted to identify demographic, social, medico-legal, and toxicological variables associated with non-fatal accidents in driving under the influence (DUI) subjects. A second aim was to identify the factors predictive of substance use disorders among subjects. Drivers charged with alcohol DUI (blood alcohol concentration (BAC) > 0.5) and/or psychoactive substance DUI were included; cases included those involved in an accident while intoxicated, and the comparison group included DUI offenders negative for road accident involvement. Significance was determined by chi-square and Mann-Whitney tests. To prevent confounding effects, a multivariate binary logistic regression analysis was performed. Our sample encompassed 882 subjects (381 in the case group and 501 in the comparison group). Parameters such as psychoactive substances and BAC at the time of the road crash/DUI and the day of the week, when subjects were involved in the road accident or found DUI, resulted in significant differences (p < 0.01) between groups. The model's independent variables of BAC > 1.5 g/L (p = 0.013), BAC > 2.5 g/L (p < 0.001), and concurrent alcohol and psychoactive substance use (p < 0.001) were independent risk factors for an accident. Smoking >20 cigarettes/day was an independent risk factor for unfitness to drive (p < 0.01). Unfitness to drive was based primarily on ethyl glucuronide levels >30 pg/mg. Our results suggest a detailed assessment of DUI subjects with variables associated with accidents (BAC > 1.5 g/L and concurrent intake of psychoactive substances). Hair analysis, including ethylglucuronide (EtG) concentration, should be always performed. Based on our results, nicotine use should be investigated in cases of driving license regranting.

Conviction celerity and intervention compliance as predictors of DUI recidivism: a mediation model of deterrence among Kentucky DUI offenders

Approximately one-third of DUI offenders in the United States are repeat offenders. The criminal justice system has used both deterrence-based and rehabilitation approaches to prevent DUI recidivism. However, existing studies have not examined deterrence and rehabilitation as they relate to DUI recidivism in a single model. The goal of this study is to simultaneously examine the effects of an established deterrence-related measure (conviction celerity) and a rehabilitation outcome (intervention compliance) on DUI recidivism, specifically whether intervention compliance mediates the relationship between conviction celerity and DUI recidivism. Utilizing a statewide sample of DUI offenders (N = 6,936), a mediation model was tested to examine intervention compliance as a potential mediator between conviction celerity and recidivism, controlling for known correlates of DUI recidivism. The mediation model was unsupported, but compliance was significantly related to DUI recidivism. Several covariates were also related to compliance and recidivism. Findings suggest that compliance and other factors may increase the risk of DUI recidivism among certain populations. Results demonstrate the need for the criminal justice system and behavioral health providers to thoroughly assess DUI offenders to identify those at higher risk of recidivism, while emphasizing offenders’ treatment needs, treatment accessibility, and treatment retention in order to decrease DUI recidivism.

Changes in Alcohol Use and Drinking and Driving Outcomes From Before Arrest for Driving Under the Influence to After Interlock Removal.

Half of the offenders convicted of impaired driving in the United States are sentenced to install alcohol ignition interlock devices (IIDs), which prevent them from starting their vehicles if they have been drinking. No research has yet explored offenders' patterns of alcohol consumption and driving under the influence of alcohol (DUI) from the time before the arrest to the time period after the IID is installed. This study aims to fill that gap in knowledge. Using the Timeline Follow-back interview procedure, we assessed the daily drinking of 153 convicted DUI offenders' self-reported total alcohol consumption and rates of self-reported driving after drinking over 4 phases: before DUI arrest, between arrest and IID installation, during the phase on the interlock, and after the interlock is removed. Because information about behaviors in each period was not available for every participant, comparisons were made using paired-sample contrasts. Compared with before the arrest, total alcohol use decreased by 50% in the 4-month phase following arrest and before IID installation, though it did not change much afterward. The frequency of drinking and driving decreased sharply after the arrest (-82%), with further decrease upon installation of the interlock (-58%, p=0.05). The frequency of drinking and driving after the IID was removed returned to preinstallation drinking and driving status (+58%, p=0.01). Participants made significant adjustments to their drinking behavior by adhering to the traditional DUI driving restrictions in the postarrest phase. Although installation of an IID was not associated with a significant change in drinking, it further reduced the frequency of drinking and driving. Evaluations of the IID experience should take into account information on an individual's drinking and DUI behaviors not only before the IID was installed, but before the individual was arrested.

Does Prison Deter Drunk-Drivers?

To examine the specific deterrent effect of prison on driving under the influence of alcohol (DUI) recidivism. The study outcomes were the probabilities of DUI re-offending over 6 months, 24 months and 5 years ‘free time’ (i.e. time not spent in custody). The comparison group consisted of offenders convicted of DUI offending who received a suspended sentence of imprisonment. The effect of imprisonment was examined in a series of 2SLS models; employing an extensive set of controls (age, gender, race, remoteness of residence, socioeconomic status, legal representation, number of concurrent offences, DUI blood alcohol range, number of prior court appearances, prior penalties) and variation in the judicial proclivity to imprison convicted drunk drive offenders as an instrument to identify the effect of prison on DUI re-offending. Our free-time analyses reveal no evidence that imprisonment reduces the risk of DUI recidivism. Separate analyses for first-time DUI offenders revealed a slight (5%) reduction in re-offending over 24 months free time but no effect over 5 years. We conclude that the funds currently spent on imprisoning DUI offenders could be more fruitfully be invested in measures that show more promise in reducing DUI recidivism.

A Latent Class Analysis of DUI Offender Motivation and Awareness as Predictors of Performance While on Alcohol Ignition Interlocks

ABSTRACT Introduction . Alcohol ignition interlock devices (IID) reduce rates of drinking and driving. The interlock offers an opportune time for tailoring targeted interventions to develop habits to separate drinking from driving among this high-risk population. This study identified different types of IID users upon whom targeted interventions could be developed. Methods Participants (N = 114) were assessed at IID installation and again six months later. Latent class analysis (LCA) was conducted using drinking environment, drinking motivation, social support, drug use, and problem drinking behaviors as indicators. Multivariate regression analyses were conducted comparing latent class assignment with impaired driving attempts. Results LCA supported a 4-class model where 14.8% of participants fell into the low use/high awareness class; 30.6% fell into the heavy use/high awareness class; 30.6% fell into the mixed use/high awareness class; and 24.0% fell into the moderate use/low awareness class. Drivers in the moderate use/low awareness condition had increased early morning BAC lockouts. Conclusions These typologies demonstrate important differences within high risk drivers. Indeed, drivers who fell into the moderate use/low awareness class may not have considered their alcohol-related behaviors problematic. This information could lend itself to the development of targeted interventions to address subgroups of drinking drivers.

Driver experiences with the alcohol ignition interlock: Comparing successful and poor performers

Objectives The purpose of this investigation was to compare the drinking patterns and experiences (both positive and negative) among DUI offenders who had installed an ignition interlock. The association between those experiences and interlock performance as measured by the number of times they had a lockout, was also assessed. Methods Over 300 DUI offenders who installed an interlock in the State of Florida were recruited and completed an on-line survey at the beginning and end of their interlock restriction. A record of the interlock performance data from each was downloaded and used to determine how many lockouts they experienced during their interlock restriction period. Offenders were defined into two groups; successful cases (having 0 or 1 lockout) or poor performers (have 2 or more lockouts). Chi-square and binary regressions were used to assess differences between groups. Results Poor performers reported significantly more drinking and were more likely to drink in a context of emotional comfort, yet they were more likely to report positive experiences with the interlock, especially as to its ability to remind them to avoid another DUI by reducing their drinking and driving. No difference was found between these two groups for the interlock’s ability to reduce drinking. Conclusions People with a more serious drinking pattern and who may be most at risk for recidivating may be more inclined to recognize the potential benefits of the interlock as a DUI preventive countermeasure. More research is needed to identify and influence high risk DUI offenders while on the interlock to increase its effectiveness once the interlock is removed.
