Legal modifications for vehicles are as follows: Roof racks and side running boards can be installed: The height of roof racks installed on SUVs and MPVs must be within 300 millimeters, and the width of side running boards must not exceed 5 centimeters beyond the side profile of the vehicle. Vehicle body color can be changed: You can change the vehicle color through painting or wrapping, but you must register the change with the vehicle management office within ten days. Note that colors similar to those used on emergency vehicles such as police cars and fire trucks are not allowed. The grille and front/rear bumpers can also be modified: The style of the grille and front/rear bumpers can be changed. However, the installation of new grilles and bumpers must not alter the original length and width of the vehicle. The vehicle emblem is not allowed to be changed, and the bumpers must not have any obvious protrusions, such as the so-called "tow hooks" commonly referred to as "rogue hooks," which are prohibited.

As an average car owner, there are quite a few legal modifications you can make to your vehicle in 2021. For example, you can change the body color, but you'll need to register the change at the DMV. Wheel rims can also be swapped for different styles, as long as the size doesn't exceed the original factory specifications. Interior modifications are pretty much fair game—things like reupholstering seats, adding a sound system, or installing a mini bar are all safe. Adding small body kits is fine too, as long as the dimensions aren't altered in a way that affects safety. On the flip side, don't touch the engine, avoid modifying the exhaust system to make it too loud (which is illegal), and don't use excessively bright lights that could blind others, as these can lead to accidents or fines. When registering a new color, bring your ID and vehicle registration to the DMV and spend some time completing the process to stay compliant. Before changing rims, check the original factory specs to avoid exceeding them. In short, legal modifications can make your car more unique and enhance your driving experience, but remember not to cross the line where safety is compromised—otherwise, repair costs plus fines could end up costing you more than it's worth.
