The expansion of the global supply chain has introduced a multitude of challenges, particularly in road freight transportation. These include extended lead times, high operational expenses, and limited end-to-end visibility. Modern technology must be included in the freight industry to streamline operations and maintain competitiveness. The freight transportation industry is poised for a shift driven by the Internet of Things. The Internet of Things delivers real-time tracking, predictive maintenance, and enhanced security which ushers in a new era for the road transportation industry. Adopting the internet of things will guarantee long-term competitive advantage and future success in a road freight sector. A skills gap remains an obstacle to the successful implementation of the Internet of Things. There has been limited research conducted on the effect of the Internet of Things in the Oman road freight industry. The goal of this study was to document the implementation of Internet of Things and its effect on operational effectiveness through perceived useful in Oman road freight industry. This study used a positivist research philosophy associated with quantitative research. Data was gathered from the five biggest companies in the road freight industry in Oman. A pilot test was conducted to assess the reliability of the research instrument used. A convenience sampling technique was administered to collect data from respondents. A total of 203 structured questions were distributed on-line to workers in road freight sector in Oman. A structural equation modelling was used to analyze the quantitative data in the study. Results show that the adoption of IoT in the road freight sector is a continuous trend. Further findings show that the relationship between IoT and operational effectiveness is partially mediated by perceived usefulness. Improved operational effectiveness is the primary impact of IoT on the road freight sector. Managers are informed that smart sensor technologies can be used with the IoT to allow asset visibility and save operational costs. Future research may explore the financial gains attained through the utilization of IoT within Oman road freight industry.
