But don't have a seatback reclined if your vehicle is moving. Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their jobwhen you're reclinedlike this. The shoulderbelt can'tdo its job because it won't beagainst your body. Instead, it will be in front of you. In a crash you could go into it, receiving neck or other injuries. The lapbelt can't do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This couldcause serious internal injuries. For proper protection when the vehicle is in motion, havethe seatback upright. Then sit well back in the seat and wear your safety belt properly.
