Why is it important to allow extra space when following another vehicle?

Allowing extra space when following another vehicle is crucial for having sufficient time to react in case the vehicle in front of you makes a sudden stop. This extra space serves as a buffer zone that can accommodate unexpected changes in traffic conditions. If the vehicle ahead brakes abruptly or encounters an obstacle, having that additional space gives you the necessary distance to slow down or stop without risking a collision.

In scenarios where the road conditions change—due to traffic, weather, or mechanical issues—this buffer becomes even more vital. It enhances safety for both the driver and passengers within the vehicle you are following, as well as for other road users. Maintaining a proper following distance is a fundamental aspect of defensive driving and is essential for preventing accidents.
