Utah-Specific Rules

Minor & Provisional Licensing

  • The entry-level learner permit can be issued starting at age 15 and stays valid for 18 months from issuance.
  • Applicants 15-18 need 27 hours of high school classroom driver education (or 18 hours commercial/private, or 30 hours approved online), plus 6 hours behind the wheel and 6 hours of observation.
  • On top of driver education, applicants 15-18 need 40 hours of supervised driving with a parent or guardian, including at least 10 hours after sunset.
  • Applicants 19+ who've never been licensed can skip driver education by holding the permit 90 days and logging 40 hours of driving (10 after sunset); completing driver ed instead waives the 90-day hold.
  • Learner permit hold periods before a first license: 6 months at 16-17, no hold at 18 with driver ed, 90 days at 19+ without driver ed.
  • A 16-year-old license holder (not permit) can't drive midnight-5 a.m. except for agricultural work, commuting, school activities, or emergencies, unless a licensed driver 21+ rides along -- 15, 17, and older drivers have no such curfew.
  • A 16-year-old license holder may only carry immediate family passengers until six months have passed since the license was issued; this restriction doesn't apply at 15, 17, or older.
  • Drivers under 21 get a provisional Class D license so the Driver License Division can apply a lower point threshold before requiring a driver improvement hearing.

Licensing Procedure & Examinations

  • The written knowledge test is untimed (usually 30-45 minutes) and requires 80% or better to pass; up to two attempts are allowed per day.
  • One fee covers three written-test attempts within 12 months; after three failures, a new fee buys three more.
  • All first-time applicants must also pass a separate, online-only Traffic Safety and Trends Exam with a perfect 100% score -- about half its questions cover the state's leading causes of traffic deaths.
  • The driving skills test requires being at least 16 at a DLD office, or at least 15 through a certified third-party tester or high school; it runs about 20 minutes.
  • Only one driving skills test is allowed per day; after three failures a new fee is required, and all skills testing must finish within six months of paying it.
  • Written test scores stay valid 18 months for an entry-level learner permit but only 12 months for a 6-month renewal permit -- letting either expire means retaking the written test.
  • Passing the vision test requires 20/40 vision with at least 90 degrees of peripheral vision in one eye; drivers 65+ must pass a vision test at every renewal.
  • A regular Class D license (21+) expires on the holder's birthday 8 years after issuance; a provisional license (under 21) expires after only 5 years.
  • Current fees: $19 learner permit, $39 provisional Class D (under 21), $52 regular Class D (21+), $27 discounted renewal for drivers 65+.

DUI Laws & Penalties

  • Utah's BAC limit is 0.05% for drivers 21+ (0.04% for CDL holders) -- the lowest standard-license threshold of any state, versus 0.08% almost everywhere else.
  • Under the Not-a-Drop Act, a driver under 21 with any measurable alcohol loses all driving privileges for 6 months on a first offense, 2 years (or until 21, whichever is longer) on a second within 10 years.
  • A first DUI conviction means a 120-day license suspension for a driver 21+; a second or later conviction means a 2-year suspension.
  • Refusing a chemical test under implied consent means an 18-month license revocation on a first refusal (24 months if under 21), 36 months for a second or later refusal.
  • A first DUI conviction requires an ignition interlock device for 18 months (36 months if under 21 at arrest); a second or later DUI or alcohol-related reckless driving conviction extends it to 2 years.

Speed, Right-of-Way & Legal Rules

  • Utah's basic speed law: 20 mph in school zones during recess/arrival/dismissal, 25 mph business/residential, 55 mph major highways, up to 80 mph on some rural interstates -- among the highest posted limits in the country.
  • Courts must fine highway work-zone speeding at least double the regular speeding fine.
  • Flex lanes are rush-hour lanes controlled by overhead signals, not fixed markings: a green arrow allows use, a red X prohibits it.
  • I-15 express lanes are free for vehicles with two or more people, motorcycles, or a clean-fuel C decal ($10 one-time fee); a single-occupant vehicle without a decal needs a UDOT express pass.
  • At a single-point urban interchange, a U-turn from the off-ramp back onto the freeway is legal only while facing a green arrow when the maneuver begins.

Sharing the Road

  • Drivers must leave at least 3 feet of clearance when passing a bicyclist or other vulnerable highway user.
  • Motorcycle lane filtering is legal only on a roadway/off-ramp with two or more same-direction lanes, a posted limit of 45 mph or less, the motorcycle under 15 mph, the other vehicle stopped, and only if it can be done safely -- never on an on-ramp.
  • Under the Move Over Law, a conviction for not moving over/slowing for a stopped emergency or roadside vehicle requires a 4-hour live defensive driving course within 90 days, or a 90-day license suspension.

Crashes, Insurance & Suspensions

  • A crash must be reported to 911 immediately if it involves injury, death, or at least $2,500 in property damage -- even a single-vehicle crash with no other driver involved.
  • Failing to stop after a crash involving injury is a third-degree felony; failing to remain at any crash scene can mean up to a year's license suspension, up to a year in jail, and a fine up to $2,500.
  • Driving without insurance requires SR-22 proof of insurance for three years plus a $40 reinstatement fee.
  • Points accrue per violation (80 for reckless driving, 35-75 for speeding, 60 for following too closely, 50 for a red light/stop sign/texting) -- 200+ points in 3 years (21+) or 70+ points in 3 years (under 21) triggers a hearing that can lead to suspension.
  • Half of accumulated points clear after one violation-free year, all clear after two; individual violation points also expire after three years, and a defensive driving course removes 50 points once every three years.
  • Driving on a denied, suspended, or revoked license means up to 90 days in jail plus a fine, and extends the original suspension/revocation by its own length -- a 3-month suspension becomes 6 months.

Child Passenger Safety

  • Children 8 and under (unless already 57 inches tall) need an approved car seat: rear-facing until age 2/30 lbs, then forward-facing with a harness until age 4/40 lbs, then a booster until the belt fits correctly and the child reaches 57 inches.
  • A driver can be cited for each unrestrained passenger, but police may only stop a vehicle specifically for a seat belt violation if an unrestrained occupant is under 16 -- occupants 16+ can only be cited if the vehicle was already stopped for another reason.
