The safest place for an infant car seat is in the back seat, specifically in the center. This position provides the best protection by maximizing the distance from any potential side-impact collisions. If the center seat isn't feasible due to vehicle design or a tight fit, the rear seat behind the passenger side is the next safest option.
This recommendation is supported by extensive research. A study published in the journal Pediatrics found that children under 3 years old are 43% less likely to be injured in a crash when seated in the center of the rear seat compared to either side. The primary reason is the increased "crush zone," or the space between the child and the point of impact.
Here’s a quick comparison of rear seat positions:
| Position | Key Advantage | Primary Consideration |
|---|---|---|
| Center Rear | Maximum distance from side impacts. | May not be compatible with some vehicle seat belts or LATCH systems. |
| Rear Passenger Side | Easier for a parent to see and reach the child from the driver's seat. | Closer to potential passenger-side impacts. |
| Rear Driver Side | Convenient for curbside drop-off. | Least recommended for infants; furthest from the caregiver's view. |
Never install a rear-facing infant seat in the front passenger seat, especially if the airbag is active. The force of a deploying airbag can cause severe injury or be fatal to a child. Always deactivate the passenger airbag if you have no other choice but to use the front seat—consult your vehicle's owner's manual for instructions.
To ensure a correct installation, use either the vehicle's LATCH system (Lower Anchors and Tethers for Children) or the seat belt, but not both simultaneously unless the car seat manufacturer explicitly permits it. The key is to achieve a secure, tight fit; the car seat should not move more than one inch side-to-side or forward at the belt path. Many local fire stations or police departments offer free car seat installation checks—it's a valuable resource for peace of mind.

As a new mom, I was obsessed with getting this right. Everyone told me the middle of the back seat is safest, and that’s where we put ours. It just makes sense—it’s farthest from any doors that could get hit. But honestly, what really sold me was putting it behind the passenger seat. I can quickly glance back at a red light to check on her without taking my eyes completely off the road. That little bit of reassurance is huge when you're driving alone.

From a safety engineering standpoint, the center rear is optimal. It minimizes the risk in side-impact collisions, which are particularly dangerous. The vehicle's structure provides the most protection in this location. The second-best choice is the rear passenger side. This allows the driver to safely attend to the infant without exiting the vehicle onto traffic. The front seat is not an option due to airbag deployment risks. Always prioritize a proper installation above all else.

Let's be practical. The absolute safest spot is the center of the back seat, no question. But you have to live with it. If you drive a smaller car, a rear-facing seat might not even fit securely in the middle. In that case, the seat behind the passenger is your best bet. It's safer than the driver's side for the kid, and you can still reach back to hand them a pacifier without climbing into the car. The goal is the safest practical position for your specific vehicle.

I remember the technician at the fire station explaining it like this: think of your car as a target. The center of the back seat is the bullseye—it’s the farthest point from any edge. That’s where you want your most precious cargo. A proper installation is more important than the exact position, but if you can get that bullseye spot, you’ve won. We tried the middle first, but in our SUV, we got a tighter fit using the LATCH anchors on the passenger side. So we went with that. It’s all about what gives you the most secure installation.
