Pennsylvania · Pavement Markings

Every line on the road, decoded.

Yellow vs white, solid vs broken, double lines, arrows, crosswalks, stop bars: what each marking means and what's allowed in Pennsylvania.

How pavement markings work

Pavement markings follow the federal MUTCD standard, so the same color and pattern mean the same thing in every state. Color tells direction: yellow separates traffic moving in opposite directions; white separates traffic moving the same way. Pattern tells permission: broken lines may be crossed when safe; solid lines may not. Doubling intensifies: a double-solid yellow means no passing in either direction.
