Which system is the supplemental restraint system (SRS) primarily associated with?

• A. The anti lock braking system
• B. The electronic stability control
• C. The air bag system
• D. The roof airbags only

Answer: (C)

SRS stands for Supplemental Restraint System, and its role is to provide additional protection during crashes by deploying airbags and related devices. The defining component of this system is the airbag system, which works in concert with seat belts to restrain occupants and reduce injury risk when a collision occurs. Braking and stability controls like anti-lock brakes and electronic stability control influence crash avoidance and vehicle handling, not the deployment of restraints after a crash. Roof airbags can be part of the overall SRS, but the concept of SRS is centered on airbags and their associated components. So the best answer is the air bag system.
