First, the performance of headlights is not up to standard: According to statistics, the most common reason for the unqualified annual inspection of general vehicles is that headlights are not up to standard. The lack of brightness and transparency of car lamps is due to the aging of the circuit, and the vehicle will have no electricity after a long time of use. At the same time, the police reminded that if the owner replaces the headlights with non-original accessories, the materials used in the headlights are poor, which may lead to dimming of the lights after a period of use. It may also be that the lampshade is flooded when washing the car.

Second, vehicle braking failure: vehicle braking failure is also one of the main reasons why vehicles cannot pass the annual inspection. There are many factors that cause brake failure, generally due to brake pad wear. Driving habits and other reasons may also lead to vehicle braking failure. Judging from the feedback from the inspection station, the braking problem of the vehicle is often carefully looked at during the annual inspection. In addition to normal braking, manual braking is also the focus of inspection. However, the usual maintenance of the handbrake is easily overlooked by ordinary car owners, and often the negligence of operation once or twice when the vehicle is started will cause great wear and tear to the handbrake.

Third, the automobile exhaust emission is not up to standard: the unqualified exhaust detection is also one of the reasons why the owner often fails the annual inspection. Generally speaking, there will be unqualified automobile exhaust emissions, and most of them are older cars. There are many factors that cause automobile exhaust emissions to exceed the standard. The only way to improve and avoid this situation is for car owners to keep good driving habits as much as possible and do regular maintenance instead of adding private oil.

Fourth, the vehicle traffic violation record has not been processed: this is also the most easily overlooked problem. Car owners all know that traffic safety violations and traffic accidents involved in vehicles must be dealt with before the annual inspection. At the same time, each motor vehicle inspection station generally has a place where traffic violations are inquired, which is convenient for the owner to inquire before the inspection. However, this problem was forgotten by the owner in the annual review of the usual car inspection station.

5. The appearance of the car body does not match the driving license: Now many car owners like to modify the car or use the car body for advertising. Before and after modification, bumpers, pedals around the car body, tail fins, exhaust pipes, tires, personalized wheels, etc. These changes in the appearance of the car body are generally unable to pass the annual inspection unless they are made to the vehicle management office. At the same time, many riders like to paint their cars or install decorative car stickers. If the car sticker area exceeds 30%, it will also bring unnecessary trouble to the owner during the annual inspection.
