The Connecticut state law states:
"
No person shall operate or cause to be operated any bus, truck, truck-tractor, full trailer or semi-trailer of registered gross vehicle weight exceeding 3 tons on any public highway unless the same is equipped with suitable metal protectors or substantial flexible flaps behind the rearmost wheels; and, in case the rear wheels are not covered at the top and the rear by fender, body or other part of the vehicle, the rear wheels shall be covered at the top and the rear by protective means of such standard type or design and so installed as to reduce - as far as practicable - such wheels from throwing dirt, water or other materials on the windshields of following vehicles, except in cases in which the motor vehicle is so designed and constructed that the above requirements are accomplished by reason of the fender or body construction or other means of enclosure"
There is no federal law requiring them nationwide, as this matter is not addressed by the FMCSA.

In North Carolina, mud flaps are required for certain vehicles, specifically those that are over a certain weight limit, such as trucks and trailers. The state's laws aim to prevent debris from being thrown up by tires, which can pose hazards to other vehicles.

this depends on where the truck is registered and to what the laws are of that region.Added: (in the US) Commercial vehicles engaged in interstate commerce must be equipped with splash guards by DOT and ICC regulation and according to most state laws. This is one of the many things that 'weigh stations' check for on interstate and US highways, which can be seen at the entrance to most states and at intervals throughout the state.ADDED: Mudflaps are not regulated under the Federal Motor Carrier Safety Regulations, it is a State law in those states that require them.
In Washington State, vehicles are generally required to have mud flaps if they are designed to carry a load or are over a certain weight. Specifically, trucks and trailers with a gross vehicle weight rating (GVWR) of over 10,000 pounds typically need to have mud flaps installed. However, the law does not specify that you must have four mud flaps; instead, the requirement is based on the vehicle's configuration and use. Always check the latest local regulations to ensure compliance.
