What does a pennant sign on the roadway indicate?

A pennant sign is a specific type of traffic sign that is always mounted at an angle and is used to indicate a no-passing zone. This sign is particularly important for drivers, as it warns them that they are approaching an area where overtaking another vehicle is prohibited due to unsafe conditions. The presence of a pennant sign signals to drivers to stay in their lane and not attempt to pass other vehicles, enhancing safety on the roadway.

The context of why this warning is crucial is rooted in factors like road visibility, sharp curves, or hills that may limit a driver's ability to see oncoming traffic. Recognizing the significance of such signage helps in making informed and safe driving decisions.
