How many years later does a compact car require two inspections per year?

[PeterDella]

Compact cars require two inspections per year after 15 years. Documents needed for vehicle inspection: original driver's license, copy of compulsory traffic insurance, copy of agent's ID card, and the vehicle. Inspection content: check whether the engine, chassis, body and its accessories are clean, complete and effective, whether the paint surface is uniform and beautiful, whether the main assemblies have been replaced, and whether they are consistent with the initial inspection records; check whether the vehicle's braking performance, steering control, lights, exhaust and other safety performance meet the requirements of the technical conditions for safe operation of motor vehicles; check whether the vehicle has been modified, remodeled, or transformed, whether the driver's license, license plate, and all vehicle file registrations are consistent with the vehicle condition, whether there are any changes, and whether approval and change procedures have been completed; check whether the license plate, driver's license, and enlarged license plate characters printed on the vehicle are damaged, altered, or illegible, and whether they need to be replaced.
