What does warning sign M1 alert you to?

The warning sign M1 indicates that there is a potential hazard ahead where roads may cross, signaling drivers that they need to be prepared to stop. This is crucial for safety, as intersections can be high-risk areas due to the presence of other vehicles, pedestrians, and cyclists. Being aware of this warning allows drivers to reduce speed and be on the lookout for any oncoming traffic or obstacles, ensuring they can navigate the crossing safely.

While potholes, speed limits, and road work are all important concerns for drivers, they are indicated by different specific signs. The M1 specifically focuses on alerting drivers to the possibility of road intersections, which requires immediate attention and caution.
