Which statement about supplemental restraint systems (SRS) is false?

The correct answer indicates that it is false to say that supplemental restraint systems (SRS) cannot deploy if the car is not running. In fact, SRS can deploy even when the vehicle's engine is off. The deployment system operates using sensors that detect a collision, and these sensors do not rely on the car being in operation to trigger the airbag or other restraint systems. This is crucial for safety because a passenger may not always have the vehicle running at the moment of an accident, yet the restraint systems need to function effectively to protect occupants at all times.

The other statements are true: SRS can indeed deploy regardless of vehicle speed, as the deployment is based on the severity of the impact detected rather than how fast the vehicle is traveling. Also, SRS is designed to work in conjunction with seatbelts to enhance occupant protection by reducing the risk of contact with the steering wheel, dashboard, or windshield. Lastly, the statement about SRS deployment being hazardous is also accurate, as deploying airbags can cause injuries due to the high-speed inflation and can potentially lead to complications if the deployment occurs in situations where a passenger is too close to the airbag.
