What is the primary reason safety belts are important to a driver?

• A. To protect the driver from inertia
• B. To prevent the vehicle from rolling
• C. To improve acceleration
• D. To reduce noise

Answer: (A)

The main idea is that safety belts counter inertia. When the car stops suddenly or crashes, your body tends to keep moving forward at the car’s speed. A seat belt holds you in your seat, so your body slows with the car instead of flying forward, reducing injury by keeping you from hitting the steering wheel or being ejected. It also helps position you correctly for airbags to provide their protection. The belt doesn’t affect whether the vehicle rolls, nor does it change acceleration or reduce engine noise.
