Requires children under age 2 to be secured in a rear-facing child passenger restraint system, with an exception allowing forward-facing when the child exceeds the manufacturer's rear-facing weight or height limits

Adds a new requirement that children under age 4, regardless of weight, must be secured in an appropriate child passenger restraint system

Children ages 4-7 who weigh 40-79 pounds and are under 4 feet 9 inches tall must use a child passenger restraint system or booster seat

Children who reach 80 pounds, 4 feet 9 inches in height, or age 8 may transition to a standard vehicle safety belt
