North Dakota Truck Idling Law
North Dakota has no statewide idling time limit. The only idling-related provision is a 550-pound weight allowance for a fully functional APU / idle-reduction unit, applied administratively by the ND Highway Patrol under the federal allowance (23 U.S.C. 127). Some online lists wrongly attribute a 5-minute rule to the state; that is generic template text, not North Dakota law.
