What are Idaho Car Seat Laws?

Things to remember...

  • The car seat law in Idaho is a primary law
  • The Idaho child restraint law does not offer specific guidelines regarding when to turn a car seat from rear-facing to front-facing
  • The AAP offers guidelines that Idaho drivers can follow for additional safety on the road
  • Car insurance companies in Idaho will enforce their own policies on following these safety precautions


Drivers in Idaho must take appropriate steps to keep children as safe as possible on the road. There are laws in Idaho regarding the proper use of car seats for younger children as well as seat belts for older children.

However, some drivers also refer to the American Academy of Pediatrics, or AAP, for clarification about the proper and safe use of car seats.

The AAP is a highly respected, national organization, and its recommendations apply to the general use of car seats and seatbelts. It recommends that drivers use rear-facing car seats in the backseat of the car for all children who are two years old or younger.

The AAP also recommends that front-facing car seats be used for children between the ages of two years old and eight to 12 years old who are less than 57 inches tall. There are no weight guidelines offered by the AAP for the safe use of car seats versus adult seat belts.

What are the Idaho Child Restraint and Booster Seat Legal Requirements?

Idaho’s Child Safety and Seatbelt Laws

The child car seat law in Idaho provides minimum legal requirements for the use of car seats that must be met, and this is unlike the AAP’s guidelines, which are recommendations.

Safety Restraints for Children Under Seven Years Old in Idaho

The Idaho car seat law requires any child who is under the age of seven years old to be secured by a car seat.

This law does not provide requirements for the use of a front-facing car seat versus a rear-facing car seat, and it does not provide recommendations for the use of car seats based on height or weight.

With this in mind, it is recommended that drivers in this state closely follow the AAP guidelines for child restraints to keep children in their vehicles as safe as possible.

What are the Height and Weight Requirements for a Booster Seat for Children Over Seven Years Old in Idaho?

While Idaho law does not specify how long children must ride in a booster seat, for safety it is encouraged that a child use a booster seat in Idaho until weighing 40 lbs. minimum and reaching a height of 4’9″. At the age of 7, a child is not required to use a booster seat.

At the recommendation of the Idaho Transportation Department, a child, from the ages of 4-8, should ride in a backless belt-positioning booster seat. They should also stop using it when they are 4’9.”

What are Idaho Seatbelt Laws for Adults?

The adult seat belt law in this state is secondary, which means that law enforcement officials will need another primary reason to pull you over and cannot pull you over simply because you were not wearing your seatbelt.

For example, they may pull you over for speeding, and they can then charge you for a seat belt law violation.
