Final answer:
Always use a safety belt to protect yourself against possible collisions caused by other drivers, and take advantage of other safety features like airbags and car crumple zones.
Step-by-step explanation:
To defend yourself against possible collisions due to other drivers, you should always use a safety belt. Wearing a safety belt is a crucial safety measure in automobiles, as it secures the passenger or driver to their seat. This is to prevent them from being thrown from their seat in the event of a sudden stop or impact. Additionally, essential safety features include airbags, which work in concert with safety belts by providing a cushion to reduce the impact force on the occupants. Cars are also designed with crumple zones that help to increase the duration of the impact, thus lessening the force exerted on passengers. Avoiding unnecessary risks, like dangerous stunts, and maintaining a safe and aware driving practice also contribute to collision prevention.
