Two adjacent travel lanes are separated by a broken white line. What does the color indicate?
Correct answer: Both lanes carry traffic in the same direction.
White lane lines separate same-direction traffic. A broken line permits a careful lane change, not an automatic right of way.

Your side of a yellow center-line pair is broken. What does that allow?
Correct answer: Passing when safe and otherwise permitted.
The broken side allows a safe passing maneuver. Visibility, oncoming traffic and other restrictions still matter.

The yellow line beside your lane is solid; the other is broken. May you cross to pass?
Correct answer: No; the solid side prohibits passing.
The restriction follows the line nearest your lane, not the pattern on the opposite side.

Two solid yellow center lines separate opposing lanes. Which passing restriction applies?
Correct answer: Neither direction may cross them to pass.
Both directions are in a no-passing zone. This question concerns overtaking, not every possible turning situation.

Double solid white lines separate your lane from an adjacent lane. What do they mean for a lane change across them?
Correct answer: Crossing the lines is prohibited.
A double solid lane line marks a crossing prohibition. Do not treat it like a normal broken white line.

A wide dotted white line separates your lane from a continuing lane, and your lane is marked EXIT ONLY. What should you expect?
Correct answer: Your lane leaves the through roadway at the exit.
Lane-drop markings distinguish a continuing lane from one that ends in a required turn or exit. Read the lane-use signs early and plan a safe move if you need the continuing lane.

Dotted guide lines extend through an intersection with two turning lanes. How should you use them?
Correct answer: Follow your turning lane through the intersection.
Dotted extensions help drivers follow lane alignment through a turn or transition. They do not invite drivers in adjacent turning lanes to crowd into the same path.
