Utah Car Seat Laws 2023

Utah has implemented new car seat laws to ensure the protection of infants, toddlers, and young children. These updated regulations aim to provide clearer guidelines for parents and guardians, helping them make informed decisions when it comes to choosing and correctly installing car seats. Understanding and adhering to Utah Car Seat Laws is crucial for ensuring the safety of our children on the roadways.

Utah Car Seat Requirements

Under the new Utah Car Seat Laws, children under the age of 8 are required to be properly secured in a car seat or booster seat appropriate for their age, weight, and height. Children who have reached 8 years old but are still shorter than 57 inches must also be restrained in an appropriate child restraint system. The law requires rear-facing car seats for infants and toddlers until the child reaches at least 2 years of age or exceeds the height and weight limitations specified by the car seat manufacturer.

Child Booster Seat Laws in Utah

In Utah, children who are at least 8 years old but are shorter than 57 inches are required to ride in a booster seat until they reach the height of 57 inches. A booster seat helps position the seat belt correctly over the child’s body, offering additional protection in case of a crash. It is vital to choose a booster seat that is appropriate for the child’s weight and height, and to always follow the manufacturer’s instructions for proper installation.

Leaving Child in Car Law in Utah

Utah has strict laws in place regarding leaving children unattended in vehicles. It is illegal to leave a child under the age of 9 in a motor vehicle without supervision if the conditions present a substantial risk to the child’s health or safety. These conditions may include extreme heat or cold, lack of ventilation, or any other circumstances that may endanger the child’s well-being. Violation of this law can result in criminal charges and penalties.

Taxi Car Seat Law in Utah

When it comes to taking a taxi or a private hire vehicle in Utah, the state provides an exemption from the car seat laws for children under the age of 8. However, this exemption does not mean compromising child safety. Parents and guardians are strongly encouraged to bring and use an appropriate child restraint system in taxis and private hire vehicles whenever possible. Whenever feasible, the best practice is to provide a car seat or booster seat suitable for the child’s age, weight, and height.

Seat Belt Laws in Utah

Utah follows the primary enforcement seat belt law, meaning law enforcement officers can stop and ticket drivers solely for not wearing their seat belts. The law requires all drivers and front-seat passengers to wear seat belts. It is also mandatory for all passengers under the age of 18 to be secured by a seat belt or a child restraint system, regardless of the seating position in the vehicle. Seat belts save lives, and everyone in the vehicle must make sure to buckle up for their own safety.

Utah Ridesharing Child Seat Law

Utah law requires ridesharing companies, such as Uber and Lyft, to provide and use appropriate child restraint systems for passengers under the age of 8. The responsibility of providing a car seat or booster seat falls on the rideshare company or driver. Passengers are encouraged to inform the ride-hail driver in advance if a child will be traveling with them and requires a child restraint system. This law ensures the safety of young passengers when using ridesharing services.

Utah Child Seat Replacement Law

Utah law recommends replacing child car seats after any crash, regardless of the severity. This precautionary measure helps ensure that the structural integrity of the seat has not been compromised, even in minor accidents that might not be immediately apparent.

It is crucial to follow the manufacturer’s instructions and contact the seat manufacturer to determine if a replacement is necessary. Prioritizing the safety of our children means taking every necessary step to provide them with the best protection possible.

Utah Car Seat Laws


Are car seats effective?

Car seats are highly effective in protecting children during car accidents or sudden stops. They are specifically designed to reduce the risk of injury by providing a secure and padded seating position for children of different age groups and sizes. The use of car seats has been proven to reduce the risk of fatal injury for infants by about 71% and for toddlers by 54% in the United States.

When Can My Child Sit in the Front Seat in Utah?

In Utah, the law states that children under the age of 8 must be properly secured in an appropriate car seat or booster seat. Additionally, children who are at least 57 inches tall or weigh at least 80 pounds may use seat belts without a booster seat. It is important to follow these guidelines, as they are in place to ensure the safety of children in vehicles.

Is it Illegal to Smoke in a Car with a Child in Utah?

Yes, it is illegal to smoke in a car with a child in Utah. The Utah Child Passenger Restraint Law prohibits smoking in a vehicle when a child who is younger than 15 years old is present. This law aims to protect children from exposure to secondhand smoke, which can cause numerous health problems and is particularly harmful to their developing lungs.

What Car Seat Should A 4-Year-Old Be In?

A 4-year-old should be placed in a forward-facing car seat with a harness. The American Academy of Pediatrics (AAP) recommends using a car seat with a five-point harness for as long as possible until the child reaches the height and weight limits specified by the manufacturer. These guidelines may vary depending on the specific car seat model, so it is essential to refer to the manufacturer’s instructions for the appropriate size and weight limits.

Can A 4-Year-Old Sit In A Booster Seat?

Yes, a 4-year-old can sit in a booster seat, but only if they meet the minimum weight and height requirements set by the manufacturer. Booster seats are intended for children who have outgrown their forward-facing car seats but are still too small to use a vehicle seat belt alone. It is essential to choose a booster seat that provides proper belt positioning and have the child use it until they meet the recommended height and weight requirements for seat belt usage without a booster.

How Long Are Car Seats Good For?

The lifespan of a car seat depends on several factors, including the manufacturer’s guidelines, the specific model, and the condition of the seat. Most car seat manufacturers recommend using their seats for around 6 to 10 years, although some may extend this period.

It is crucial to check the manufacturer’s instructions and labels on the car seat itself for the specific expiration date, as using an expired car seat can compromise its safety features and effectiveness. Additionally, car seats should be replaced if they have been involved in a moderate to severe crash, show signs of damage or wear, or if they no longer meet the current safety standards.



With the implementation of the Utah Car Seat Laws in 2023, the state has taken significant steps toward prioritizing child safety in vehicles. By understanding and abiding by these laws, parents, guardians, and drivers can play an active role in protecting our most precious passengers. Remember, the safety of children should always be a top consideration, and complying with car seat requirements and laws is a vital aspect of responsible driving.
