An official website of the United States government.
Here's how you know
The .gov means it's official.
Federal government websites always use a .gov or .mil domain. Before sharing sensitive information online, make sure you’re on a .gov or .mil site by inspecting your browser's address (or "location") bar.
This site is also protected by an SSL (Secure Sockets Layer) certificate that's been signed by the U.S. government. The https:// means all transmitted data is encrypted — in other words, any information or browsing history that you provide is transmitted securely.
Occupant protection discussed in this fact sheet includes seat belts, car seats for those under 5, and frontal air bags in passenger vehicles. Passenger vehicles consist of passenger cars and light trucks (pickups, SUVs, and vans) with gross vehicle weight ratings (GVWRs) of 10,000 pounds or less. Vehicle occupants include drivers and passengers.
