In which situation should you refrain from passing another vehicle?

Refraining from passing another vehicle is important for maintaining safety on the road. When a driver is using their turn signal, it indicates their intention to change lanes or make a turn, which means that passing them could lead to a collision if they proceed with their intended maneuver. Similarly, if a driver is looking at street signs, they may be preparing to make a decision about their route, which could involve changing lanes or stopping, making it unsafe to pass. Additionally, if a driver is slowing down, this could be a sign that they are preparing to stop or turn. In all these scenarios, passing may create a dangerous situation for both drivers. Thus, it is crucial to exercise caution and avoid passing whenever any of these indicators are present, highlighting the importance of observing other vehicles and their signals on the road.
