The__________becomes critical if you are in a situation where you may be struck from the rear.

The concept of following distance is especially important in the event that you might be struck from behind. Maintaining an adequate following distance allows you to have a buffer zone between your vehicle and the one in front of you. This is essential because if you are rear-ended, having space can enable you to react more effectively, such as moving forward and away from the impact or gaining control of your vehicle.

A proper following distance gives you more time to respond to sudden changes in traffic or emergencies, allowing you to brake safely without being too close to the vehicle ahead. This not only enhances your safety but also minimizes the risk of being pushed into a more dangerous situation, such as colliding with another vehicle or obstacle if you are struck from behind.

Thus, in situations where the risk of a rear-end collision is heightened, maintaining a safe following distance is vital for both your safety and the safety of other road users.
