When to switch to a booster seat

Learn booster seat requirements and tips to keep your child safe

Share:

Eventually, your once teeny tiny child will outgrow their car seat. But that doesn't mean they are ready to travel in a car like an adult with only a seat belt. A booster seat helps the seatbelt fit your child properly and keeps them safe in case of a car crash. In fact, children are 60% safer in a booster seat as opposed to a seat belt alone.

But since there is no one age that determines when a child can use a booster seat, it's not always clear when it's time to make the switch. See guidelines to make sure you don't switch too soon.

When can a child start to use a booster seat?

A child is ready for a booster seat when they have outgrown the height or weight limit of their 5-point harness car seat. This is usually when they reach over 65 pounds or 49 inches. You can check your car seat's manual for its height and weight limits and if it can be converted to a booster seat.

There is no one age that means your child is ready to switch from a car seat to a booster seat. Generally, kids are between the ages of 5-9 when they begin to outgrow the weight limitations of a 5-point harness car seat. Before you make the move to a belt-positioning booster seat, make sure your child meets these requirements:

  • Generally, kids weighing over 65 pounds are ready to switch to a booster seat.
  • When your child reaches 49 inches (about 4 feet) tall.
  • When you believe your child is mature enough to properly sit in a booster seat with the seat belt correctly positioned at all times.

It's important not to rush the switch to a booster seat. If your child still fits the height and weight requirements of their car seat, that is their safest option.

How do you install a booster seat?

A booster seat is typically held in place by the child's weight and the vehicle's lap-and-shoulder belt. Some seats do use your car's lower anchors and LATCH system like a car seat. It's important to read the booster seat instruction manual before installing your child's booster seat. Your car's instruction manual can also help you determine how to properly and safely install the seat. If your car doesn't have headrests, you should use a high-back booster seat.

Here are some important tips to follow when you install your child's booster seat:

  • Always place the booster seat in the back seat.
  • Always use a lap and shoulder seat belt with the booster seat.
  • Place the booster seat flat on the vehicle seat.
  • Have your child sit in the booster seat and pull the seat belt across your child's body to make sure the belt fits properly. The seat belt should rest low on the hips, not across the stomach. Across the chest, the belt should lie firmly in the middle of the child's shoulder.

When can a child stop using a booster seat?

Texas law requires that all children use a car seat or booster seat until they are 8 years old or 4 feet, 9 inches tall. Even if your child is 8 and it is legal for them to stop using a booster seat, if they are under 4 feet 9 inches tall, you should continue to use a booster seat to keep your child safe. When your child reaches the height requirement, the seat belt will fit them safely and comfortably.

Children should always travel in the back seat of the car, never the front, until they are 13 years old. They should always have the seat belt on their chest, never around their back. The lap belt should rest against their hips, and the shoulder belt should rest in the middle of their shoulder. If it doesn't, you should keep using the booster seat.

Do booster seats expire?

Yes, car seats and booster seats do expire. That's because of wear and tear and changing regulations along with recalls and manufacturer testing. In general, car seats expire between 6 and 10 years from the manufacture date.

Before you purchase a used booster seat or borrow one from a friend, check for a recall from the manufacturer's website. Safe Kids also maintains an ongoing list.

If you can't find an expiration date on the bottom or back of the booster seat, you can also check the manufacturer's website for your booster seat brand and information on how to find the expiration date.
