Having tested car seats in every configuration imaginable, I know that Utah’s child restraint law stands out for its simplicity — children under 8 must be properly restrained, period. But with 115 unrestrained children involved in Utah crashes in a single year, too many families still aren’t getting the message.
Utah recorded 281 traffic fatalities in 2024, with 39% of crash victims unrestrained. The state’s 92.4% seat belt use rate is among the highest in the nation, but that still leaves thousands of rides where children may not be properly secured.
This guide covers everything Utah parents need to know about car seat requirements under Utah Code 41-6a-1803, from infant seats through the booster seat transition.

Utah car seat laws by age
Rear-facing car seats: Utah law requires children under 5 years old to be secured in a child restraint device. While the statute doesn’t specify rear-facing separately, NHTSA and the AAP recommend keeping children rear-facing until at least age 2, or until they reach the maximum height and weight limits of their rear-facing seat. For best protection, keep your child rear-facing as long as possible.
Forward-facing car seats: Children under 5 must be in a child restraint device appropriate for their age and size. Once your child outgrows their rear-facing seat, they should move to a forward-facing harnessed car seat. Most children remain in a forward-facing seat with harness until around age 4 and 40 pounds, at which point they can transition to a booster.
Booster seats: Under Utah Code 41-6a-1803, children ages 5 through 7 must be secured in a child restraint device or booster seat. The booster seat requirement continues until the child turns 8 years old. Safety experts recommend keeping children in a booster until they are at least 4 feet 9 inches (57 inches) tall, regardless of age, because the seat belt needs to fit properly across the chest and lap.
Seat belt: Children 8 years and older through age 15 must wear a seat belt. Utah’s seat belt law covers all vehicle occupants, and children who have outgrown the booster requirement must still be properly restrained with a lap and shoulder belt.
Back seat recommendation: Utah safety officials recommend children ride in the back seat until age 13. While this isn’t a legal requirement, the back seat is statistically the safest position in the vehicle for children.

Fines and enforcement
Utah treats child restraint violations as infractions:
The maximum fine for a car seat or seat belt violation is $45.
Fine waiver options: Utah offers two ways to reduce or eliminate the fine:
- Safety course: Complete a two-hour child passenger safety course approved by the Department of Public Safety, and the court will waive all but $15 of the fine.
- Car seat purchase: For a first-time child restraint violation, submit proof that you purchased, rented, or acquired a child restraint device, and the court will waive the entire fine.
Utah has primary enforcement for child restraint violations, meaning officers can stop you solely for an unrestrained child passenger.
No points are assessed on your driving record for a child restraint or seat belt violation under this section.
Special situations
Taxis and rideshares: Utah’s child restraint law applies to all motor vehicles operated on public highways. When using Uber, Lyft, or a taxi, parents are still required to properly restrain their children. Bring your own car seat or consider a portable travel seat for rideshare trips.
Vehicles without back seats: If your vehicle doesn’t have a rear seat, children may ride in the front seat with appropriate restraints. Deactivate the front passenger airbag when using a rear-facing car seat in the front.
Leaving a child unattended: Utah law makes it a class B misdemeanor to leave a child under 9 years old unattended in a vehicle if conditions could endanger the child’s health or safety.
Smoking in vehicles: Utah prohibits smoking in vehicles when a child under 15 is present.
Crash replacement: Replace any car seat involved in a moderate-to-severe crash, even without visible damage. Many manufacturers provide free replacements, and insurance policies often cover the cost. For more information, see our guide on what to do with old car seats.
What to do if you get a ticket
If you receive a child restraint citation in Utah, here’s your action plan:
1. Get a car seat to waive the fine. For a first offense, purchase or acquire an appropriate child restraint device and present proof to the court. The entire fine will be dismissed.
2. Take a safety course. Complete an approved two-hour child passenger safety course to reduce your fine to just $15. This course also teaches proper installation techniques.
3. Find free car seat resources. Utah has programs that provide free or low-cost car seats through local health departments and community organizations. Visit our free car seats in Utah page for a full list of programs. You can also find a certified technician to check your installation at the NHTSA car seat inspection locator.
