Is the vehicle inspection required annually or biennially?

[LaDelilah]

For passenger cars and blue-license-plate minivans, within the first six years after new vehicle registration, the inspection is required every two years; after six years, it becomes an annual inspection; after ten years, it's an annual inspection, and after fifteen years, it's a semi-annual inspection. The relevant explanations are as follows: Introduction: Vehicle annual inspection is also known as motor vehicle inspection. Depending on the usage nature of the motor vehicle, the inspection items and scope vary. According to the definition in the "Requirements for Motor Vehicle Inspection Institutions in the Evaluation of Qualification Recognition Capability of Inspection and Testing Institutions," motor vehicle inspection includes three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive performance inspection of vehicles. Regulations: If a vehicle is found by traffic police on the road without an annual inspection, the owner will be fined or the vehicle will be impounded. At the same time, in insurance contracts, vehicles that have not undergone timely annual inspections are considered unqualified, and no claims will be paid in the event of a car insurance accident.
