Utah Driving Laws 2026: Speed Limits, DUI BAC and Utah Driver License Division Road Rules for the Permit Test

What are the speed limits in Utah when no sign is posted? Utah law sets 20 mph in a reduced-speed school zone, 25 mph in an urban district, and 55 mph in other locations; rural interstate limits may be posted at 65, 70, 75, or 80 mph. Utah became the first state in the U.S. to lower the DUI threshold to 0.05% BAC in December 2018. Under the Not-a-Drop Act, a driver under 21 with any measurable amount of alcohol faces a six-month denial for a first offense. Texting while driving is a Class C misdemeanor with a maximum $100 fine and 50 points. The Utah written knowledge test is based on the Driver Handbook and requires 80% or better to pass.

1. Utah Speed Limits: 65–80 MPH Rural Interstates, Urban Districts & School Zones

What is the speed limit in a residential area in Utah, and what happens if no sign is posted? Speed limits are set by state law; when no sign is visible, these default limits apply:

Key test point: Utah's basic speed law requires a reasonable and prudent speed for existing conditions. The statutory defaults are 20 mph in a reduced-speed school zone, 25 mph in an urban district, and 55 mph in other locations; rural interstate limits may be posted at 65, 70, 75, or 80 mph.

2. Utah Right-of-Way: Pedestrians & 4-Way Stop Rules

Who has the right-of-way at a 4-way stop in Utah, and when must drivers yield? At a four-way stop, the driver who arrives first proceeds first. If two drivers arrive at the same time, the driver on the left yields to the driver on the right. Drivers must also yield to pedestrians and bicyclists still in an intersection.

3. Utah Turn Signal Law: Signal for at Least 2 Seconds Before Turning or Changing Lanes

Can you turn right on red in Utah, and how long must you signal before a turn or lane change? Utah requires a turn or lane-change signal continuously for at least the last 2 seconds before the movement. Effective May 6, 2026, Utah law does not require a turn signal when entering or exiting a roundabout.

Right turn on red

Permitted after a full stop unless a sign prohibits it. Yield to pedestrians and cross traffic.

No right turn on red

When posted, you must wait for a green light before turning right.

Left turn on red

Only allowed from a one-way street onto another one-way street, after a full stop.

Left turn from two-way street

Start from the left lane; end in the left lane of the cross street.

Right turn

Stay as close to the right curb as possible; end in the right lane.

U-turns

A U-turn is allowed only when it can be made safely without interfering with traffic. Do not make one on a curve or near a hill crest unless the vehicle is visible for at least 500 feet in both directions, on railroad tracks or a railroad grade crossing, on a freeway, or where a traffic-control device prohibits it.

4. Utah Lane Markings: Keep Right Except to Pass, Solid vs Broken Lines & Interstate Rules

When can you use the center turn lane in Utah, and what do solid versus broken yellow lines mean for passing? Lane rules determine where you drive and when you can cross a line, all commonly tested on the knowledge exam.

Center turn lane (CTSL)

Used only to prepare for or make a left turn from or into the roadway, or a permitted U-turn; not for through travel. Generally, do not enter more than 500 feet before the turn, and after turning into the lane do not travel more than 500 feet unless the statutory queue/next-turn exception applies.

Solid white line

Do not cross; marks the edge of the road or a lane that should not be changed.

Solid yellow line (your side)

No passing allowed.

Broken yellow line

Passing allowed when safe.

Solid + Broken yellow centerline

Passing allowed only on the broken-line side.

Utah zipper merge rule: At a congested merge point, use both lanes until the merge point, then alternate into the single lane while yielding as required. A violation is an infraction.

5. Passing in Utah: 200-Foot Oncoming Clearance, 100-Foot No-Passing Areas & 3-Foot Bicycle Rule

When is it illegal to pass another vehicle in Utah, and how close to an intersection can you pass? Passing is one of the most dangerous maneuvers on the road, Utah law sets strict distance and visibility rules:

• Only pass on the left, using the oncoming lane, when it is safe and legal.
• Do not pass when your view is obstructed on a hill or curve; within 100 feet of or while traversing an intersection or railroad grade crossing unless a traffic-control device indicates otherwise; or when your view is obstructed within 100 feet of a bridge, viaduct, or tunnel.
• The vehicle being passed must not speed up while you are overtaking.
• Return to your lane before coming within 200 feet of oncoming traffic.
• When passing a bicyclist or vulnerable highway user, leave at least 3 feet of clearance.
• Never pass a stopped school bus with flashing red lights, this applies in both directions on undivided roads.
• You may pass on the right when the vehicle ahead is making or preparing to make a left turn, or on a roadway with unobstructed pavement wide enough for two or more lawful lines of traffic in your direction. The movement must be safe, and you may not drive off the roadway to pass.

6. Utah Following Distance: 2-Second Rule Plus 2 Extra Seconds at Night

What is the safe following distance in Utah, and how does weather change it? The Utah Driver Handbook uses at least a 2-second following distance under normal freeway conditions; increase the time under adverse conditions.

7. Utah School Bus Law: Stop Distance, Move Over & School Zone Flashing Light Rules

Do you have to stop for a school bus on a divided highway in Utah, and what is the penalty for passing one illegally? Utah has different stop rules for two-lane roads, four-lane roads, divided highways, and highways with five or more lanes.

School Buses

• When a school bus stops with flashing red lights and an extended stop arm, all traffic in both directions must stop on undivided roads.
• On roads with a true median or physical barrier, only traffic behind the bus must stop, oncoming traffic may proceed.
• On a four-lane roadway without a median, traffic in both directions must stop. On a highway with five or more lanes, which may include a left-turn or two-way left-turn lane, opposite-direction traffic is not legally required to stop.
• You must remain stopped until the red lights stop flashing and the stop arm is retracted.
• Penalties escalate: a first offense carries at least $1,000 and 10 hours of compensatory service; a second within five years at least $2,000 and 20 hours; a third or subsequent offense within five years at least $3,000 and 40 hours.
• Railroad crossings: School bus drivers are required to stop at all railroad crossings, check both directions and listen, proceed only when safe, and never shift gears on the crossing.

Emergency Vehicles

• When you see or hear an emergency vehicle (police, fire, ambulance) with lights or siren: pull to the right edge of the road and stop. Do not block intersections.
• Move Over Law (Utah): When approaching a stationary vehicle adjacent to a highway, outside an apparent legal parking area, with flashing hazard lights, reduce speed, provide as much space as practical, and, when practical and safe, move into a lane not adjacent to the vehicle. A conviction requires a four-hour live defensive-driving course within 90 days; failure to complete it results in a 90-day license suspension.

8. Utah DUI: First State at 0.05%, Not-a-Drop Under-21, 18-Month Refusal Revocation

What is the legal BAC limit in Utah for drivers under 21, and can you refuse a breathalyzer? Utah DUI laws use different thresholds and license consequences for adult, under-21, and commercial drivers.

9. Utah Seat Belt Law: Under-8 in Car/Booster, Rear-Facing Until Age 2 AND 30 Lbs

Who gets the ticket if a passenger is not wearing a seat belt in Utah? If anyone under 16 is unrestrained, an officer may stop the vehicle and issue a citation. Occupants age 16 and older may be cited for a belt violation when the vehicle is stopped for another reason.

10. Utah Parking Rules: 15-Foot Hydrant, 50-Foot Railroad & Urban District Rules

How far from a fire hydrant must you park in Utah, and is it legal to park on a bridge? Utah parking rules set specific distances from hydrants, crosswalks, traffic-control devices, and railroad crossings. Know where you cannot park:

• Within 15 feet of a fire hydrant
• On a crosswalk or within 20 feet of a crosswalk
• Within 30 feet of a flashing beacon, stop sign, yield sign, or traffic-control signal
• Within 50 feet of the nearest rail at a railroad crossing
• On a sidewalk, in front of a driveway, or on a bridge
• At a red-painted curb or in a red zone, or anywhere official signs prohibit stopping
• Double parking (alongside a vehicle already parked at the curb)
• When parking next to a curb, the back wheel must be no more than 12 inches from the curb.
• Headed downhill: turn wheels toward the curb. Headed uphill with a curb: turn wheels away from curb. Uphill without a curb: turn wheels toward the shoulder.

11. Driving in Utah Weather: Wasatch Front Inversion Fog, I-15 Ice & Desert Flash Floods

Are headlights required when visibility is poor in Utah, and what should you do if your car starts to hydroplane? Utah driving conditions can include mountain snow and ice, desert heat, flooding, fog, and rapidly changing visibility; adjust speed and following distance to the conditions.

• Headlights required in Utah from sunset to sunrise and any time visibility is less than 1,000 feet. At night add at least 2 seconds to your following distance.
• In heavy fog, use low beams, high beams reflect off fog and reduce visibility.
• If you start to hydroplane, ease off the gas gently. Do not brake hard or turn sharply.
• In icy conditions, brake gently well in advance. Start slowing earlier than normal. Leave extra following distance.
• If your car goes into a skid, steer in the direction you want the front of the car to go. Do not overcorrect.
• Never use cruise control on wet, icy, or slippery roads.

12. Utah Points: 200 Adults / 70 Under-21 in 3 Years, Texting = 50, Wrong Way = 60

How many points does a speeding ticket add to your Utah license, and what happens at the point threshold? Utah assigns points for moving violations. Reaching 200 points in three years if over 21, or 70 points in three years if under 21, triggers a Driver Improvement hearing; the outcome may include probation, a defensive-driving course, denial, or suspension.

Note: Half of the total points on your record are removed after one full year without a moving traffic conviction; two successive years clears all points. Points for an individual conviction are removed three years after the violation. A Division-recommended defensive-driving course can remove 50 points once in a three-year period.

13. Utah Headlight Law: 1,000-Foot Visibility Trigger, Dim 500 Oncoming & 300 Following

When must you dim your high beams in Utah, and how far away does an oncoming car need to be? Utah requires headlights from sunset to sunrise and when persons or vehicles cannot be clearly seen 1,000 feet ahead; high beams must be dimmed at specific distances.

Key test point: Oncoming traffic = dim at 500 feet. Following another vehicle = dim at 300 feet.

14. Night Driving in Utah: Add 2 Seconds at Night, Desert Dark Skies & Wildlife

What does "overdriving your headlights" mean in Utah, and why is it dangerous? Utah's handbook requires headlights at night, dimming at the required distances, a longer following gap, and a reasonable and prudent speed for limited visibility.

15. Utah Texting Law: Class C Misdemeanor, $100 Fine, 50 Points, Primary Offense

Is it legal to use your phone while driving in Utah, and can an officer pull you over for texting? Utah prohibits specified manual use of a handheld wireless communication device while a motor vehicle is moving on a highway, with separate restrictions for drivers under 18.

Key test point: Officers may stop a driver when they observe prohibited texting or other specified manual device use. A texting conviction also carries 50 points under Utah's point system.

16. Utah Railroad Crossings: 15–50 Feet Stop Rule & Gate/Signal Requirements

How far from the tracks must you stop at a railroad crossing in Utah, and what vehicles must always stop even when no train is coming? When a stop is required, Utah's handbook places the stop between 15 and 50 feet from the nearest rail.

Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.

17. Utah Roundabouts: Yield on Entry, Lane Selection & How to Exit Correctly

Utah roundabouts operate counterclockwise. Slow as you approach, yield to circulating traffic and pedestrians, and enter when a safe gap is available. Effective May 6, 2026, Utah law does not require a turn signal when entering or exiting a roundabout.

Key test point: Entering drivers yield to traffic already inside. Effective May 6, 2026, a turn signal is not required when entering or exiting a roundabout.
