Car Seat Laws in Washington

According to RCW 46.37.510, all children less than 16 years of age should be equipped with a safety belt system when transported in a motor vehicle, a medium-speed electric vehicle, or a neighborhood electric vehicle in operation.

Every driver must secure that the child is properly restrained in a passenger seating position according to the following conditions:

1. Children Below Two Years Old

A child who is less than two years of age must be properly secured with a rear-facing child restraint system until such time that he or she reaches the height and weight limit set by the manufacturer, as per recommendation by the American Academy of Pediatrics.

2. Children Two to Four Years Old

A child below four years of age and is not using a rear-facing child seat must be properly secured with a forward-facing child restraint system with a harness

This type of child restraint must be used until the child outgrown the system based on the manufacturer's standards.

3. Children Four Years Old and Older

A child four years old or older and under four feet nine inches tall must be properly secured in a child booster seat.

This can be used until such time that the vehicle lap and the shoulder belt fit the child correctly, which is between the age of eight to twelve years old.

- Backless booster seats

This type of seat should be used if the vehicle comes with proper headrests.

In case of a crash, the child's neck and shoulders must be protected with appropriate headrests or a full-sized booster seat with head protection.

- Booster seats with headrests

Vehicles without headrests should have a full-sized booster seat that includes headrests.

Keep in mind that children can suffer from severe injuries once the head and neck are not protected during an accident.

4. Seat Belts for Children

For children 13 years old or older, they are required to wear a seat belt, which both have a lap and a shoulder belt.

It should be worn properly as long as the vehicle is moving.


The child restraint system should comply with the standards set by the United States Department of Transportation.

It should also be secured in the vehicle according to the vehicle's manufacturer's instructions and the child restraint system's manufacturer.

Penalties for Violations

The penalty for getting pulled over for not wearing a seat belt or any appropriate child restraint system can be pretty steep.

A law enforcement officer can issue the driver a traffic citation, which may include a penalty of $112 or more for every child not wearing a proper restraint system.

However, instead of paying the ticket, this can be dismissed once the driver proves to have obtained an adequate child restraint system within seven days of ticket issuance.

If the driver already has a record and was issued a second ticket, then the second ticket will no longer be waived.

Consistent failure to wear a seat belt may result in the suspension of the license or even revocation, depending on the driver's number of offenses against the driver.

Are There Height and Weight Requirements in Washington?

There are really no height and weight requirements in Washington.

However, the following guidelines and recommendations should be followed:

- Children aged 0 to 2 must use a rear-facing car seat during travel.

- Children aged 2 to 4 must use a front-facing car seat during travel.

- Children aged 4 to 12 and having a height of 4'9" must use a booster seat with a seat belt.

- Children aged 13 and up must use a seat belt.

Additionally, Washington's state requires children 13 years and below to be seated in the motor vehicle's rear seat.

Are There Exemptions to the Car Seat Laws of Washington?

There are certain exemptions to Washington's Car Seat Laws.

Still, they apply only to vehicles such as taxis, buses, school buses, limos, large passenger vans, and company vehicles, which are operated by workers.

Vehicles who need to make frequent stops, such as those that deliver packages and postal mail, are also exempted from the law.

Are there rules for children with medical conditions?

If a child has a medical condition that stops him or her from using a car restraint system, then it is a must to carry documentation signed by a physician in case a police officer pulls over your vehicle.
