A booster seat is recommended for children who have outgrown child safety seats. Children who fit that description should be properly restrained in booster seats in the back seat until they are at least 8 years old or more than 4 feet 9 inches tall. A booster seat positions a child up so a safety belt can fit correctly. Without a booster seat, a small child can be ejected from a vehicle in a crash. More
