CDC COMMUNITY GUIDE: Use of Safety Belts: Laws Mandating Use

CDC

An Evidence-Based Practice

Description

Safety belt laws mandate the use of safety belts by motor vehicle occupants. All current U.S. laws cover front seat occupants. Other requirements, such as rear seat coverage, fines, affected age groups, type of enforcement, and exempted vehicles and drivers vary by state.

The Community Preventive Services Task Force recommends safety belt laws as a strategy based on strong evidence of their effectiveness in increasing safety belt use and reducing fatal and non-fatal injuries among adolescents and adults.
