Octagon (Stop): This eight-sidedshape always means stop. You must come to a complete stop at the sign, stop line, pedestrian crosswalk or curb. Wait for any vehicle or pedestrian to clear the way.
At some intersections you’ll find a sign beneath the stop sign that reads “All Way” or “4 Way.” At these intersections all vehicles on all roads leading into the intersection must stop. If you get to the intersection at the same time as other vehicles, the driver on the left must yield to the driver on the right.
Triangle (Yield): You must slow down as you come to the intersection. Be prepared to stop. Let any vehicles, pedestrians or bicyclists safely pass before you proceed.
Rectangle (Regulatory or Guide): Vertical signs generally give instructions or tell you the law. Horizontal signs may give directions or information.
Diamond (Warning): These signs warn you of special conditions or hazards ahead. Slow down and drive with caution. Be ready to stop.
