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 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 Delaware's manual say?
Correct answer: The lines do not prohibit this driveway turn, but you must wait until it is safe.
Delaware 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?

What does the single solid white line between these same-direction lanes communicate?

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.
The solid white edge line shows the outside edge of the travel lane. It is not a center line or another ordinary through-lane boundary.

What is the main 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.
Delaware reserves this shared center lane for left turns, or U-turns where they are permitted, by traffic from either direction. It is not an ordinary through or passing lane; check for any time-based reversible-lane controls.

What type of lane is indicated by the double broken yellow boundaries shown around the middle lane?
Correct answer: A lane whose permitted direction can change according to posted controls.
Double broken yellow lines can identify a reversible lane. Signs or lane-use signals govern its operation; the marking does not mean that an empty lane is automatically available.
