With the development of social economy, the possibility of road failures and accidents is also increasing. In order to ensure the normal operation of road traffic, certain limitations are imposed on the service life of wreckers. In the past, any type of vehicle that was operated would be forcibly scrapped within fifteen years. From small and miniature taxis to medium-sized passenger vehicles, the number of years of scrapping will range from 8 to 15 years. Recently, the latest regulations on the service life of wreckers have been made. Except for the compulsory retirement conditions for mileage and age, if the vehicle fails to pass the three vehicle safety technical inspection periods after the expiry of the test period, it is not eligible for inspection by the motor vehicle. The signs will also face forced scrapping. Compared with the old rules, the new rules have, to a certain extent, widened the service life of wreckers.
