In defensive driving, what is the recommended following distance?

Maintaining a safe following distance is crucial for defensive driving because it provides adequate time and space to react to any sudden changes in traffic conditions. This distance allows drivers to see the road ahead clearly and respond to unexpected stops, obstacles, or emergencies that may arise.

The idea is that a safe following distance can prevent collisions, especially in situations where the vehicle in front of you must stop suddenly. By keeping this space, you give yourself a cushion to brake safely or avoid potential hazards. It's typically recommended that drivers use the "three-second rule," which involves measuring the time it takes for the vehicle ahead to pass a fixed point on the road and ensuring that you maintain that distance with a minimum of three seconds.

Other choices suggest either being too close to other vehicles or maintaining a distance that may not provide enough reaction time. Options such as staying right up next to the vehicle ahead could lead to dangerous situations if the front vehicle had to stop suddenly. Therefore, the focus on maintaining a safe distance to react effectively in various road conditions underlines the importance of defensive driving principles.
