Driving while pregnant: seat belts, air bags and when to see a doctor
How to wear your seat belt, set up your seat and stay safe while pregnant
Most pregnant people keep driving and riding in cars for most of their pregnancy. That is normal. But a growing belly changes how a seat belt fits and how close you sit to the steering wheel and air bag. A few adjustments make a big difference.
The stakes are real. A University of Pittsburgh study published in JAMA looked at fetal deaths linked to injuries to the mother. Motor vehicle crashes were the leading cause, accounting for 82 percent of cases where the cause was listed [1]. The researchers estimated more than 369 fetal deaths a year from crashes, and they believed the true number was higher [1].
How to wear your seat belt
The Children’s Hospital of Philadelphia gives clear guidance [2]:
- Use both parts of the belt. A lap and shoulder belt together is the safest choice.
- Lap belt low. Place it below your belly, over your upper thighs and snug against your hip bones.
- Never across the belly. Do not wear the lap belt above or across your bump.
- Shoulder belt across the chest. It should cross the center of your chest, between your breasts, and over your shoulder. Never put it under your arm or behind your back.
- Snug, not loose. Remove slack from the belt.
Be careful with add on belt positioners sold for pregnancy. They are not held to federal crash standards. Ask your doctor before using one.
Set up your seat
As the driver:
- Move your seat back as your belly grows. Keep at least 10 inches between your breastbone and the steering wheel [2].
- Tilt the steering wheel toward your chest, not your belly, if it adjusts.
- Make sure you can still reach the pedals easily and see over the wheel.
As a passenger:
- Ride in a seat with a lap and shoulder belt.
- Move the front passenger seat back as far as it goes, or ride in the back.
Should I turn off the air bags?
No. Air bags work with seat belts to protect you. Keep them on, and keep your distance from them [2].
Comfort and safety on the road
- Take breaks every hour or two on long drives to stretch and walk. This helps circulation.
- Keep snacks and water handy if nausea or low blood sugar is a problem.
- Do not drive if you feel dizzy, faint or very tired. Pregnancy can bring sudden fatigue.
- Avoid long solo trips late in pregnancy. Know where hospitals are along your route.
- Do not drive yourself to the hospital in labor. Have a plan for a ride.
After any crash: get checked
Even a minor crash can cause problems that you cannot feel right away, such as a separation of the placenta. Call your doctor or go to the hospital after any crash, even if you feel fine.
Warning: Go to the hospital or call 911 right away after a crash if you have belly pain, cramping, bleeding or fluid leaking from the vagina, a change in your baby’s movements, or contractions. Tell the medical team you are pregnant.
Late pregnancy
There is no set week when pregnant people must stop driving. Stop when you can no longer sit 10 inches back and still reach the pedals safely, when you are too uncomfortable to focus, or when your doctor advises it.
Checklist: pregnancy car safety

- I always wear a lap and shoulder belt
- My lap belt sits low, under my belly and across my hips
- My shoulder belt crosses the middle of my chest
- My breastbone is at least 10 inches from the steering wheel
- My air bags are on
- I know to call my doctor after any crash, even a small one
- I have a plan for getting to the hospital in labor
Frequently asked questions
Is it safe to drive in the third trimester?
Many people drive until near their due date. Make sure you can sit back safely, reach the pedals and turn to check blind spots. Ask your doctor about your situation.
Can a seat belt hurt my baby in a crash?
A properly worn belt, with the lap part under your belly, is much safer than no belt. The greatest risk to a baby comes when the mother is hurt or thrown in a crash.
Should I sit in the back seat?
The back seat is generally safer for everyone. If you ride in front, move the seat back and keep the air bag on.
