Utah Driving Laws — Complete Guide (2026)
Understanding Utah's driving laws is critical for passing the permit test and staying safe on the road. This guide covers all the major laws you need to know.
DUI & Alcohol Laws
Utah has the strictest DUI laws in the country. The legal BAC limit for drivers 21 and over is 0.05% — lower than the national standard of 0.08%. For drivers under 21, Utah enforces a zero-tolerance policy, meaning any detectable alcohol is illegal.
- •0.05% BAC limit for drivers 21+
- •Zero tolerance for drivers under 21
- •Implied consent — refusing a BAC test means automatic license suspension
- •Penalties include fines, jail time, and license revocation
Speed Limits
Utah's basic speed rule requires you to drive at a speed that is reasonable and safe for conditions — regardless of the posted limit.
- •Residential areas: 25 mph (typical)
- •School zones: 20 mph when children are present
- •Urban highways: 55–65 mph
- •Rural freeways: up to 80 mph
- •Too fast for conditions is illegal even under the limit
Seat Belt & Child Safety
All vehicle occupants in Utah are required to wear seat belts. The driver is responsible for ensuring all passengers under 16 are properly restrained.
- •All occupants must wear seat belts
- •Children under 8 (or under 57 inches) need a child safety seat
- •Driver is responsible for passengers under 16
Cell Phone & Texting Laws
Utah prohibits texting and using handheld electronic devices while driving. This is a primary offense — meaning an officer can pull you over specifically for phone use.
- •Texting while driving is illegal
- •Handheld phone use prohibited while driving
- •Set GPS and adjust settings before you start driving
- •Pull over if you need to use your phone
Right-of-Way Rules
Understanding right-of-way rules prevents accidents and is heavily tested on the Utah permit exam.
- •At a 4-way stop: first to stop goes first
- •Simultaneous arrival: left yields to right
- •Pedestrians always have right of way in crosswalks
- •Yield when entering from driveways, alleys, or parking lots
