The 5 Step Test
If you answer "No" to any of these questions, your child must be in a booster seat:
1. Does the child sit all the way back against the auto seat?
2. Do the child's knees bend comfortably at the edge of the auto seat?
3. Is the lap belt touching the top of the thighs, not the tummy?
4. Is the shoulder belt centered on the shoulder and chest?
5. Can the child stay seated like this for the whole trip?
BELT-POSITIONING BOOSTER:
- Used to raise child up and correctly position the car's seatbelt on the child's body.
- CAN NOT be used with only a lap belt!
(See your car dealer for a lap/shoulder belt retrofit.)
