A seat belt (or safety belt) is a safety device used in vehicles to secure the occupant against harmful movement during a collision or sudden stop. It restrains the body, preventing ejection or impact with the interior of the vehicle. It is typically a strap that fastens across the chest and lap. Unlike airbags, it is always active. Seat belts are crucial for reducing injury and death in accidents. It's like a hug from the car, but for safety.
