When stopping behind a stationary vehicle, what is the recommended gap you should aim for?

When stopping behind a stationary vehicle, the recommendation to view the rear tyres and some road surface is based on ensuring safety and awareness of your surroundings. This guidance allows the driver to maintain a safe stopping distance while also providing a clear view of the area behind the vehicle ahead.

By being able to see the rear tyres and a portion of the road surface, the driver can gauge the space between their vehicle and the one in front. This visibility is crucial as it enables quick reactions if the vehicle in front begins to move or if there are any changes in the traffic situation. It also helps prevent potential collisions by ensuring that there is enough space to maneuver if necessary.

In contrast, aiming for a specific distance like 1 meter or a foot distance may not provide the situational awareness that is crucial in dynamic traffic conditions. Leaving no gap may indeed prevent disruptions, but it compromises the ability to react should the vehicle ahead move unexpectedly or if there's a need to maneuver safely. Therefore, the correct recommendation reflects a balance of safe stopping distance and situational awareness.
