As for when the child should be allowed to sit in the front seat, the laws do vary state by state, but the CDC suggests that all children ages 12 and under sit buckled in the back seat. Airbags can actually be dangerous for young children and sitting in the front seat could be fatal. Usually, by the age of 12-14 the child is at a height (4 feet 9 inches) where the airbag is no longer a safety hazard. When your child is at a height where they can sit in the front seat, make sure they know how to properly wear their seatbelt before moving the vehicle. It’s especially important to note that using a seatbelt is always necessary to ensure safety while in a vehicle and the best way to set a good example for children is to always wear a seat belt when you’re in the car.
