Virginia's Child Safety Seat Laws
As of July 1, 2019: Children are to ride in a rear-facing safety seat until the age of two or the child reaches the minimum weight limit for a forward-facing safety seat as prescribed by the manufacturer of the safety seat.
Child restraint devices are required for children through the age of seven (until 8th birthday). Safety seats must be properly used and approved to meet Department of Transportation standards. The Virginia law is based on age and proper usage. Proper selection and use of a safety seat regarding weight and height is in accordance with the instructions of the manufacturer of the safety seat. Rear-facing child restraint devices must be placed in the back seat of a vehicle. In the event the vehicle does not have a back seat, the child restraint device may be placed in the front passenger seat only if the vehicle is either not equipped with a passenger-side airbag or the passenger side airbag has been turned off.
