How to Legally Modify a Car?
2 Answers
Here is a detailed introduction to legal car modifications: 1. Scope of legal car modifications: Legal interior modifications refer to altering interior facilities, including replacing the steering wheel, installing sport seats, adding instrument equipment, and sound-deadening materials, etc. 2. Modification registration: Before modifying a car, consult the traffic management department to confirm whether the intended modifications are legal. You can apply for relevant registration, and once approved, the modifications are considered legal. Note: Illegal vehicle modifications refer to alterations to the appearance, power system, transmission system, or braking system that are not permitted by national laws or exceed the original manufacturer's design load capacity and functionality.
Having driven for fifteen years, I deeply understand the importance of legal modifications. In China, it's essential to comply with the Road Traffic Safety Law. For instance, if you change more than 30% of the vehicle's body color, you must register the modification with the vehicle management office. Engine modifications should not be extensive, and the original emission standards must be maintained; otherwise, the vehicle won't pass the annual inspection. Noise levels must also be controlled and should not exceed 85 decibels to avoid disturbing pedestrians. For safety, after modifications, the braking system and lighting must pass required tests. I recommend consulting certified modification shops that are familiar with local regulations—they can help you add spoilers or change rims without crossing legal boundaries. Remember, illegal modifications may result in fines or failed inspections, wasting money and time, so it's better to play it safe.
