Utah Driving Laws

Driver License Requirements: 
The minimum driving age in Utah is 16 years old. All drivers must have a valid license. Visitors from other states or countries may drive in Utah as long as they have a current driver license and are at least 16 years old.

Speed Limits: 
On most highways, the speed limit is 55 or 65 miles per hour, particularly in urban areas. Speed limits increase to 65 or 75 miles per hour on Interstate Highways and 65 miles per hour on some State Highways. These increased speeds are only allowed where they are clearly posted. Transition zones from one speed limit to another are indicated with pavement markings and additional signs.

Turning Right on a Red Light: 
Right turns are allowed on a red light after the vehicle has come to a complete stop, except where signs prohibit.

Seat Belt Laws: 
Children ages 8 and younger, unless over 57 inches tall, must be properly restrained in an approved child safety seat. Youths ages 8 through 18 must be restrained in a car seat or seat belt. For a person age 19 or older, not wearing a safety belt is a secondary offense. This law applies to all seating positions that are equipped with seat belts.

Helmet Use:
Helmet use is mandatory for motorcyclists and passengers under the age of 18.

Car and RV Rentals
If you don't drive to Utah, you may want to rent a car or recreational vehicle to get you to Utah's scenic, historic, and recreation areas. All major car rental agencies operate offices at the Salt Lake International Airport, and many have rental desks at major hotels. You can also find rental agencies in many of Utah's larger cities, but Salt Lake City has the greatest selection available. If you plan any off-highway or backroad adventures, a four-wheel drive vehicle is recommended. RVs and campers are also a great way to see the state.
