[McCorey]

Under normal conditions, a car travels an average of 60 kilometers per hour. According to current traffic regulations, the inspection requirements for household vehicles are as follows: Within six years from the date of initial registration on the driving license, the license plate on the vehicle is exempt from inspection, but it must be reviewed every two years. For vehicles over six years old, inspection is required annually, and for those over fifteen years old, inspection is required every six months. As long as the inspection is passed, the vehicle can be driven normally. Annual inspection of a car (or vehicle) refers to the yearly inspection of vehicles that have obtained official license plates and driving licenses, conducted in accordance with the safety technical conditions for motor vehicle operation. The purpose is to check the main technical conditions of the car, urge and strengthen the maintenance of the car, ensure that the car is always in good condition, and guarantee the safety of driving.
