How long must a child remain in a car seat?

All children riding in passenger motor vehicles must be in a federally approved child passenger restraint that is properly fastened and secured according to the manufacturer's instructions until they are 8 years old OR over 57 inches tall.

When children outgrow their booster seats (usually around age 8, but more importantly, when they are taller than 57 inches), they must wear a seat belt that is properly adjusted and fastened according to the manufacturer's instructions until the age of 13.
