Which Vehicles Require Biannual Inspections?
3 Answers
Operational passenger vehicles over 5 years old require inspection every 6 months, totaling twice a year. Trucks and large/medium-sized non-operational passenger vehicles over 10 years old need inspection every 6 months, twice annually. Small and mini non-operational passenger vehicles exceeding 15 years require semiannual inspections, twice yearly. Below are motor vehicle annual inspection details: 1. Document verification: Check for vehicle manual, certificate of compliance (import vehicles' commodity inspection certificate), and completeness of factory inspection marks on the vehicle body. 2. Dimensional measurement: Measure internal/external contours including wheelbase and axle track. Specific measurements include length, width, height, cargo compartment panel height/area, wheelbase, and axle track. 3. Complete modification registration form: Conduct item-by-item inspection per technical standards. Upon passing, fill out the "Initial Motor Vehicle Inspection Modification Registration Form" and document curb weight, load capacity, passenger capacity, and cabin occupancy as per manufacturer specifications.
I heard from a friend about vehicle inspections recently. Now, vehicles over 15 years old no longer require two inspections per year; it's been changed to one annual inspection. The vehicles that still need biannual inspections are mainly commercial and large vehicles. For example, long-distance buses over 5 years old must undergo an on-site inspection every six months. Similarly, for freight companies, medium and heavy trucks over 10 years old must be inspected every six months, or they risk being stopped by traffic police. There are also special vehicles like hazardous chemical transport trucks, which must strictly adhere to biannual inspections regardless of their age. Due to their high usage intensity, frequent inspections help prevent safety hazards like brake aging and tire wear.
My uncle is in the transportation business, and his heavy-duty truck requires biannual inspections once it exceeds 10 years in age. Vehicles that need frequent inspections are mainly heavy-duty trucks, such as those over 4.5 tons, which must undergo semi-annual inspections after 10 years of use. School buses face even stricter regulations, requiring inspections every six months regardless of their age. There’s a tourist bus in our neighborhood, and the driver mentioned that passenger transport vehicles also join the biannual inspection list after five years. These regulations are primarily in place because such vehicles carry more passengers and accumulate high mileage, making critical systems like steering and braking prone to issues. Regular inspections help prevent unsafe vehicles from operating on the road.
