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 a Tennessee 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.

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.
The right-side line bends toward the continuing lane, indicating a reduction in lanes. This is a lane-ending warning, not traffic entering from a separate roadway.

What does the pair of arrows pointing in opposite directions warn you about?
Correct answer: Traffic moving in both directions on the roadway.
The downward and upward arrows identify two-way traffic. Do not interpret them as two same-direction lanes or a turn-choice sign.
