Effective June 30, 2008, the state of Maryland, put into effect a New Child Booster Seat Law, which requires all children in Maryland to ride in an approved child booster seat until the age of 8, reach a height of 4'9", or weigh over 65 pounds. This new law also requires that children between the ages of 8-16 be secured in seat belts. Also no child under the age of 16 is allowed to ride in the back of pickup trucks.
Booster seats are intended to provide a platform that lifts the child up off the vehicle seat in order to improve the fit of the child in the adult safety belt.
According to the Centers for Disease Control, motor vehicle injuries are the leading cause of death among children in the U.S. The use of child booster seats for children ages 4-7 reduces the risk of injury from a car accident by 59% compared to using a seat belt without a booster seat.
Each year, an average of 500 children ages 4-7 die and thousands more are injured as a result of automobile accidents. According to the Partners for Child Passenger Safety, booster seats can substantially reduce the risk of death and injury to children through the age of 7. The National Highway Transportation Safety Agency's National Survey of the Use of Booster Seats states that only 25 % of children were properly secured in a booster seat.

Here are some helpful ways to determine when a child is ready to move from a child booster seat to a regular seat, according to the Safety Belt Safe and Safe USA.:
- the child, seating flush against the back of the seat, can bend his/her knees over the seat edge comfortably;
- the should belt rests between the neck and shoulder when seated;
- the lap belt is across his/her lap, not riding up on the abdomen or down on his/her thighs, when seated;
- the child is mature enough to remain in the correct position for the duration of the ride.
The fine for violating the law is $25 in the state of Maryland. 17 states, including Maryland and the District of Columbia have implemented the new booster seat law.
