Signs & Signals
Maine traffic signs use shape and color to tell you what to do before you can read the words. Signals and pavement markings work with them, and rural roads add wildlife warnings you should heed.
Shapes and colors
A red octagon means STOP and a triangle means YIELD. Yellow diamonds warn of hazards, including deer and moose crossings common in Maine. Red prohibits, orange marks work zones, green guides, and blue lists services.
Pavement markings
Yellow lines separate opposing traffic; a double solid yellow line means no passing in either direction. White lines separate lanes going the same way, with broken lines allowing lane changes when safe.
Traffic signals
Steady red means stop and stay stopped; steady yellow warns of a coming red; steady green means go when clear. Flashing red is a STOP sign, and flashing yellow means slow down and proceed with caution.
