Regulatory signs tell you what the law requires: stop, yield, speed limits, turns and lanes. Most are white rectangles with black or red. Red means stop, yield or a prohibition; a red circle with a slash means “no”.

The red circle and slash over a truck mean trucks are excluded from this road. These selective exclusion signs tell specific vehicle types that a law keeps them off. Drivers of other vehicles may still use the road.
