The inspection validity period refers to the vehicle inspection time. Vehicles can apply for inspection within 3 months before the annual inspection date. Non-commercial vehicles are exempt from on-site inspection for the first 6 years, requiring only a biennial inspection label application. For vehicles older than 6 years but less than 10 years, inspections are required every 2 years, meaning private cars only need on-site inspections twice within 10 years—specifically in the 6th and 8th years. Private cars aged 10-15 years require annual inspections, while those over 15 years old require inspections every 6 months. Commercial passenger vehicles must undergo annual inspections if under 5 years old, and every 6 months if older than 5 years. Trucks and large/medium non-commercial passenger vehicles require annual inspections if under 10 years old, and every 6 months if older than 10 years. Motorcycles require biennial inspections if under 4 years old, and annual inspections if older than 4 years. Key items covered in vehicle annual inspections include: Exterior inspection: Checks include vehicle lights, body appearance, suspension, sunroof, and tires—ensuring lights function properly, no modifications to body color or suspension, etc. Emission test: Verifies whether tailpipe emissions meet national standards during high-speed operation. On-site inspection: Focuses on the braking system, headlights, horn, and chassis. Violation check: All outstanding traffic violations must be cleared before the inspection to pass. Vehicle inspections can be conducted up to 90 days in advance but must not be overdue. Consequences of overdue inspections include: Overdue vehicles are prohibited from road use. Driving an overdue vehicle incurs a 3-point penalty and a 200 CNY fine. In case of an accident, the driver bears full or primary liability, and insurance claims are void. Driving an overdue vehicle constitutes illegal operation and may result in vehicle impoundment.
