seatbelt

/ˈsitˌbɛlt/

Other forms: seatbelts

The straps that keep you safe whether you're riding in a car or on a terrifying roller coaster are seatbelts. Buckle your seatbelt — the captain says the plane is heading for some turbulence!

In every state except New Hampshire, all drivers must wear a seatbelt (and it's a good idea to keep yours securely fastened, even when you're driving through New Hampshire). You'll buckle your seatbelt when you get seated on an airplane or in an amusement park bumper car; it's there to keep you safe. The seatbelt was invented in the 19th century and first used on a lightweight glider plane. It wasn't until 1968 that all new cars came with seatbelts.
