Booster Seat Law Cuts Childhood Injuries, Study Confirms

A New York state law mandating booster seats has led to a substantial reduction in injuries to children in traffic accidents, a new study in the journal Pediatrics has found.

Many studies have pointed to the benefits of booster seats, but the new report was the first to conclusively link booster seat laws to a lower rate of injury and death by comparing crash statistics before and after the New York law went into effect in 2005. The number of injuries for children ages 4 to 6 declined by 18 percent, the study found.

Booster seats may be even more effective than the study suggests, the researchers said. They cited a federal estimate that booster seats are used improperly nearly half the time — either because the child is not strapped in properly or the booster is not secured to the seat. According to the National Highway Traffic Safety Administration, booster seats saved the lives of 219 children under the age of 5 in 2008.

Children need booster seats when they have outgrown their car seats but are still too small to be properly protected by seat belts. As of March 2010, 47 states and the District of Columbia have laws requiring appropriate child restraints, but the laws vary according to age, height and weight (click here to see a state-by-state breakdown, courtesy of the Insurance Institute for Highway Safety).
