A person shall not operate a truck, trailer, semitrailer or bus on a highway unless the vehicle is equipped with rear fender splash guards that comply with the specifications provided in this section. B. The splash guards: 1. Shall be attached in a manner that prevents the splashing of mud or water on the windshield of other motor vehicles. 2. Shall extend to a length of not more than eight inches from the ground. 3. Shall be wide enough to cover the full tread or treads of the tires being protected. 4.

Mud flaps have to be on medium and heavy duty trucks in Pennsylvania. This is the law and you can be fined if they aren't.

Yes, there are exceptions to gravel and log trucks, per the MS Highway Patrol. This of course makes no sense at all. They have also included Asphalt trucks. I am looking for the wording in MS that verifies same.
are truck tractors required mud flaps
In Oregon they are Michigan requires Mudflaps (anti-splash devices) on commercial vehicles.
All CMVs must have seven lights across the back.
That law tends to vary by state. In North Carolina, you're not actually required to have mud flaps. Other states may require it. I've never seen anything in the FMCSR pertaining to mud flaps, and it's unlikely that the feds mandate it, considering that states have leeway in determining whether or not they want to make them mandatory.
