Can Homemade Cars Apply for Road Use?

[DerekDella]

Homemade cars cannot be driven on the road if they do not meet the relevant legal requirements. Registration: This refers to the initial application by the owner or user of a motor vehicle to the public security authorities for the issuance of a license plate, vehicle registration certificate, etc. It is a prerequisite for the legal operation of a motor vehicle on the road. Without proper registration, the vehicle does not enjoy the corresponding rights stipulated by law, nor is it recognized or protected by law. Additionally, the owner may face adverse legal consequences. Temporary Road Use: Chinese law has clear regulations for such situations. If an unregistered motor vehicle needs to be temporarily driven on the road, it must obtain a temporary pass. The temporary pass for motor vehicles is issued by the public security authorities and serves as a special management measure for vehicles that have not yet obtained a license plate or registration certificate but need to be driven on the road. It is also an important part of the overall license and registration management system.

To be honest, I've pondered this issue for a long time. Want to legally drive a homemade car in China? Nearly impossible! A car with a self-welded steel frame and an engine salvaged from a junkyard wouldn't even make it past the DMV's doorstep. Just the announcement catalog and 3C certification alone can stop you dead in your tracks, not to mention needing a full set of compliance certificates and vehicle conformity documents. Some people always cite foreign vintage car meetups as examples, but here, even modifying an exhaust pipe might draw police attention. If you ask me, if you really want to express individuality, you're better off buying a compliant chassis and modifying the body, or keeping an eye on products from certified custom car manufacturers.

Having been in the car modification scene for over a decade, I've witnessed too many DIY car tragedies. Last year, a buddy spent three years welding a retro sports car, only to have it rejected at the inspection station—they wouldn't even let it on the testing line. The core issue is vehicle identity certification: the chassis number needs to be registered with the DMV, the engine must have a factory nameplate, and the windshield must bear the national safety certification mark. Even if you build everything to national standards, who's going to issue you a vehicle compliance certificate? If caught on the road, it's considered an illegally assembled vehicle—confiscation and mandatory scrapping with no room for negotiation. If you're serious about fulfilling your car-building dream, I suggest obtaining specialized vehicle manufacturing qualifications, though the cost would easily run into tens of millions.

From a technical perspective, the biggest issue with homemade vehicles is safety loss of control. Our lab tested a civilian-built car where the steering column pierced directly into the cabin during a 60km/h collision, and the homemade brake lines burst under high temperatures. Even if you use top-tier components, welding techniques, body stress calculations, and electronic system integration all require professional equipment for validation. One shortcut was to partner with a certified company to use their qualification certificates, but since last year, these partnership channels have been largely closed off.
