LATCH is a new system that makes child safety seat installation easier without using seat belts. LATCH is required on most child safety seats and vehicles manufactured after September 1, 2002. LATCH is not required for booster seats, car beds and vests.
The National Highway Traffic Safety Administration has information available regarding the new LATCH system for child safety seats. To learn more, visit
