South Carolina Truck Mud Flap Law
South Carolina has no specific mud-flap statute. There is no state splash-guard width or clearance number to violate (per the NTEA state guide); a 2020 bill to add an 8-inch rule died in committee. Keep the rear wheels covered anyway. The moment you cross into Georgia or Florida, their tighter rules judge you. Skip any chart citing '49 CFR 393.86' for flap size; that is the rear impact guard, a different device.
A detail here is flagged medium confidence — confirm with the state statute before you rely on it.
