Ask a Trooper

Can you explain what the lines on the highways and streets indicate? I feel like a lot of people can’t figure it out. Thanks.

  Answer: I sure can. Pavement markings direct and regulate traffic.

  White lines separate lanes of traffic traveling in the same direction.

• White dashes: You can change lanes where this marking is present.

• Shorter and thicker white dashes: The lane is ending.

• Solid white line: You should not change lanes. Solid white lines also mark crosswalks, stop lines at intersections, parking stalls and the edges of a roadway.

• Double solid white lines: You must not change lanes.

• Solid white line with bicycle insignia: This area is for bicycle or electric-assist bicycle traffic only.

• If you are on a bicycle, you must travel in the same direction as adjacent traffic.

  Yellow lines separate traffic moving in opposite directions.

• Solid yellow line: You must not pass. Passing in a no-passing zone is illegal.

• Yellow dashes: You may pass.

• Mixed lines (solid and dashes): A solid yellow line may appear on one side of the roadway while a line of dashes appears on the other side. You must obey the marking in your lane of traffic.

• Double solid yellow lines: You must not pass, regardless of which side of the line you are driving.
