How many times should a vehicle over 15 years old be inspected per year?

[ChloeDella]

Vehicles over 15 years old should be inspected twice a year. According to the regulations of the Road Traffic Safety Law Implementation Regulations: 1. Operational passenger vehicles must be inspected once a year within the first 5 years, and every 6 months after exceeding 5 years; 2. Trucks and large or medium-sized non-operational passenger vehicles must be inspected once a year within the first 10 years, and every 6 months after exceeding 10 years; 3. Small and mini non-operational passenger vehicles are exempt from inspection for the first 6 years, but must apply for an inspection mark every two years. Currently, cross-regional annual inspections are also possible. The procedure for cross-regional entrusted inspection requires the vehicle owner to first apply to the original registration location before the annual inspection can be conducted, and an application must be submitted to the vehicle management office of the original registration location every year.
