Why doesn't China allow car modifications?

[CharlieLee]

Chinese law does not prohibit car modifications, but it does ban illegal modifications and unauthorized modifications, as such modification behaviors have certain impacts on vehicle safety and management, hence they are not allowed. Additional information is as follows: 1. Hazards of illegal modifications: Modified cars on the road pose certain safety hazards, and once a traffic accident occurs, the consequences could be unimaginable. For example, if the electrical circuit is altered and the modification is not done properly, it can easily leave a fire hazard; if the car's chassis structure is changed, it will affect the vehicle's tires, suspension, and braking system; if the quality of the selected parts is poor, it can easily increase the likelihood of accidents during driving. Many cases of vehicle spontaneous combustion and traffic accidents are caused by unauthorized modifications. 2. Illegal modifications include: Illegal modifications refer to modifications to the vehicle's appearance, power system, transmission system, and braking system that exceed the original design load capacity and functions permitted by national laws and manufacturer agreements. This includes the replacement of key components.

I think the strict regulations on car modifications in China are mainly due to safety concerns. As an ordinary person who drives to work every day, I certainly don't want to encounter illegally modified cars on the road—what if the engine or brakes were tampered with, leading to loss of control or spontaneous combustion? That would be extremely dangerous! I've seen news reports about people who modified their exhaust systems and chassis without authorization, resulting in excessive noise or frequent rollover accidents, endangering themselves and others. Modified cars may not meet the Ministry of Transport's standards and could fail annual inspections; if caught by the police, fines and penalty points would follow. Additionally, environmental protection is another key point. China is promoting new energy vehicles, and modifying old cars increases emissions, polluting the air. In short, these restrictions are in place to ensure safer travel for everyone. Personally, I fully support them—safety first, don't risk trouble for temporary thrills.

From a parent's perspective, I completely understand why China doesn't allow random car modifications. Safety is the top priority. With children in my family, I worry that modified vehicles might be unstable or have poor crash performance. For example, adding flashy rims or headlights could reduce braking effectiveness. China emphasizes standardized driving environments, and banning illegal modifications helps reduce street racing and public disturbances. Environmentally, modified cars with excessive emissions worsen air quality. These regulations help maintain public order and prevent young drivers from impulsive modifications leading to accidents. Moreover, I've heard that insurance companies don't cover modified cars, leaving owners fully liable for any issues. Protecting family safety is paramount, and following the rules is always the right approach.

China does not allow arbitrary car modifications, primarily due to traffic management and safety risks. Regulations require vehicles to comply with national standards. Unauthorized modifications, such as altering the engine or suspension system, may affect braking or steering functions, increasing the likelihood of accidents. Environmental factors are also significant, as modifications that enhance power can increase emissions and pollution. Additionally, to prevent illegal modifications and street racing that disrupt traffic order, the police strictly inspect vehicles with flashy exterior modifications. Overall, China promotes uniform standards to ensure road safety and efficiency.
