Airbags deploy when the vehicle experiences an impact exceeding which speed into a fixed object?

• A. Over 10 MPH
• B. Over 20 MPH
• C. Over 5 MPH
• D. Over 15 MPH

Answer: (A)

Airbags deploy when the car decelerates rapidly in a crash. The system uses sensors to detect this quick slowdown and inflates the bags once a certain deceleration threshold is reached. For a crash into a fixed object, that threshold corresponds roughly to an impact speed of about ten miles per hour. At that speed, the rapid deceleration is enough to justify inflation to cushion occupants before they strike the interior surfaces, reducing injuries. Impacts slower than that are unlikely to trigger deployment to avoid unnecessary inflation from minor bumps.
