AAP guidance is a safety best practice and is separate from Guam’s legal minimum. Guam requires a car seat only through age 3 and sets no rear-facing rule, so pediatric guidance goes well beyond the statute.

Frequently asked questions

What is the car seat law in Guam in 2026?
A child under 4 must ride in a child passenger restraint system. A child 4 to 11 who is under 4 feet 9 inches must ride in a booster or fitting restraint, and everyone else must wear a seat belt.
Is the Guam car seat law changing?
No. As of August 1, 2026, when SeatChecker last checked the statute, no enacted change to the Guam car seat law is scheduled. Current law: A child under 4 must ride in a child passenger restraint system. A child 4 to 11 who is under 4 feet 9 inches must ride in a booster or fitting restraint. Everyone else must wear a seat belt. Guam law sets no rear-facing or back-seat requirement.
What age can a child sit in the front seat in Guam?
Guam law sets no minimum age for riding in the front seat. The child restraint rules still apply: a car seat or booster is required until age 12 or 4'9". The American Academy of Pediatrics recommends the back seat for all children under 13. That is best practice, not a legal requirement in Guam.
When can my child stop using a booster in Guam?
At age 12, or earlier once the child reaches 4 feet 9 inches. Pediatricians recommend keeping a child in a booster until the seat belt fits properly.
Does Guam require rear-facing car seats?
Guam law does not set a rear-facing age. It requires a child under 4 to be in a child restraint, and a child 4 to 11 who is under 4 feet 9 inches to use a booster or fitting restraint. Pediatricians recommend keeping a child rear-facing as long as the seat allows.
Are taxis exempt from Guam's car seat law?
Yes. Guam exempts taxis, buses, and emergency vehicles from the child restraint requirement. The safety recommendation to use a car seat or booster still applies whenever one can be used.
