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.

The pictured sign faces your car at a ramp entrance. Is the ramp available to you from this end?

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?

The pictured arrow and ONLY sign is above your lane. Which movement is required 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.

What does the number on this white SPEED LIMIT sign represent?

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.

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.

You are traveling in the right lane when this sign appears. What roadway change does it warn of?
Correct answer: The right lane ends ahead.

What does the pair of arrows pointing in opposite directions warn you about?

What does the 1000 FT on this orange sign tell you?
