Question 3982
If nothing prevents it from working effectively, which passive safety system keeps the submarine effect from occurring in the event of an accident?
- The airbag.
- The head restraint.
- The seat belt.
Show answer and explanation
Correct answer: The seat belt.
A snug seat belt holds your hips in place with the lap belt and prevents your body from sliding underneath it in a crash. That sliding is called submarining. A cushion, a towel, or a loose belt prevents it from working properly. The head restraint protects your neck, and the airbag cushions the impact against the steering wheel.
