Washington State Rear-Facing Car Seat Law (0-2 years)

Rear- Facing Car seat law

Rear-facing car seats are convertible seats or infant seats that face the back of the car.

The rear-facing position is important for the infant babies whose spinal cord is not ossified. 

That means their spinal cord is not turned to bone from cartilage.

Washington law requires children under the age of 2 to travel in the rear-facing car seat. 

Rear-facing seats need to be federally approved and placed in the back of the car seat.

UW Medicine also states that Children should remain in a rear-facing car safety seat as long as possible until they reach the highest weight or height allowed by their seat.

Washington state  Forward-facing Car Seat Law (2-4 years)

Forward-facing car seat

Forward-facing car seats face the front of the vehicle. When a child outgrows a rear-facing car seat, it is time to change their seat into a forward-facing car seat. 

A rear-facing car is always considered safer for children under two years than a forward-facing car seat. 

Washington Child restraint law requires a child between 2 and 4 years old to be seated in a car seat with a harness seat regardless of a rear or forward-facing car seat.

Seat belt

A child passenger cannot be fit in an adult car seat and seat belt. That’s why it is important to ensure the right car seat and proper seat belts according to the state’s law about child passenger safety.

However, you can easily determine if your child is ready to fit in a car seat belt by answering a five-question test.

These questions are –

● Does your child sit all the way back against the car seat?
● Can your child bend his knees comfortably at the edge of the car seat without slouching?
● Does the seat belt cross your child’s neck and arm?
● Does the lap belt touch their thighs as low as possible? 
● Is your child able to sit in the same position the whole trip?

If the answer to any of these questions’ replies is “no,” then you should still use a booster seat for your child. If all the answers are “yes,” then they are ready to use the car seat belt.
