What might you have to do at an intersection indicated by warning sign M1?

At an intersection indicated by warning sign M1, which typically signifies a caution regarding an upcoming intersection, it is essential to be prepared to stop or yield. This sign serves as a reminder to look out for other road users, such as vehicles, pedestrians, or cyclists, who may not have a clear right of way.

When approaching such an intersection, safe driving practices dictate that one should reduce speed, assess the situation, and be ready to either stop completely or yield to oncoming traffic or pedestrians crossing. This vigilant approach ensures that drivers can react appropriately and safely navigate the intersection, minimizing the risk of accidents.

In contrast, rapidly crossing without caution, engaging in a turn, or ignoring the need to stop or yield would compromise safety and could lead to dangerous situations for all road users. Thus, being prepared to stop or yield is the most responsible action when encountering the warning sign.
