When in the car, always wear your seat belt. During pregnancy, wear the seat belt below your pregnant abdomen, not above it. Keep the shoulder strap in its usual position. Mom not wearing a seat belt is a greater hazard to the fetus than if she wears it.
Auto accidents are dangerous events.
Injury to the mother directly affects the well-being of the fetus. Take steps to be safe. Get out of the car and walk around. Empty your bladder. Remember to keep drinking fluids throughout the trip, even though it may mean extra stops.
