Safety Belt Use During Pregnancy Safety belts work for everyone,including pregnant women. Like all occupants, they are morelikely to be seriously injured if they don't wear safety belts. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle. A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy. 1-30
