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.

A short, closely spaced dotted white line separates your lane from the continuing freeway lane beside it. What possibility should you check?
Correct answer: Your lane may be an exit or acceleration lane that does not continue.
Dotted white lane markings distinguish non-continuing lanes such as deceleration or acceleration lanes from continuing through lanes. Check lane-use signs and your route early instead of assuming every lane continues.

While turning through a large intersection, you see dotted white lines continuing the lane path. What are they for?
Correct answer: Guiding traffic along the intended path through the intersection.
Dotted line extensions guide vehicles through intersections and other complex transitions. Follow your lane path and the right-of-way controls; the extension itself grants no priority.

At a stop-controlled approach, what does a solid white line drawn across your lane identify?
Correct answer: The point behind which your vehicle must stop.
A stop line is a solid white transverse marking identifying the stopping point. Stop behind it rather than rolling over it to reach the intersection.

How is a large outlined triangular pavement symbol different from a row of small solid white triangles?
Correct answer: The large outline warns of a YIELD control ahead.
The large outlined triangle is a yield-ahead warning used on an approach to an intersection with a YIELD sign. A row of solid white triangles is a yield line identifying the yielding point.

Your lane has a right-turn arrow and the word ONLY painted on the pavement. What movement is indicated?
Correct answer: A required right turn from that lane.
ONLY with a turn arrow indicates a mandatory turn lane. Choose the correct lane early; this is different from a combined through-and-turn arrow.

At night on a one-way ramp, the raised pavement markers facing you reflect red. What should that warn you about?
Correct answer: You may be traveling in the wrong direction.
Red raised pavement markers can warn of wrong-way travel on a one-way roadway, ramp or lane. This scenario specifies a one-way ramp: red markers are also used for truck escape ramps, so red is not an identical message in every setting.

A painted median separating opposing traffic contains yellow diagonal stripes. What is the intended message?
Correct answer: The striped space is not an ordinary travel lane.
Diagonal markings help discourage travel in neutral areas and painted medians. Yellow diagonals are used where the adjacent traffic streams run in opposite directions, among other specified applications.

White V-shaped chevrons fill a neutral area between lanes moving in the same direction. What should you understand?
Correct answer: They discourage driving through that marked neutral area.
White chevrons emphasize a neutral or buffer area rather than a normal travel lane. A specific location may carry an additional legal prohibition, such as Arizona’s gore-area rule.

You notice a painted curb in an unfamiliar Arizona city. What is the best basis for deciding whether parking is allowed?
Correct answer: The applicable parking rules and signs, not an assumed universal color code.
Curb colors can supplement local parking regulations or improve visibility. The MUTCD recognizes local color specifications; do not import another state’s entire curb-color system or assume an unpainted curb means parking is legal.

One marked crosswalk has two lines across the road; another has a ladder pattern. What do both identify?
Correct answer: A designated path for pedestrians to cross the roadway.
Crosswalk designs include two transverse lines and high-visibility bar or ladder patterns. Different patterns do not make one a parking area or remove the need to watch for pedestrians.

What type of preferential lane is identified by a white diamond pavement symbol?
Correct answer: A high-occupancy-vehicle lane.
The white diamond is the HOV lane pavement symbol. Read the accompanying signs for occupancy, operating hours and other applicable eligibility rules; the diamond does not specify those details by itself.

You miss the start of an exit ramp. May you drive across the gore area bounded by two wide solid white lines to catch the exit?
Correct answer: No; continue on and take a lawful route back.
Arizona prohibits driving over or across a gore area. Missing an exit does not create an exception. Continue safely rather than cutting across the ramp’s separation area.

Your car works normally, but you want to park in a freeway gore area to check a route on your phone. Is that permitted?
Correct answer: No; a gore area is not a normal parking place.
Arizona’s gore rule prohibits parking any part of a vehicle there. Its narrow exception concerns a disabled vehicle when stopping or temporarily leaving it elsewhere cannot be avoided, not a routine phone or navigation stop.

An intersection area has white crosshatching and a DO NOT BLOCK instruction. What is the purpose of these markings?
Correct answer: To identify space that traffic must leave unblocked.
DO NOT BLOCK markings and accompanying signs identify an area that must remain clear. An outline, crosshatching or word message may be used; it is not a holding area for a queue.

The yellow line nearest you is solid, while the line beside opposing traffic is broken. Can you cross the pair to overtake a slow vehicle?
Correct answer: No; the solid line on your side prohibits crossing to pass.
Read the line adjacent to your lane. A broken line beside opposing traffic does not grant you permission to pass across the solid line beside your lane.

You recognize double broken yellow borders around a reversible lane. What tells you whether that lane is available in your direction now?
Correct answer: The signs or lane-control signals for the reversible lane.
A reversible lane’s markings identify the type of lane, not its current operating direction. The MUTCD requires supplemental signs, lane-control signals or both to control that use.
