A supplemental restraint system consists of:

A supplemental restraint system consists of:

• A. Seat belt
• B. Air bag
• C. Seat belt and air bag system
• D. Seat belt and rollover bar

Answer: (D)

The idea behind a supplemental restraint system is to protect occupants by adding protective elements that work with the primary restraint. The seat belt is the main restraint that keeps a person in place and reduces movement during a crash. In rollovers, a rollover bar provides structural protection to maintain a survivable space and prevent the occupant from being crushed or ejected. When you combine a seat belt with a rollover bar, you get both active restraint and structural protection that specifically address the risks of rollover events. Airbags are important safety devices that work with seat belts, but they’re not the restraint itself in this framing. The pair of seat belt and rollover bar best represents the protective system described here.
