Which is a common misconception about child car seat laws?

Booster seats are designed specifically for older children who have outgrown their forward-facing car seats but are not yet tall enough to use the regular seat belts safely. Infants, on the other hand, require a car seat that provides the proper support and protection for their size and developmental stage, which is a rear-facing car seat. Many parents may mistakenly believe that booster seats can be used for infants, but this is not safe or compliant with child safety laws. Infants should always be placed in appropriate rear-facing car seats until they reach the specific weight and height requirements set by safety regulations.

The other statements reflect correct information about child car seat laws, clarifying the requirements for children at different ages and sizes. Understanding the correct use of car seats is crucial for ensuring the safety of young passengers.
