Two lanes are separated by a yellow center line. What does the color tell you about their traffic?
Correct answer: The lanes carry traffic in opposite directions.
Yellow center lines separate opposing traffic. The pattern of the lines and the road situation determine whether passing is permitted.

A white lane line separates two adjacent travel lanes. What does that color normally indicate?
Correct answer: The lanes carry traffic in the same direction.
White lane lines separate same-direction lanes. Their color has a different meaning from yellow center lines separating opposing flows.

A two-way road has the single broken yellow center line shown. What does the marking permit?
Correct answer: Passing from either direction when the maneuver is otherwise safe and lawful.
A broken yellow center line identifies a passing-permitted section in both directions. It does not remove the need for a clear view, a safe gap, and compliance with other restrictions.

You are in the lane beside the solid yellow line in this pair. What does that mean for passing a slower car?
Correct answer: You must not cross the center lines for that pass.
The center-line pattern applies according to the line nearest your lane. A solid yellow line on your side prohibits passing across it.

You are beside the broken yellow line, with a solid yellow line beyond it. How does the marking affect a proposed pass?
Correct answer: Passing may be allowed from your side if traffic, visibility, and other rules permit.
A broken line on your side permits a pass when safe and otherwise lawful. Drivers on the solid-line side do not have the same passing permission.

What do the two solid yellow center lines tell drivers who want to pass an ordinary car?
Correct answer: Passing across the lines is prohibited in both directions.
Double solid yellow lines establish a no-passing section for both traffic directions. This item concerns overtaking a car, not a separate left-turn maneuver.

You need to turn left into a driveway across solid yellow center lines, with no sign prohibiting the turn. What does Alaska's handbook say?
Correct answer: The lines do not prohibit this driveway turn, but you must wait until it is safe.
Alaska distinguishes a left turn into a driveway from passing across solid yellow center lines. The turn still requires a safe gap and yielding to conflicting traffic.

What does the broken white line between the two same-direction lanes indicate?
Correct answer: A lane change is permitted when it can be made safely.
A broken white line allows lane changes but does not give the changing driver priority. Check traffic and signal before crossing it.

What does the single solid white line between these same-direction lanes communicate?
Correct answer: Changing lanes across it is discouraged.
A solid white lane line discourages lane changes. It is different from both a broken white lane line and a yellow center line.

In the diagram, what does the solid white line along the far-right edge identify?
Correct answer: The edge of the roadway or shoulder boundary.
An edge line outlines the roadway; the area beyond it is not automatically a travel lane. Alaska's handbook warns against treating the shoulder as a driving lane.

On a divided or one-way roadway, what does the solid yellow line at the left edge identify?
Correct answer: The left boundary of that roadway.
The yellow line marks the left edge on divided or one-way roadways. Its position matters: this edge line is not a second travel lane or a median entrance.

What is the purpose of the center lane marked with opposing left-turn arrows and solid/broken yellow boundaries?
Correct answer: Left turns by traffic from either direction.
The shared center lane is reserved for left-turning vehicles. Alaska's handbook says it must not be used for driving through, accelerating, or passing.
