What are the inspection period regulations for diesel vehicles?
2 Answers
For diesel vehicles within the first 6 years of registration, they are exempt from physical inspection twice (inspection marks must be applied for every two years without requiring on-site vehicle testing). At the 6th and 8th year, the vehicle must undergo on-site inspection. For private vehicles over 10 years old, the original inspection cycle still applies: annual inspection for vehicles aged 10-15 years, and semi-annual inspection for vehicles over 15 years old. Below are relevant details: 1. New inspection rules: The updated regulations now include 7-9 seat non-commercial mini/micro buses (excluding minivans) within the 6-year exemption period. For non-commercial mini/micro buses (excluding minivans) aged 6-10 years, the inspection frequency changes from annual to biennial. 2. Regulations: Article 16 of the Implementation Regulations of the Road Traffic Safety Law stipulates: commercial passenger vehicles must be inspected annually within 5 years of registration, then semi-annually thereafter; trucks and large/medium non-commercial passenger vehicles must be inspected annually within 10 years of registration, then semi-annually thereafter.
The inspection regulations for diesel vehicles are quite specific. Having driven a diesel pickup for several years, I can share my personal experience. According to current policies, newly registered diesel vehicles are exempt from on-site inspections for the first six years, but you must apply for the inspection sticker online every two years. Between six to ten years, they require on-site inspections every two years; after ten years, annual inspections become mandatory. Diesel vehicles receive special attention due to stricter emission controls—tests include smoke opacity and pollutant levels, making them more prone to failing. I recommend owners check the exhaust system in advance and clean the DPF (Diesel Particulate Filter) to avoid inspection failures. Regular maintenance is key; otherwise, fines and repair costs will follow. With environmental protection being a growing priority, complying with regulations saves money and ensures peace of mind.
