Idaho law requires all vehicle passengers to wear seat belts but additionally requires special restraints for children so as to reduce vehicle-related injuries. The proper restraint might be a forward-facing or rear-facing car seat or booster seat, depending on the child's height, weight, and age. Failure to use the right kind of car seat or seat belt can result in fines and fees.
All Idaho children who are six years old or younger must be properly secured in a child safety restraint. While Idaho law does not specify the specific seat to be used, the Idaho Department of Transportation has published the following recommendations. (Idaho Code Ann. § 49-672 (2024).)

Failure to properly secure a child who's under seven years old will result in an $84 fine. Some judges might be willing to waive the fine and conviction if the cited driver obtains a proper child restraint system.
Rear-facing car seats are generally appropriate for infants who are younger than two years old and children who are up to four years old but weigh less than 40 pounds.
Forward-facing car seats are typically appropriate for children who are at least two years old and weigh at least 40 pounds. Normally, the child should continue to use the forward-facing seat until they outgrow the manufacturer's recommendations.
Children who are at least seven years old aren't required to use a child restraint system. But the state encourages children to remain in a booster seat until they are at least 40 pounds and four feet, nine inches tall.
At the very least, all passengers must wear a safety belt. A violation will result in the driver receiving a fine of up to $66.50.
