When you see solid double yellow lines painted on the road, you may not pass. These lines represent a barrier between you and oncoming traffic. Do not drive on or over this barrier.
A single solid yellow line marks the center of a road with two-way traffic. You should not cross over this line into oncoming traffic.
The shape of a diamond is reserved exclusively for warning drivers of existing or possible hazards on roadways and adjacent areas. Diamond-shaped signs are either warning signs or work zone traffic signs.
Solid lines along the side of the road tell you where its edge is. These lines show you where the travel lane ends and the shoulder begins. It is illegal to drive across the edge line, except when told to by a police officer or other authorized official or when allowed by an official sign. An edge line that angles toward the center of the road shows that the road is narrower ahead. Lines that separate lanes of traffic that moves in the same direction are white.
CENTER TURN LANE. The center lane is shared for left turns in both directions of travel. Traveling or passing in the center turn lane is forbidden.
