Question: 1 / 400

How can you maintain a safe following distance?

Use the "2-second rule" regardless of conditions

Use the "3-second rule" and adjust for conditions

Maintaining a safe following distance is crucial for preventing collisions and ensuring adequate reaction time. The "3-second rule" is widely accepted as a guideline for determining a safe distance between your vehicle and the one in front of you. This rule suggests that you should be able to count to three after the vehicle ahead of you passes a stationary object, like a sign or a tree, before you reach the same object.

This approach allows for adequate time to react in various driving conditions, such as inclement weather, heavy traffic, or unexpected obstacles. Adjusting for conditions, such as increasing your following distance in rainy, snowy, or foggy weather, is essential because these conditions can affect your vehicle's handling and stopping distance. By using the "3-second rule" and being mindful of specific circumstances, you can significantly reduce the risk of rear-end collisions and enhance overall driving safety.
