Medium-speed vehicle (MSV) is a vehicle registration category in some states of the United States where applicable vehicles are allowed to travel on roads at speeds up to 35–45 mph (56–72 km/h). The safety regulations for MSVs are more stringent than those for Low-speed vehicles.[1]
Montana's SB0185 was the first law to define this class of vehicle.[2] Minnesota[3] and Washington State[4] have laws that allow for vehicles that travel up to 35 mph (56 km/h), Tennessee's laws allow for vehicles that travel up to 40 mph (64 km/h), and Colorado, Kentucky, Montana, Oklahoma, Oregon, and Texas all have laws allowing MSVs that travel up to 45 mph (72 km/h). Maryland's law considers the speed capability of the particular vehicle.[1]
