How often should a car over 15 years old be inspected?
1 Answers
Vehicles over 15 years old require inspection every six months. Relevant details are as follows: 1. Inspection regulations for small passenger cars. Vehicles under 6 years are exempt from inspection but must obtain a free inspection exemption certificate every 2 years (dual-certificate integration). Vehicles over 6 years require annual inspection. 2. Vehicle annual inspection refers to mandatory testing for all vehicles with official license plates and registration certificates, equivalent to an annual physical examination according to the "Technical Conditions for Motor Vehicle Operation Safety". Additional information: 1. The inspection includes exhaust emission testing (checking oxygen sensors and catalytic converters). Their optimal operating temperature is 400-800°C, so warming up the vehicle in the inspection area beforehand can increase the pass rate. 2. Before the inspection, owners should clean the vehicle body, engine compartment, and chassis in advance to facilitate the inspection process and improve the chances of passing.
