How long does my child need to stay in a safety seat?
According to Marylands law, every child under 8 years old must ride in a booster seat or other appropriate child safety seat (including infant seats, convertible seats, forward-facing seats, booster seats, or other federally approved safety devices) unless the child is 4 feet 9 inches or taller or weighs more than 65 pounds. However, nationally recognized best practice* recommendations are for most children to ride in booster seats until they are big enough for lap/shoulder belts to fit properly.
