Seat belts are designed for older children and adults. Most children are at least 4’9” (145 cm) tall before they can safely use the adult seat belt.
When buckled with a lap/shoulder belt, your child is ready for a seat belt only when all the following are met:
• Your child's back is against the back of the vehicle seat (no slouching); and
• Your child's knees bend comfortably over the edge of the vehicle seat; and
• The shoulder belt fits touching across the chest and crossing between the child’s neck and shoulder (NOT on the neck or face); and
• The lap belt fits snugly across your child's hip bones, touching the thighs (NOT on the stomach); and
• The child can sit in this position the entire ride.
If your child does not meet all the above, it is recommended that you continue to use a booster seat.
Tips:
• A child may pass all 5 steps to use a seat belt in one car, but still need to use a booster seat in another vehicle.
• Make sure your child has support behind the head to the tops of their ears.
• Never put two children in the same seat belt.
• Never place the shoulder strap behind your child's back or tucked under the arm.
• Your child is safest in the back seat until they are 13 years old. Most vehicles have front seat air bags, and these can hurt your child if the bags inflate during a crash or sudden stop.
