The knowledge test trips up many first-time applicants. Here's exactly what to study and how to walk in prepared.
The Utah DLD written knowledge test is based on the Utah Driver Handbook (REV 3.2026). It is not timed but generally takes 30 to 45 minutes to finish. You must score at least 80% to pass.
Retake policy. You can take up to two written knowledge tests per day if the division can facilitate it. Your application fee covers three attempts within 12 months; after three failures you may pay another fee for three more attempts. A written-retest appointment is required if you need to return after a failed attempt.
Where to take it. The test is given at a Utah Driver License Division field office. All services should be scheduled by appointment at dld.utah.gov — walk-ins experience much longer wait times because appointments take priority.
Traffic Safety and Trends Exam. All first-time regular Class D applicants must also pass an additional online-only exam with 100%; about 50% of its questions cover significant causes of Utah traffic deaths. You can retake it as often as needed before licensing. It is only offered on the DLD website.
Driver education. Applicants under 19 generally complete an approved driver education course. Applicants 19 or older may be licensed without driver ed if they hold a learner permit for 90 days and complete at least 40 hours of driving practice (10 of those after sunset).
Utah is the first state in the country to have a 0.05 BAC limit for adult drivers 21+ (since December 2018). The CDL limit is 0.04. Under 21 is "Not-a-Drop" — any measurable amount of alcohol is illegal. Impairment starts with the first drink.
First DUI conviction (21+): license suspended 120 days; second or subsequent: 2 years. First DUI also triggers an Ignition Interlock Device (IID) for 18 months (or 3 years if under 21 at arrest). Felony DUI = 3-year IID; automobile homicide = 10-year IID.
Under 21 with any measurable alcohol: driving privileges denied 6 months first offense, 2 years or until age 21 for a second within 10 years. Refusing a chemical test revokes your license 18 months first refusal, 36 months subsequent (2 years if under 21).
Pass the written and vision tests to get a learner permit. Minimum age to take the driving skills test at the DLD is 16 (15 with a third-party tester or high school). Under-21 drivers hold a Provisional Class D license with a stricter 70-point hearing threshold (vs. 200 points for 21+).
Maintain at least a two-second following distance behind the vehicle ahead, and increase it in bad weather or poor visibility. On the freeway, never drive in the emergency lane — it is for emergency use only.
20 mph in school zones during recess or opening/closing hours; 25 mph in any business or residential area; 55 mph on major highways; 65/70/75/80 mph on rural interstate as posted. The basic speed law says you may never drive faster than is reasonably safe.
Signal at least 2 seconds before any turn or lane change, and any time you pull to or from a curb. You may turn right on red after a complete stop unless otherwise posted. Left-on-red is allowed only from a one-way street onto another one-way street.
Stop for a bus with alternating flashing red lights. Two-lane road: both directions stop. Four-lane without median: both directions stop. Divided highway with a median or a 5+ lane road with a center turn lane: only traffic behind the bus must stop. Illegal-passing fines can run up to $3,000.
15 ft from a fire hydrant; 20 ft from a crosswalk or a fire-station driveway; 30 ft from a flashing beacon, stop, yield, or traffic signal; 50 ft from the nearest rail of a railroad crossing. Park within 12 inches of a curb. Never park on a sidewalk, bridge, or interstate shoulder.
Buckle up — it's the law. Children 8 and under must be in an approved child safety seat or booster unless they are 57 inches tall. Rear-facing until age 2 & 30 lb; forward-facing with a harness until age 4 & 40 lb. The ticket fine may be waived by completing a 30-minute online safety-belt course.
Utah requires 80% to pass the written knowledge test. Aim for 90%+ in practice so nerves or an unusual question can't drop you below the cutoff. The test is not timed — don't rush.
Memorize BAC limits, parking distances, signaling times, following distance, and suspension periods. These specific numbers appear on virtually every Utah test.
The Weak Spots mode saves every question you got wrong. Replay it until you're hitting 90%+ before going to the DLD office.

Utah's defaults catch people out: 20 mph in school zones, 25 mph in business or residential areas, 55 mph on major highways, 65–80 mph on rural interstate (as posted). Reduce speed for weather, curves, hills, and work zones.
Sign questions are visual — shape, color, and meaning all matter. Use the Road Signs Quiz mode to practice all signs before test day.
