Seat belts primarily function to

• A. Provide no safety benefit
• B. Help you turn faster
• C. Counteract the effects of inertia by keeping you in your seat
• D. Increase the risk of injury

Answer: (C)

Inertia and restraint systems: when the car suddenly decelerates, your body wants to keep moving forward. A seat belt supplies the restraining force that holds you in place, turning that forward motion into a controlled stop. By keeping you seated, the belt spreads the stopping forces across stronger parts of your body, like the pelvis and torso, which reduces the risk of contacting the interior or being ejected. It also helps position you so airbags can cushion you effectively. That’s why the best choice is that seat belts counteract the effects of inertia by keeping you in your seat. They don’t help you turn faster, they do provide a safety benefit, and they don’t increase injury risk—in fact, they reduce it when worn correctly.
