A bill for an act relating to the use of child restraint devices by certain children traveling in motor vehicles.

This bill updates Iowa's child passenger safety requirements. It extends the rear-facing car seat requirement from children under 1 year to those under 2 years (or until reaching the car seat's height/weight limits). It raises the age for forward-facing car seats from under 6 to under 8 years, and changes the requirement for booster seats or seatbelts to apply to children aged 8-18 (instead of 6-18). The bill removes an existing exemption allowing unrestrained children in the back seat if seatbelts are occupied by others. The rules apply to all registered motor vehicles except school buses and motorcycles.
