Car seat safety & installation tips

Car crashes remain the no. 1 cause of death for children ages 1-12, and children who aren't properly secured in their car seats are at high risk of being severely injured. Practicing child passenger safety and knowing how to correctly install a car seat is essential to help reduce injuries.

According to the U.S. Department of Transportation’s National Highway Traffic Safety Administration, 46% of car seats are installed incorrectly. To help ensure your kids are as safe as possible in the car, follow our child safety seat installation tips and recommendations.

What to know before installing your car seat

Every car seat & vehicle is different

To properly install your car seat, read the instructions for the child safety seat and the vehicle owner's manual.

The car seat should also fit in your vehicle, and be used correctly for every car ride.

Kids under 13 should ride in the back seat

Until your child is a teenager, the safest place for them to sit in your vehicle is in the rear seat.

Car seat installation tips

According to research, child safety seats can reduce deaths by up to 71% for infants, and 54% for toddlers ages 1-4.1 There are 2 ways to properly secure a car seat: with the seat belt or with lower anchors (also known as Lower Anchors and Tethers for Children, or LATCH for short). Unless you have one of the few car seats that specify you can get a safe installation when both methods are used, you shouldn't use them at the same time. Read our installation tips to help get a snug fit.

Route the seat belt through the correct belt path of the car seat and buckle it.

Installing your car seat with a vehicle seat belt

  • Identify how to "lock" your vehicle seat belt. A "locked" seat belt will not extend when pulled and restrains you in the event of a crash. Beginning with model year 1996 vehicles, passenger seat belts in the U.S. must have a switchable retractor that can be turned to an always-locked mode.
  • Route the vehicle seat belt through the correct belt path of the car seat and buckle it.
  • Firmly press the car seat down while tightening the seat belt. Make sure to activate the locking mechanism of the vehicle seat belt.
  • Tether the car seat if instructed to do so by the manual.
  • Check the car seat installation. Your car seat shouldn't move more than 1 inch side-to-side from the belt path.

Lower Anchors and Tethers for Children (LATCH) is an alternate attachment system.

Installing your car seat with lower anchors

  • Locate your vehicle’s lower anchors by reading your owner's manual and look for the latch symbol on the rear seat of the vehicle.  
  • Route the car seat’s lower anchor attachments through the correct belt path of the car seat.
  • Fasten the car seat’s lower anchor attachments to the vehicle’s lower anchors.
  • Firmly press the car seat down while tightening the car seat’s lower attachments.
  • If installing the car seat forward-facing, attach the car seat’s top tether hook to your vehicle’s tether anchor and pull to tighten. See the vehicle owner's manual for the location of the tether anchor.
  • Follow the labels or diagrams on your car seat for weight limits on the lower anchors.

NOTE: Most rear-facing car seats don’t use tethers.

Types of car seats

The way your child can safely ride in your car will change as they will eventually outgrow their car seat and need a new one, but it's important to remember not to transition your child too soon. Most parents will need 3 types of child safety seats as their child grows: a rear-facing car seat, a forward-facing car seat, and a booster seat. 

We look at the differences between the types of car seats, the child age and/or weight recommendations, and how to properly secure your child in the seat.

Children 2 and under should ride in rear-facing car seats unless they are 40 pounds or more or 40 inches or taller.

Rear-facing car seats

Rear-facing only car seat

For children 2 and under, weighing up to 35 pounds. Also called an infant carrier, this seat is specially designed for newborns and babies, and can only be used rear-facing. 

Rear-facing convertible car seat

For children 2 and under, weighing up to 45 pounds. As the name suggests, this car seat can be converted to be forward-facing as your child grows.

Rear-facing car seat use tips

  • Protect your child’s neck and spinal cord by using a rear-facing car seat until age 2 or until they reach the maximum weight or height of the car seat.
  • Never install a rear-facing car seat onto the front seat of a vehicle with an active airbag.
  • Your child’s head should be 1 inch below the top edge of the car seat.
  • Keep the harness straps snug at or below your child’s shoulders. You shouldn’t be able to pinch the fabric above the harness clip.
  • Place the harness clip at your child’s armpit level.
  • Check the car seat’s level indicator for the proper angle.

Forward-facing car seats

Forward-facing convertible car seat

For children weighing up to 80 pounds. This type of seat should be rear-facing until your child reaches the height and weight limit for rear-facing use. It then can be changed to forward-facing using a harness and tether.

Combination booster seat (with internal 5-point harness)

For children weighing up to 85 pounds. Also known as a harness-to-booster seat, this uses an internal 5-point harness to restrain your child, but can be converted to a booster seat that uses your car's seat belt once your child outgrows the height and weight limit. 

Forward-facing car seat use tips

  • Route harness straps through forward-facing slots at or above your child’s shoulders.
  • Keep harness straps snug on your child. You shouldn’t be able to pinch the fabric above the harness clip.
  • Place the harness clip at your child’s armpit level.
  • Recline stand should be in the upright position.
  • The top tether hook should be attached to the vehicle’s tether anchor.

Booster seats

High-back booster

For children weighing up to 120 pounds. This type of booster seat lifts your child so your car's seat belt fits them properly, and also provides neck and head support.

No-back booster

For children weighing up to 120 pounds. A no-back booster seat lifts your child so your car's seat belt fits them properly, but doesn't provide neck or head support. This type of booster seat can be used in vehicles that have head restraints or headrests.

Car booster seat use tips

  • Always use booster seats with the shoulder and lap belt.
  • Center the shoulder belt across your child’s shoulder and chest.
  • Place the lap belt low on the hips; it should touch your child’s upper thighs.
  • No-back boosters must be used with a vehicle head restraint or headrest to protect your child’s head.
  • Properly adjust the head restraint or headrest.

Make sure your toddler stays buckled in their car seat

While you can take all the necessary steps to ensure your car seat is installed correctly, some toddlers may find a way to unbuckle the harness themselves. To help prevent this, talk to your child about why it's not safe to unbuckle their car seat and help them understand why you'll need to stop the car if they aren't buckled in. During the car ride, entertain your toddler with games, songs, or snacks to help keep their attention off of the car seat.
