If your vehicle has _________, check that they are securely mounted and in good condition whether or not they are required by law.

Currently, there are no federal regulations on splash guards (mud flaps). Each state is free to create its own regulations. Some states don't have any such regulations. Some other states regulate how mud flaps can be used without actually requiring that they be used. Check with your state's DMV or transportation department for the regulations for your state. However, if splash guards are installed on your vehicle, check that they are securely mounted and in good condition.
