Safety guidance

Even when Indiana law allows a seat belt, NHTSA, CDC, and AAP guidance may still recommend a booster until the vehicle belt fits properly.

Understand age, height, weight, and seat belt fit.

See when children typically start and stop using boosters.

Know when to move from harnessed seat to booster.
