Is it illegal to install a roof box on a sedan?
2 Answers
Installing a roof box on a sedan is not illegal. However, regulations stipulate that for passenger vehicles carrying cargo on roof racks, the height from the top of the vehicle must not exceed 0.5 meters, and the height from the ground must not exceed 4 meters. Exceeding either of these limits may result in a traffic ticket from the police. Relevant information about roof racks is as follows: 1. A roof rack is a device installed on the roof of a vehicle for carrying items, thereby increasing the interior space. Roof racks are convenient for carrying large amounts of luggage during travel. 2. Installing a roof rack increases the vehicle's wind resistance, leading to higher fuel consumption. Therefore, if not used for an extended period, the roof rack should be removed. Roof racks are suitable for medium to large vehicles such as commercial vehicles and SUVs.
Generally, installing a roof box on a sedan is not illegal, but it must comply with local traffic regulations. In daily life, I often see friends doing this to carry more luggage for trips, but the key point is that the total height must not exceed the limit. For example, in China, the height from the roof box to the top is limited to within 0.5 meters, and the total height including the vehicle body should not exceed 4.2 meters. After installation, ensure it does not block the front or rear view. Also, avoid making it too heavy, as it may affect the car's balance and cause shaking at high speeds. When installing, purchase a certified product and securely fasten the base bolts to prevent loosening and falling, which could injure someone. I’ve also seen cases where people didn’t measure the height properly and were stopped by traffic police, fined, and penalized with points—quite a loss. It’s advisable to check before traveling, especially for long trips, as safety comes first. During routine maintenance, inspect the fixtures to avoid issues caused by aging.
