What is the purpose of a pennant shaped sign?

A pennant-shaped sign serves a specific function in traffic control and safety by indicating a no-passing zone. These signs are typically placed in areas where overtaking other vehicles is prohibited due to safety concerns, often on winding roads or where visibility is limited. The shape of the sign – which resembles a flag or pennant – is intended to catch the attention of drivers and convey an important message quickly and effectively.

Because of its unique shape, drivers can easily recognize it and understand that they need to refrain from passing other vehicles to ensure their safety and the safety of others on the road. This proactive measure helps prevent accidents in hazardous areas. The other types of signs, while important, serve different purposes: stop or prohibition signs communicate restrictions; warning signs alert drivers to potential hazards; and regulatory signs provide directives that must be followed. Each type plays a critical role, but the pennant shape is exclusively associated with no-passing zones.
