In the United States, motor vehicle crashes are a leading cause of death among children. In 2018, 636 children 12 years old and younger died in motor vehicle traffic crashes, and more than 97,000 were injured. Of the children 12 years old and younger who died in a crash in 2018 (for which restraint use was known), 33% were not buckled up. Parents and caregivers can make a lifesaving difference.
