A red octagonal sign faces your lane at an ordinary intersection. Which response does it require?
Correct answer: Bring your vehicle to a complete stop.
STOP requires a full stop. The eight-sided red sign is the control at the intersection, not a warning that a stop is farther ahead.

Crossing traffic has priority as you approach this triangular sign. What should you do?
Correct answer: Slow down and stop if needed to give way.
YIELD means give way to conflicting traffic. Slowing may be sufficient, but you must stop when necessary to avoid interfering with traffic that has priority.

The pictured sign faces your car at a ramp entrance. Is the ramp available to you from this end?
Correct answer: No; entry from this direction is prohibited.
DO NOT ENTER is used to prevent entry in the wrong direction. An empty ramp or a navigation instruction does not make entry permitted.

Which maneuver is prohibited by the arrow and red slash in this sign?
Correct answer: Turning around to travel in the opposite direction.
The curved arrow that doubles back, crossed by a red circle and slash, means No U-Turn. Do not confuse it with the angled arrow on a No Left Turn sign.

At an intersection with this sign and no exception plaque, which choice is prohibited?
Correct answer: Making a right turn from this approach.
The red slash crosses a right-turn arrow. It prohibits that turn from the approach; waiting for a gap does not remove the restriction.

The sign shown applies to your intersection approach. What is its message?
Correct answer: Do not make a left turn here.
A left-turn arrow under a red circle and slash prohibits a left turn. A required-turn sign instead shows an uncrossed arrow and the word ONLY.

What does this plain rectangular sign prohibit at the intersection?
Correct answer: Turning movements from this approach.
NO TURNS is a movement-prohibition sign. It is not an instruction to stop and then turn, and it is not limited to a particular one-way destination.

The pictured arrow and ONLY sign is above your lane. Which movement is required from that lane?
Correct answer: Turn left through the intersection.
A mandatory lane-control sign specifies one required movement. The left arrow with ONLY designates a left-turn-only lane, not an optional through lane.

An upward arrow with ONLY is posted over your lane. How must that lane be used?
Correct answer: Proceed straight through the intersection.
The straight arrow with ONLY designates a through-only lane. It does not grant permission to make a turn from that lane.

This sign is above a single approach lane. Which movements does it allow from that lane?
Correct answer: Straight ahead or left.
The two arrow branches indicate the permitted movements: straight and left. It is an optional-movement sign, so the lane is not restricted to only a left turn.

You are in the left lane as you reach the intersection governed by this sign. What must that lane do?
Correct answer: Make the indicated left turn.
LEFT LANE MUST TURN LEFT designates the required movement for the left lane. A green signal does not turn it into a through lane.

What does the number on this white SPEED LIMIT sign represent?
Correct answer: The posted maximum speed in miles per hour.
A SPEED LIMIT sign states the legal speed limit, not a curve advisory or a route distance. The number shown is an example of a posted limit, not an Arizona statewide default.

This MINIMUM SPEED 40 plaque is mounted beneath a speed-limit sign. What does the 40 identify?
Correct answer: The posted minimum legal speed in mph.
A MINIMUM SPEED plaque identifies the posted minimum legal speed and is used with a maximum-speed sign. It is not a night limit or a curve advisory. The illustration shows only the plaque.

What should you expect beyond the pictured warning sign on the main road?
Correct answer: Traffic from the right joins a shared lane.
The branch joining the main arrow indicates a merge from the right. Unlike an Added Lane sign, it warns that the converging traffic will share a lane.

How does this sign differ from a merge warning?
Correct answer: The entering roadway adds a separate lane.
The two distinct arrows separated by a dashed line indicate an added lane. The roadways converge without requiring a merge at that point.
