Street legal all terrain vehicles — Utah Permit Test

A Utah street-legal all-terrain vehicle on a highway may not exceed the lesser of the posted speed limit or 50 miles per hour.

Fifty is the machine’s ceiling whatever the sign says, because it was not built for highway speeds.

The street-legal ATV/UTV or FSV operating on a highway may not exceed the lesser of the posted speed limit or 50 miles per hour.

Where a Utah street-legal ATV is operated on a highway posted higher than 50 miles per hour, the operator must keep to the extreme right-hand side of the roadway and fit a reflector or reflective tape.

On a fast road the machine is the slow thing. Keeping right and being visible is all that makes it workable.

the operator shall operate the street-legal ATV/UTV or an FSV on the extreme right-hand side of the roadway and shall equip the street-legal ATV/UTV with a reflector or reflective tape

Anyone younger than 21 years of age operating a Utah street-legal all-terrain vehicle must wear a DOT-approved helmet.

It is the same age line as a motorcycle, because in a crash there is no more protection here than there.

Anyone younger than 21 years of age is required to wear a DOT-approved helmet.

A Utah street-legal ATV may be operated on a street or highway that has one lane in each direction.

One lane each way is a slow road by design. Wider highways are where the speed difference becomes dangerous.

All-terrain type I, a UTV or an FSV that meets the requirements may be operated as a street-legal ATV/UTV or a FSV on a street or highway that is a highway with one lane in each direction.

A Utah driver holding a Class D or commercial license is licensed to drive a street-legal ATV, utility-type vehicle, or full-size all-terrain vehicle.

No extra endorsement is needed. The ordinary car license already covers it once the machine is registered.

If you have a Class D or CDL, you are licensed to drive a street-legal ATV/UTV or FSV.

A Utah street-legal ATV must carry headlamps, tail lamps, a rear plate light, red rear reflectors, stop lamps, turn signals front and rear, a braking system other than a parking brake, a horn, a muffler, mirrors, and a speedometer lit for night use.

The list is everything a car has, because on a public road it has to be as visible and as controllable as one.
