Road sign FAQ
What does a yellow diamond sign mean?
A yellow diamond-shaped sign is a warning sign. It alerts you to a hazard or a change in the road ahead — such as a curve, intersection, or crossing — so you can slow down and be ready to react.
What shape and color is a stop sign?
A stop sign is a red octagon (eight-sided) with white letters. The octagon shape is used only for stop signs, so you can recognize it even from behind or in poor visibility.
What does a fluorescent yellow-green sign mean?
Fluorescent yellow-green signs mark pedestrian, bicycle, and school crossings. The bright color draws extra attention to areas where people may be crossing the road.
What do orange road signs mean?
Orange signs indicate a construction or work zone. They warn of temporary conditions like road work, lane closures, flaggers, or detours, and usually mean you should slow down and stay alert.
What does a pennant-shaped sign mean?
A horizontal, sideways-triangle (pennant) sign on the left side of the road marks the start of a no-passing zone. It tells drivers it is unsafe and illegal to pass other vehicles.
