Baby's first ride home: car seat safety for newborns
How to choose, install and buckle a car seat for your newborn's first trip home
The first ride home is a milestone. It is also the first of thousands of car trips your child will take. Getting the car seat right from day one protects your baby and builds habits that last.
Car seats work, but only when they are used correctly. A national NHTSA study found that 46 percent of car seats and boosters were misused in ways that could reduce protection [1]. This guide walks you through the basics for a newborn.
Before the baby arrives
- Choose a rear facing seat. Newborns ride rear facing, in either an infant only seat or a convertible seat that starts rear facing. Check that the seat’s weight and height range fits a newborn.
- Install it early. Put the seat in your car at least a few weeks before your due date. Babies do not always wait.
- Use the back seat. The center of the back seat is often a good spot if you can install the seat tightly there. Follow both the car seat manual and your vehicle manual.
- Get it checked. Certified child passenger safety technicians check seats for free in many communities. NHTSA has a car seat inspection station locator [2].
- Register the seat with the maker so you hear about recalls.
Installation basics
- Use either the lower anchors (often called LATCH) or the seat belt to install, not both, unless the seat maker says you can.
- The seat should move less than 1 inch side to side or front to back when you tug it at the belt path.
- Set the recline using the seat’s level indicator, so the baby’s head does not flop forward.
- Never place a rear facing seat in front of an active air bag [2].
Buckling your newborn
Harness height. For rear facing seats, the straps come from slots at or just below your baby’s shoulders.
Snug straps. After buckling, try to pinch the strap at the shoulder. If you can pinch a fold of webbing, tighten it.
Chest clip. Place it at armpit level.
No bulky clothes. Thick coats and snowsuits compress in a crash, leaving the harness too loose. Dress your baby in thin layers, buckle them in, then put a blanket over the straps.
No extras. Avoid inserts, head supports, strap covers or toys that did not come with the seat. They have not been crash tested with it.
Premature and medically fragile babies
Babies born before 37 weeks usually need a car seat tolerance screening before going home [3]. Hospital staff watch the baby’s breathing, heart rate and oxygen level while sitting in the car seat. Some babies need a special car bed for a while. Follow your care team’s instructions.
The drive home
- Ask a rested adult to drive. New parents are often exhausted.
- Have another adult ride in back with the baby if possible.
- Keep the trip simple. Go straight home.
- If the baby needs attention, pull over safely. Never take a baby out of the car seat while the car is moving.
Warning: Car seats are for travel, not for sleep outside the car. If your baby falls asleep in the car seat, move them to a firm, flat crib or bassinet once you arrive. Babies can slump and have trouble breathing in sitting devices.
The American Academy of Pediatrics recommends that sitting devices, including car seats, not be used for routine sleep [4].
A new federal standard for car seats
Starting December 5, 2026, newly made car seats must pass a federal side impact test [5]. Seats you already own do not need to be replaced because of this rule, as long as they are not expired, damaged or recalled. When you shop, you can ask whether a seat is certified to the new side impact standard.
Checklist: ready for the ride home

Frequently asked questions
Can I use a secondhand car seat?
Only if you know its full history. Do not use a seat that has been in a moderate or severe crash, is expired, is missing parts or labels, or has an open recall.
How long should my baby stay rear facing?
As long as possible, until they reach the highest weight or height allowed by the seat’s rear facing limits.
Will the hospital check my car seat?
Some hospitals check, and some do not. Do not count on it. Have it checked before the baby arrives.
