Do any rules apply to installing a child seat?

Child seats can only be installed in the back seat. They can't go in the front.

Guam law requires a seat that fits your child's age and weight: an Infant Seat from birth to age 1 (up to 9 kg), a Child Seat for ages 1 to 4 (9 to 18 kg), and a Booster Seat for ages 4 to 11 (up to 144 cm tall). For prices, see the Options page.

*You'll need to install the seat yourself. When you return the car, please take the seat out and bring it back to the counter. How many seats fit in one car depends on the vehicle class.
