These are much more conservative than state laws, in general (for instance, everyone should be in a booster seat from about age 4 to at least age 8) but remain less conservative than some of the european standards (for instance, the European Child Safety Alliance recommends that children remain in rear-facing carseats until 3 years of age).

Children between 2 and 4 must ride in a car seat with a harness. Children between 4 and 8 must be in a car seat or booster unless they are taller than 4-foot-9.
