How many work zone signs are on the test?

This group has 6 signs. Sign questions are typically about a third of the written test.

An orange sign at the roadside means:

You are approaching a work zone, where fines are often doubled

The road ahead is closed to all traffic

There is a scenic or recreational area ahead

An orange sign tells you that:

You are entering a temporary traffic control or work zone

You are driving on a highway and see this sign. What should you expect ahead?

Construction or maintenance work is going on ahead

The road ahead is permanently closed to through traffic

A permanent change in the road's alignment begins here

A parking area for highway maintenance vehicles

This sign means that ahead:

Both directions must share a single lane, alternating

Your lane will end and you should merge

The road narrows but stays two-way

One lane is closed to trucks only

This sign appears on a two-way road. What should you be prepared to do?

Give way to oncoming traffic and stop if needed before using the single open lane

Merge left because your lane ends permanently

Drive on the shoulder to get past the work area

Keep your normal speed, since each direction still has a lane

Ahead of you a flagger holds up a paddle. Whose instruction takes priority?

The flagger — their directions override signs and signals

The traffic signal at the next intersection

Whichever came first along the road

This sign is posted before a work zone. When you reach the person it shows, what governs your movement through the zone?

The flagger's directions, even where they differ from the posted signs

The posted speed limit sign only

The traffic signal at the next intersection

Whatever the vehicle ahead of you does

What is the correct response to this sign?

Slow down, watch for people on or beside the roadway, and be ready to stop

Move onto the shoulder so the crew can use the travel lane

Sound your horn to alert the crew as you pass

Hold your speed, since workers are always behind a barrier

An orange DETOUR sign directs you to:

A marked alternative route around a closure

A truck route you may optionally use

A road that is open only to local traffic

What does this sign tell you to do?

Leave the normal route and follow the marked alternative in the direction of the arrow

The road ahead is under construction but still open to through traffic

There is a rest area in the direction of the arrow

1.
An orange sign at the roadside means:
Not quiteCorrect answer: B — You are approaching a work zone, where fines are often doubled
Orange is reserved for temporary traffic control in construction and maintenance zones. Expect workers, lane shifts and reduced speed limits; many states double the fines for violations inside a work zone.
Orange does not mean the road is closed — it means conditions have temporarily changed.
2.
An orange sign tells you that:
Not quiteCorrect answer: C — You are entering a temporary traffic control or work zone
Orange is reserved for temporary traffic control. It means the road is not in its normal condition: workers, equipment or a changed lane pattern may be ahead.
Orange is often lumped in with yellow as "warning". Yellow warns about a permanent feature of the road; orange means the situation is temporary and people may be working in it.
3.
You are driving on a highway and see this sign. What should you expect ahead?
Not quiteCorrect answer: C — Construction or maintenance work is going on ahead
Orange is used only for temporary traffic control. Crews, equipment, lane shifts or a flagger may be ahead, so the pattern you are used to on this road may not be the pattern you meet.
Reading road work as road closed. The route normally stays open through a work zone; it is the conditions in it, not the road, that change.
4.
This sign means that ahead:
Not quiteCorrect answer: B — Both directions must share a single lane, alternating
Only one lane is open and traffic takes turns, usually under a flagger or pilot car. You may have to wait for oncoming traffic to clear.
Treating it as a normal merge and racing to be first is how head-on conflicts happen in work zones.
5.
This sign appears on a two-way road. What should you be prepared to do?
Not quiteCorrect answer: D — Give way to oncoming traffic and stop if needed before using the single open lane
Both directions of travel have to share one lane through the work area, so the traffic alternates. A flagger or a pilot vehicle usually controls whose turn it is, and your turn may mean waiting.
Reading ONE LANE ROAD as one lane in each direction. It means one lane in total, used by traffic coming both ways.
6.
Ahead of you a flagger holds up a paddle. Whose instruction takes priority?
Not quiteCorrect answer: C — The flagger — their directions override signs and signals
A flagger directing traffic has authority over signs and signals in the work zone. They can see the equipment, the workers and the oncoming lane; the signs cannot.
Drivers hesitate when a flagger waves them through a red light or past a stop sign. Following the person in the vest is correct.
7.
This sign is posted before a work zone. When you reach the person it shows, what governs your movement through the zone?
Not quiteCorrect answer: A — The flagger's directions, even where they differ from the posted signs
A flagger is placed to direct traffic through a work zone, and their instructions take priority over the signs and markings there. The flagger can see the oncoming lane, the equipment and the crew that you cannot.
Treating the flagger's paddle as advice that a green signal or a posted sign overrides. Disobeying a flagger is disobeying a traffic control device.
8.
What is the correct response to this sign?
Not quiteCorrect answer: B — Slow down, watch for people on or beside the roadway, and be ready to stop
People on foot may be working within a step of the travel lane, and equipment can back into it without warning. Slowing is what buys you the reaction time to avoid someone who moves unexpectedly.
Believing cones or drums protect the crew. They mark the zone; they stop nothing, and many work zones have no barrier at all.
9.
An orange DETOUR sign directs you to:
Not quiteCorrect answer: A — A marked alternative route around a closure
A detour is a signed route around a closed section. Following the whole sequence of detour signs matters — leaving it partway usually strands you at the closure.
Navigation apps often try to route back to the closed road. The posted detour reflects a closure the map may not know about.
10.
What does this sign tell you to do?
Not quiteCorrect answer: C — Leave the normal route and follow the marked alternative in the direction of the arrow
A detour routes traffic around a section that is closed or blocked. Its orange background marks the arrangement as temporary, and further detour signs will carry you through each turn back to the normal route.
Turning off and then navigating your own way back. The detour is a signed sequence; leaving it usually means losing the route entirely.
