The article is devoted to the study of state control over the technical condition of vehicles in Ukraine. The analysis of road accidents caused by operation of technically defective vehicles is carried out. It is stated that the fleet of vehicles in Ukraine is dynamically increasing, and the average age of cars is 22.4 years, which leads to the introduction of effective mechanisms to control their technical condition. It is determined that the subject of state control of the technical condition of vehicles is the state represented by the National Police of Ukraine. The basic principles of state control in the field of road safety are described. It is proved that the function of state control over the technical condition of vehicles by the National Police of Ukraine is implemented through inspections of the subjects of mandatory technical control and control of the technical condition of vehicles during their operation. An analysis of the administrative and jurisdictional powers of the National Police of Ukraine units in relation to persons who drive technically defective vehicles and economic entities authorized to carry out mandatory technical control. An effective mechanism for police control of the technical condition of vehicles during their operation, the procedure for issuing instructions, accounting and lifting the ban on the operation of vehicles by the Unified Information System of the Ministry of Internal Affairs of Ukraine. The necessity of introducing a ban on the operation of a vehicle by a police officer as a measure to ensure proceedings in cases of administrative offenses and the establishment of administrative liability for violations by drivers of the ban on the operation of vehicles, issued by the competent authorities.

Purpose. The study aims to establish positive changes after the introduction of traffic accident monitoring systems implemented by government agencies in China, India, Germany, the United States, the United Kingdom, Finland, Beijing and Sweden. Methods. The research was carried out in stages, based on the logical presentation of the material. The following methods were implemented in the study: direct observation, comparison and analysis of the content and the form of advanced traffic accident monitoring systems. Results. The study of international best practices and experiments about the implementation of various options for traffic accident monitoring systems gave preference to an intelligent system. A study conducted in the United States, India and Portugal shows the effectiveness of different approaches to use mobile applications on smartphones to transmit reliable information to the traffic accident registration system. Accident data collection should be standardized and structured, and police officers should benefit from the statistical reports they complete for each traffic accident.
