Final answer:
The Florida Child Restraint Law applies to children ages 8 and under. Children 0 to 2.5 must use rear-facing car seats, while those aged 2.5 to 6 require forward-facing car seats or boosters.
Step-by-step explanation:
The Child Restraint Law in Florida applies to children ages 0 to 5 years old. Specifically, children ages 0 to 2.5 must be in a rear-facing car seat; those ages 2.5 to 6 must use a forward-facing car seat or a booster seat depending on their weight and height. It is not until they reach the age of 6 that they can potentially move on to using seat belts alone, following the proper guidelines to ensure safety. This information is critical for ensuring the safety of children in vehicles and adhering to the law. While the options provided (a) 12 and under, (b) 8 and under, (c) 6 and under, and (d) 4 and under are close, the law encompasses age group 'b', meaning that the correct answer to the question is 'b' 8 and under.
