Booster Seats

Stage 3: Booster Seats until the Seat Belt Fits (approx. 4’9″)

Use car seats with harnesses to the top weight or height limits for the harnesses. Once children outgrow harnesses, use a booster seat in the back seat until the seat belt fits properly. A booster seat is often needed until a child is around 4 feet 9 inches tall. Your child may be about 12 years old before he/she is ready for a seat belt.

Does your child pass the Safety Belt Fit Test?

 

Perform this test with the child sitting directly on the vehicle seat without the booster seat. If you answer “no” to any of these questions, your child is NOT ready to come out of the booster seat.

Booster Seat Safety Tips

  • Once children outgrow weight and height limits for traditional safety seats, they should travel in belt-positioning booster seats in the back seat until the vehicle seat belt fits properly, typically when they have reached 4’9″ tall and are between 8 and 12 years of age.

  • Using a booster seat with a lap/shoulder belt instead of just a safety belt reduces injury by 45% for 4 to 8-year-olds.

  • Many states (including Virginia) require by law that children travel in a child seat or booster seat until at least age 8. Graduation out of a booster seat in best determined by proper fit of a safety belt, and many small-frame youngsters will require a booster seat long past the minimum age.

  • Booster seats raise children higher, so the safety belt fits over strong, bony parts of the body (e.g., hips and chest). Seat belts fit poorly on children’s bodies, increasing injury to soft and vulnerable parts of the body (e.g., stomach and neck). Booster seats keep children safe until they are big enough to safely use regular seat belts.

Booster seat weight and height ranges

vary greatly. Read labels to determine the correct seat for age, weight, and height.

Both high-back and no-back boosters

are available. High-back boosters are useful in vehicles that do not have head restraints or have low seat backs. Backless boosters are usually less expensive and are easier to move from vehicle to vehicle. Backless boosters can be safely used in vehicles with head restraints and high seat backs.

Many high-back boosters

are actually combination seats. They come with harnesses that can be used for smaller children and can then be removed for older children.

READ the instruction manual

AND the safety belt/seat section in your vehicle manual.

Children should always

ride in the back seat until age 13.

Lap and shoulder belts

are required with booster seats. If you have only lap belts in your car, there are some alternatives, including having shoulder belts installed in your vehicle, using a safety seat with a harness system that goes up to high weights (e.g., 85 lbs.), or using a travel vest (see a list of some available vests).

Safety Restraint Misuses

The primary cause of injuries from misuse of booster seats is the misrouting of the safety belt. Common misuses of booster seats and safety belts include:

  • Shoulder belts being placed behind the child’s back, under the child’s arm, or over the booster seat arm rest
  • Shoulder belts not being placed at mid-shoulder position
  • Shoulder belts being positioned too loosely
