The legality concerning the bumper differs from state to state. Recently, there are a total of 21 states that have made it mandatory for the drivers to have bumpers installed on the vehicle. Some countries have also made it compulsory for the car owners to get the bumper replaced and repaired if they are broken. While it is not mandatory for car owners to have bumper protection, it is important to invest in this accessory to protect your vehicle’s rear and front end from the scratches due to parking.
