If another vehicle is passing you, what is a recommended action to ensure safety?

When another vehicle is passing you, the recommended action of slowing down a bit helps to facilitate a safer and smoother passing maneuver. By reducing your speed slightly, you create additional space between your vehicle and the one that is overtaking you. This extra space allows the passing vehicle to maneuver more easily and reduces the chances of a collision, especially in situations where there may not be sufficient distance for overtaking safely.

Maintaining the same speed, as suggested by one of the other choices, can create a potential hazard while another vehicle is trying to pass, as it may lead to the overtaking vehicle attempting to enter your lane before they have fully cleared your vehicle. Speeding up to allow the passing vehicle to get ahead more quickly might also create an unpredictable situation, as it can lead to misjudgments regarding distances and the speed of approaching traffic. Changing lanes immediately without ensuring it is safe may result in an unexpected maneuver that could compromise safety for both vehicles.

Thus, slowing down a bit is the safest recommended action in this scenario, promoting a more cautious approach to driving when sharing the road with others.
