Final answer:
In the event of an imminent rear-end collision, the best course of action is to keep your hands on the steering wheel and make sure you're properly restrained. Opening the car door, bracing against the dashboard, or jumping out of the car are not safe actions and could result in more severe injuries.
Step-by-step explanation:
If you can't avoid a collision and are about to be hit from the rear, you should keep your hands on the steering wheel. This is important because it helps you maintain control of your vehicle as much as possible during and after the impact. Additionally, making sure you are properly restrained by your seat belt and your headrest is adjusted to the correct height can also help minimize injury. It's crucial not to panic; bracing for impact by stiffening up can lead to more severe injuries. Instead, maintaining a normal posture, being relaxed, and trusting the safety features of your car, such as the headrest and seatbelt, is advisable. Do not attempt to quickly open the car door or jump out of the car, as these actions can lead to greater harm. The force of the collision can make these actions unpredictable and dangerous, potentially putting you at risk of being hit by your own or another vehicle. It is also not recommended to brace yourself against the dashboard, as this can cause injury to your hands, face, or head due to the force of the impact.
