Is Installing a Rear Spoiler Illegal?

[MacDamian]

If a car is fitted with a rear spoiler without undergoing the modification registration at the vehicle management office, it is considered illegal. The following vehicle modifications are not considered illegal: 1. Rear Spoiler Modification: When modifying a rear spoiler, the owner must file a record with the vehicle management office in advance. After the modification is completed, the vehicle must be photographed again to update the photo on the vehicle registration certificate. 2. Vehicle Body Color: The body color can be changed, but within 10 days, the vehicle must be photographed again at the vehicle management office to apply for a modification registration. Certain color schemes used by law enforcement vehicles are not allowed to be changed. 3. Partial Painting: If the change in body color covers less than 30% of the vehicle, there is no need to update the vehicle registration certificate through the vehicle management office. Additionally, wheels can be modified, but the size must remain the same as the original vehicle. The color or appearance can be changed freely, and no special registration for modification is required.
