With the advent of the risk society and the abolition of the labor education system in China, many misdemeanors have been prescribed in Criminal Code, and the structure of crimes and penalty changed greatly. A series of negative consequences have been triggered. The most typical phenomenon is the behavior of drunk driving is prescribed in the criminal code as the crime. Although this new provision has achieved the unity of social and legal effect, it also brings a series of problems. Firstly, at the legislative level, so many new misdemeanors are prescribed in the criminal code, which will expand the range of crimes and shake the existing criminal law system. Secondly, at the judicial level, many judicial resources are occupied. Four sets of data are obtained by actual investigation. These data indicated that the number of misdemeanor in China has increased sharply every year, and a large amount ofj udicial resources have been squeezed, which seriously affects judicial efficiency. Thirdly, at the social level, once the offender is labeled as «criminal», it means that the offender will be difficult to return to the society, and the recidivism rate will be greatly added. On the other hand, the «crime label» will have a «chain negative effect» on the offender ’s family and family members. In order to effectively solve the negative consequences of the misdemeanor represented by the crime of drunk driving, the corresponding suggestions are proposed as follow: felony and misdemeanors should be punished differently, the balance of criminalization and non-criminalization should be realized, and the crimes should be controlled within the reasonable range. The system of extermination of the criminal record should be constructed in order to eliminate negative consequences caused and to achieve the good operation of law.
