What does the broken yellow center line in this road diagram allow?
Correct answer: Passing from either direction when conditions permit it safely.
A broken yellow center line permits crossing to pass with care from either direction. The line does not promise clear sight distance, a safe gap or freedom from other passing restrictions.

The center marking has one broken and one solid yellow line. If the broken line is nearest your lane, what does the marking mean for passing?
Correct answer: You may cross to pass when it is safe and otherwise permitted.
With a broken-and-solid yellow pair, permission depends on your side. Traffic beside the broken line may cross to pass with care; traffic beside the solid line may not cross to pass.

What passing restriction is communicated by these two solid yellow center lines?
Correct answer: Crossing them to pass is prohibited in both directions.
Double solid yellow center lines mark a no-passing restriction for both directions. This question concerns passing, not whether some other separately authorized movement may cross a center line.

In this four-lane diagram, what do the white lane lines separate?
Correct answer: Lanes carrying traffic in the same direction.
White longitudinal lane lines separate same-direction traffic. The yellow center lines divide the opposing traffic streams shown by the black direction arrows.

What kind of lane is indicated by the double broken yellow markings on both sides of the middle lane?
Correct answer: A lane whose direction of travel can be reversed.
Double broken yellow lines border a reversible lane. Signs, lane-control signals or both establish its permitted direction; the arrows in the source diagram show alternative use, not simultaneous opposing traffic.

What does the middle lane with opposed turn arrows and broken-yellow-inside, solid-yellow-outside borders indicate?
Correct answer: A two-way left-turn lane shared by opposing approaches.
The broken yellow line faces into the two-way left-turn lane and the solid yellow line faces adjacent through traffic. The opposed turn arrows distinguish this shared turn lane from a reversible through lane.

What do the paired solid white lane lines in this detail mean?
Correct answer: Do not cross the pair to change lanes.
A double solid white lane line prohibits crossing. It is a stronger restriction than a single solid white lane line, which discourages crossing.

What does this row of solid white triangles across a lane mark?
Correct answer: The point at which approaching traffic is to yield.
A yield line consists of solid white triangles pointing toward approaching traffic. It identifies the yielding point and is different from a solid rectangular stop line or a large outlined yield-ahead triangle.

What does this symbol painted in a parking space identify?
Correct answer: A space designated for parking by persons with disabilities.
The International Symbol of Accessibility identifies designated accessible parking. An empty marked space is not general overflow parking. Follow the applicable authorization requirements and posted restrictions.

What does this slanting lane-reduction arrow tell a driver?
Correct answer: The lane is ending and traffic needs to move toward the indicated lane.
A lane-reduction arrow warns of the need to leave a lane that is ending. Plan the merge, check surrounding traffic and find a safe gap; the arrow does not give you priority.

Which movement choice does this combined lane-use arrow represent?
Correct answer: Continuing through or taking the indicated turn.
A combined turn-and-through arrow indicates both movements from that lane. It is not the same as a turn-only arrow. The official figure illustrates the arrow shape in black.

What movement is represented by this lane-use arrow shape?
Correct answer: A U-turn.
The curved-back arrow is a U-turn lane-use marking, not a lane-change arrow. Follow the controls for the lane and give way as required; the marking is not a guarantee that a gap is safe.

Two freeway lanes traveling in your direction are separated by a normal broken white line. How should you interpret it?
Correct answer: You may change lanes across it when the move is safe.
A normal broken white lane line permits crossing with care between same-direction lanes. It does not replace checking mirrors and blind spots or yielding to traffic already in the other lane.

A single solid white lane line replaces the broken white line between two same-direction lanes. What change in meaning does it convey?
Correct answer: Crossing the line is discouraged.
The standard meaning of a single solid white lane line is that crossing is discouraged. A double solid white line prohibits crossing. Other signs and restrictions still apply.

On an ordinary roadway without special part-time-shoulder controls, which line normally marks its right-hand pavement edge?
Correct answer: A solid white line.
The normal right-edge pavement marking is solid white. Do not confuse the road edge with a broken white line separating two usable same-direction travel lanes.

Which color normally marks the left-hand pavement edge of a divided highway or one-way ramp?
Correct answer: Yellow.
The normal left-edge line on a divided highway, one-way street or ramp is yellow. This is an edge-line application, not a broken-yellow permission to pass opposing traffic.
