Permit Test - Lines

YELLOW LINES mark the center of a two-way road used for two-way traffic.

WHITE LINES painted on the pavement indicate traffic traveling in your direction

Broken White Line: you may change lanes if it is safe to do so. A white line separates lanes of traffic moving in the same direction. The dashed lines indicate that you are free to change lanes and stay in that other lane.

Solid White Line: requires you to stay within the lane and also marks the shoulder of the roadway. Solid white lines also separate two lanes going the same direction. However, if the line is solid, this indicates that you should not change lanes. These are often used in construction areas to discourage drivers from moving around too much, on highway exits to distinguish a separating lane, and to distinguish carpool lanes from the regular flow of traffic.

Double solid yellow lines in center Yellow lines separate two lanes of traffic moving in opposite directions. If there are two solid yellow lines, this means you are not allowed to pass the car in front of you by crossing into oncoming traffic. A double yellow line indicates that passing is not allowed from either side of the road.

if the yellow line is dashed, this means that you are free to pass a slow or stopped car by crossing onto the other side of the road if the coast is clear. A single dashed yellow line indicates that passing is allowed from either direction. Treat the opposing lane as a temporary additional lane, using your turn signal to indicate your intent.

if both the dashed and solid yellow lines are present, passing is only allowed by one direction of traffic. If the line on your side of the road is solid, you should not pass, even if the other side is dashed. Only the dashed side of the road can pass.

these solid white lines running along the edge of the road indicate the "shoulder" of the road and let you know that — if the line is on your right side — you're headed in the same direction as traffic. Both sides will be white if a yellow line is present in the center of the road.

It's a rare sight in the USA, but if you come across zigzag white lines here or abroad, this means you should not park your car on that area of the road. If you part your car on a berm with zigzag road lines, you will get ticketed or towed.
