Two-Way Traffic Markings Long Descriptions

The "Two-Lane Roadways" figure shows Passing Permitted is a two-way marking with passing permitted in both directions." A two-lane roadway is shown with a centerline marking of a broken yellow line. Arrows show that the direction of travel is one lane in each direction.

No Passing Zones and Edge Lines is a two-way marking with no-passing zones. A two-lane roadway is shown with centerline markings of (from the top to the bottom of the figure): a single broken yellow line; a solid yellow line adjacent to the left lane and a broken yellow line adjacent to the right lane; a double solid yellow line; a broken yellow line adjacent to the left lane and a solid yellow line adjacent to the right lane; and a single broken yellow line. In the middle of the figure, each section of solid yellow line, this overlaps in the section having a double solid yellow line. A solid white line is marked on the outside edge of each lane. Arrows show that the direction of travel is one lane in each direction.

A legend shows a black arrow indicating the direction of travel in the lanes.

The "Multi-Lane Roadways" figure shows a Without Left Turn Lanes is a four-lane roadway is shown. Arrows show that the direction of travel is two lanes in each direction. The roadway has a centerline marking of a solid double yellow line. A broken white line separates lanes traveling in the same direction.

Channelized Left Turn Lanes is a five-lane roadway is shown with the fifth, center lane used for left turns. Arrows show that the direction of travel is two through lanes in each direction and left turns from the center lane. The roadway has markings of a solid double yellow line and alternating left turn channels marked with a solid white line to separate the turn lane from through traffic lanes traveling in the same direction. The turn lanes have optional white left-turn arrows marked on the pavement. A broken white line separates through lanes traveling in the same direction.

Two-Way Left Turn Lane in Center is vertical five-lane roadway is shown. Black arrows show that the direction of travel is southbound in two left lanes and northbound in two right lanes. A fifth lane is in the center. A solid white line is marked on the right edge of each side of the roadway. Along the entire length of the figure (except within intersections), a broken white line separates the two southbound through lanes and a broken white line separates the two northbound through lanes.

At the top of the figure, the innermost southbound through lane is separated from the center lane by a solid yellow line. A broken yellow line is east of it just inside the center lane. Another broken yellow line is on the east side of the center lane adjacent to a solid yellow line separating it from the innermost northbound through lane.

A horizontal street is shown intersecting the vertical roadway. South of this intersection, the markings separating each of the lanes are shown continuing in the same pattern as north of the intersection. In the center lane, a white left-turn arrow is shown curving to the south and east. Just beyond it, another white left-turn arrow is shown curving to the north and west.

Just south of these arrows, the broken yellow lines in the center lane are not shown. After a short distance, a second solid yellow line is shown adjacent to the solid yellow line separating the center lane and the innermost northbound through lane. Beyond this point, a solid white line is shown separating the center and the innermost southbound through lane, and a white left-turn arrow is shown in the center lane, curving to the south and east.

Just below the left-turn arrow, an intersection is shown of the vertical roadway with a horizontal street. South of this intersection, another white left-turn arrow is shown in the center lane, curving to the north and west. South of the intersection, a solid double yellow line separates the center and the innermost southbound through lane, and a solid single white line separates the center and the innermost northbound lane.

A legend shows a black arrow indicating the direction of travel in the lanes.

The "Three-Lane Roadways" figure shows Passing Permitted in Direction Having Single Lane is a two-way marking with passing permitted in single-lane direction. A three-lane roadway is shown with arrows indicating the direction of travel as a single lane traveling south and two lanes traveling north. A broken yellow line is shown adjacent to the southbound lane, and a solid yellow line is shown adjacent to the leftmost of the two northbound lanes. A broken white line is shown separating the two northbound lanes. A solid white line is shown on the outer edge of the southbound lane and the rightmost northbound lane.

Passing Prohibited in Direction Having Single Lane is a two-way marking with passing prohibited in single-lane direction." A three-lane roadway is shown with arrows indicating the direction of travel as a single lane traveling south and two lanes traveling north. A solid double yellow line is shown separating the southbound lane from the leftmost northbound lane. A broken white line is shown separating the two northbound lanes. A solid white line is shown on the outer edge of the southbound lane and the rightmost northbound lane.

Travel Direction Changing in Center Lane is a vertical three-lane roadway is shown. A solid double yellow line is shown separating each lane from the others. Two southbound lanes are shown transitioning to one lane. A solid double yellow line is shown separating each lane from the others. A solid double yellow line is shown adjacent to the southbound lane. From the bottom of the figure, two northbound lanes are shown transiting to one lane. A solid yellow line is shown adjacent to the northbound lane in this taper. The taper is shown the Buffer Zone in the end of the southbound and northbound lane.

Reversible Center Lane is a vertical three-lane, two-way roadway is shown. Arrows show that the direction of travel in the left lane is southbound, the right lane is northbound, and the center lane can be either. Broken double yellow lines are shown separating the lanes from each other. A legend shows a black arrow indicating the direction of travel in the lanes.
