Which of the following is a requirement for safe driving?

Wearing a seat belt is a fundamental requirement for safe driving. Seat belts play a crucial role in protecting drivers and passengers during a crash by reducing the risk of ejection from the vehicle and minimizing injury severity. They help keep occupants securely in their seats and positioned properly to benefit from the vehicle's safety features, such as airbags. The importance of wearing seat belts is backed by numerous studies showing that they significantly lower the chances of fatalities and serious injuries in car accidents.

The other options present behaviors that could compromise safety. Using a cellphone while driving distracts the driver, increasing the likelihood of accidents. Driving with the windows down can cause distractions or impair hearing, especially in adverse weather conditions. Allowing other drivers to dictate your speed may lead to unsafe driving practices, such as speeding or erratic driving, if you prioritize others’ behavior over safe practices. Therefore, wearing a seat belt stands out as a clear requirement for enhancing safety on the road.
