Privately installing a roof rack is not considered illegal as long as it does not exceed the specified height. Exceeding the height limit will result in a 1-point deduction by traffic police. Below is more information about installing roof racks on vehicles: 1. Legal Basis: Article 54 of the "Road Traffic Safety Law Implementation Regulations." 2. Height Regulations: (1) For heavy and medium-duty trucks, semi-trailer cargo, the height from the ground must not exceed 4 meters; for vehicles carrying containers, it must not exceed 4.2 meters. (2) For other cargo-carrying motor vehicles, the height from the ground must not exceed 2.5 meters. (3) For motorcycles, the height from the ground must not exceed 1.5 meters, and the length must not exceed the body by 0.2 meters. The width of cargo on two-wheeled motorcycles must not exceed the handlebars by 0.15 meters on each side; for three-wheeled motorcycles, the width must not exceed the body. Passenger vehicles are not allowed to carry cargo except on external roof racks and built-in luggage compartments. For passenger vehicles, cargo on roof racks must not exceed 0.5 meters in height from the roof or 4 meters in height from the ground.

As someone who frequently deals with cars, I believe installing a roof rack depends on local regulations. In China, laws strictly stipulate that vehicle modifications must not exceed limits, such as the height or size of the roof rack, otherwise it’s considered illegal modification. I’ve seen many car owners fined for improper installations, which also affect annual inspections. Safety-wise, original designs account for wind resistance and stability, and haphazard installations can lead to accidents, like luggage falling and injuring others at high speeds, with full liability on the owner. Don’t cut corners or save money by going to roadside shops—check DMV regulations or consult professionals first to ensure every detail is compliant. Legal installation is fine, practical and safe.

Last time I installed a roof rack on my car, only to be stopped by traffic police right after leaving home and fined for exceeding height limits. Regulations vary across provinces and cities - Beijing prohibits unregistered modifications while some southern cities might be more lenient. I understand everyone wants to increase practicality by loading stuff conveniently, but breaking laws means fines and penalty points. My personal advice: check local traffic regulations - for example, maximum load shouldn't exceed 300kg, and materials must meet fireproof standards. If unregistered, just complete a simple procedure at the DMV with minimal fees - much better than getting fined. Remember, illegal modifications not only incur fines but may also void insurance coverage in accidents, which really isn't worth it.

I enjoy tinkering with car accessories, and roof racks look much cooler while allowing more storage for trips. But be careful, as they're illegal in many places unless they're factory-certified or meet specific dimensions. I recommend buying standard compliant products, opting for low-profile, flush-mounted styles to avoid issues. Check regulations before installation, like local enforcement shared in online car enthusiast groups—strictness varies. Don't exceed weight limits, and ensure secure mounting to prevent rattling noise that bothers others or draws inspections. Simply put, staying legal means safety and peace of mind—avoid illegal mods due to high risks.
