How often should a car within ten years undergo annual inspection?

[Toby]

Cars over ten years old need to be inspected annually, while those over 15 years old require inspection every six months. Below are the relevant details: 1. Documents: The documents required for vehicle annual inspection include the vehicle's driving license, valid compulsory insurance policy, the owner's ID card, and all traffic violation records must be cleared in advance. For newly purchased vehicles, they are exempt from on-site inspection for the first six years, but every two years, the owner must collect the free annual inspection sticker and environmental protection sticker from the vehicle management office. To collect these, bring the vehicle's driving license and the current valid compulsory insurance policy to the designated window at the vehicle management office, with no fees charged. 2. After six years: Annual on-site inspection is required. 3. After 15 years: On-site inspection is required every six months.
