Idaho Booster Seat Laws


There’s no specific booster seat law in the state of Idaho. The only reference is that below the age of 6, the car seat is mandatory, and above it, you can use the seat belt.

Now, if you want to be extra cautious, I highly recommend keeping your child in the booster seat until they reach 57 inches. This way, you know they are safe.


Idaho Rear-facing Car Seat Laws

Again the law is quite broad, so if you want to keep your little one safe, make sure you keep them rear-facing as long as possible. Typically 2 years of age is the first time you should consider moving them in a forward-facing position; however the longer they are in rear-facing the safer they are.

Also, besides looking at their age always check the weight and height limit of the car seat and adjust accordingly.


Idaho Forward-facing Car Seat Laws

Forward-facing can be used after the age of 2 or after the rear-facing seat has been outgrown either in weight or height.

I can’t stress this enough the longer you’re having your kids in rear-facing mode, the safer they are.


Idaho Taxi Car Seat Laws

The car seat laws are for non-commercial vehicles. So taxis in the state of Idaho are exempt from the car seat laws; this includes ride-sharing services.

If you want to be on the safe side, then make sure you bring your car seat because you never know.


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

There’s no current law saying when a child can sit in the front. Experts from the Idaho Transportation Department recommend that only those kids should be sitting in the front who can comfortably use the seat belt, and this happens around the age of 12-13.
