TALLAHASSEE, Fla. – Parents in Florida are currently required to keep their children in booster or car seats until they turn 5 years old. For a decade, the federal government has recommended that age 7 be the cutoff for these seats. But even a compromise that would raise the age to 6 hasn’t gone anywhere in the Florida Legislature. Raising the age limit from 5 to 6 is a move supported by science. He said the biggest challenge will be educating parents on the changes if the age limit is increased.
