When passing another vehicle, pedestrian, or bicyclist, the assumption that they may move into your traffic lane is crucial for ensuring safety on the road. This acknowledges that other road users may not always be aware of your intentions or the presence of your vehicle, especially if they are not looking in the direction of oncoming traffic or if they are focused on their own path. By expecting that they might change direction unexpectedly, you maintain a safer distance and are better prepared to react if necessary.

This assumption emphasizes the importance of vigilance and caution while driving. It encourages drivers to allow for greater space when passing, particularly with vulnerable road users like pedestrians and bicyclists, who might not have the same perception of speed or might be preoccupied with their surroundings. Being conscious of the possibility of their movement helps to reduce the risk of collisions and enhances overall road safety.
