Can a Sedan with Scissor Doors Pass the Annual Inspection?
2 Answers
It can pass the annual inspection if all procedures are completed. However, if the modification is not properly documented and the change registration is not applied for within 10 days after the modification, it will fail the inspection. Prohibited modifications include: 1. Wide Body Kits: Supercar-style wide body kits are only suitable for super highways. Most non-original wide body kits are hard to find replacement parts for, and in case of a collision, they can pose significant risks to life safety. 2. Hood Modifications: Original hoods are designed to bend and deform in stages during a collision, whereas modified hoods may pierce through the windshield, causing accidents. 3. Mushroom Head Exhaust Pipes: Mushroom head exhaust pipes reduce intake inertia, leading to decreased low-speed torque, increased fuel consumption, and poor low-speed performance. 4. Large Exhaust Systems: These reduce exhaust backpressure, resulting in decreased low-speed torque. Additionally, the engine exhaust valves are prone to burning out due to excessively high temperatures.
I've been repairing cars for over a decade and have seen many owners install scissor doors, thinking it's just about changing the door opening method. However, this modification actually has a significant impact on annual inspections. During inspections, officials check if the vehicle structure meets original factory standards. Scissor door modifications alter the hinge and door lock systems, which may not have passed safety certifications and can easily be deemed illegal modifications. If you make such changes without filing them with the vehicle management office, there's a high chance you'll fail the annual inspection, as this alters the requirements for body strength and reduces collision protection. I advise owners not to pursue temporary flashiness without first understanding the regulations, or else they'll have to spend money reverting the modifications or face penalties. Similar modifications like exhaust upgrades or suspension changes carry equally high risks.
