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 theirjob when you're reclined like this. a The shoulder belt can't do its job. Incrash you could go into it, receiving neck or otherinjuries. 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 could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly.
