A seat belt is also called a safety belt. Seat belts protect people from needless death and injury. A seat belt reduces the likelihood and severity of damage in a traffic collision by stopping the vehicle occupant from hitting hard against interior elements of the vehicle. If you are driving a forklift, buckle up! Forklifts come equipped with seat belts. Forklift safety belts are designed to prevent drivers from jumping out of the truck if it tips over.
