Every question and its answer choices. The correct answers and explanations appear when you take the test above.
Where are lane control signals most often used?
- On reversible lanes
- At four-way stops
- At railway crossings
- In school zones
On a vertical traffic signal, where is the red light?
- On the left side
- At the top
- In the middle
- At the bottom
You see a steady red X over the lane you are driving in. What must you do?
- Turn on hazard lights and continue
- Move safely to a lane with a green arrow
- Stay in the lane and slow down
- Stop in the lane right away
You have a steady green light and want to turn left. What must you do?
- Sound your horn and turn
- Wait for the light to turn amber
- Yield to vehicles and people lawfully in the intersection
- Turn first, since the green light gives you the right of way
On a horizontal traffic signal, which light is on the far right?
- Green
- The arrow
- Amber
- Red
You are stopped at a red light and want to turn right. No sign prohibits it. What may you do?
- Turn only with a green arrow
- Turn without stopping if the way is clear
- Turn after a full stop, yielding first
- Wait for the green light
When may you turn left on a red light in the NWT?
- Only when a green arrow is also lit
- From a two-way street onto a one-way street, after stopping
- From any street when no traffic is coming
- From a one-way street onto a one-way street, after stopping
You face a steady green arrow pointing straight ahead. What may you do?
- Turn in any direction
- Turn right or go straight
- Turn left after yielding
- Go straight only
A downward-pointing green arrow is lit over your lane. What does it mean?
- This lane is closing ahead
- This lane is for buses only
- Turn left from this lane
- You may drive in this lane
What is the purpose of a steady amber light?
- To allow turns from any lane
- To let pedestrians start crossing
- To warn that the light will turn green
- To clear the intersection safely
You face a double red light. How should you treat it?
- As a flashing red light
- As a red light for trucks only
- The same as a single red light
- As a sign that the signal is broken
You face a steady red light. There is no stop line or crosswalk. Where must you stop?
- Beside the signal pole
- In the middle of the intersection
- Past the first crosswalk
- Before entering the intersection
As you approach a green light, the pedestrian signal changes from walk to don't walk. What does that suggest?
- Pedestrians have the right-of-way
- You must stop immediately
- The light will stay green longer
- The light may soon turn amber
You face a red light together with a flashing green arrow pointing left. What may you do?
- Wait until the red light changes
- Turn left without stopping, but yield if needed
- Go straight or turn left
- Stop fully, then turn left only once the way is clear
What does a flashing amber light at an intersection require?
- Go with caution after yielding
- Speed up to clear the area
- Stop completely, then go
- Stop and wait for green
A pedestrian began crossing on a walk signal, and the signal changes to don't walk. What may the pedestrian do?
- Return to the starting curb
- Finish crossing
- Wait for traffic to stop
- Stop in the middle of the road
The light turns amber as you approach. You can stop safely before the stop line. What should you do?
- Stop inside the intersection
- Speed up to clear the intersection
- Continue at the same speed
- Stop before the stop line
You face a flashing green light. Opposing traffic has a red. What must you still do?
- Yield to pedestrians and vehicles in the intersection
- Nothing, since the flashing green gives you full right-of-way
- Stop before going straight
- Turn right only
You come to a flashing red light at an intersection. What must you do?
- Go if no one is directly ahead
- Stop, then go only when it is safe
- Slow down and go with caution
- Stop and wait until it turns green
Traffic lights and signals: key rules to remember
Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
Traffic control signals (Ch. 2 Traffic Controls)
- Signals assign right-of-way between conflicting traffic streams at an intersection; they can be vertical or horizontal.
- Vertical order: red top, amber middle, green bottom. Horizontal order: red left, amber middle, green right.
Steady red and steady amber
- Steady red (a double red means the same as a single red): stop before the stop line or crosswalk on the near side; if neither, stop before entering the intersection; stay stopped unless directed or permitted.
- Right turn on red is allowed after a full stop unless a sign prohibits it.
- Left turn on red from a one-way street onto a one-way street is allowed after a complete stop unless a sign prohibits it.
- A pedestrian facing a steady red must not enter unless another pedestrian signal permits.
- Steady amber: stop before the stop line or crosswalk (or before the intersection) unless you cannot stop safely. Amber is there to clear the intersection safely. Pedestrians facing amber must not start crossing unless another pedestrian signal permits.
Steady green; steady green arrow
- Steady green: go straight or turn right or left unless a movement is prohibited. Turning vehicles must yield to vehicles and pedestrians lawfully in the intersection.
- A green that has been on a long time may soon turn amber; if it changes you must stop. A pedestrian signal changing from walk to don't walk is a clue the light is about to change.
- Pedestrians facing a steady green may cross within any marked or unmarked crosswalk unless another pedestrian signal directs otherwise.
- Steady green arrow: enter only to go in the arrow's direction.
Flashing lights
- Flashing green arrow (left or right): you may enter and turn the way the arrow points; with a red light showing too you may turn without stopping. Can be used with a steady green. Yield to all pedestrians and vehicles in the intersection.
- Flashing red: stop before the stop line or crosswalk (or before the intersection); go only when safe — treat like a stop sign.
- Flashing amber: go with caution after yielding to pedestrians and vehicles lawfully in the intersection.
- Flashing amber with a school zone, playground zone, school crossing, pedestrian crossing or other pedestrian-hazard sign: reduce speed as posted and yield to all pedestrians.
Flashing green; pedestrian signals; lane control signals
- Flashing green: you may go straight, left or right; opposing traffic faces a red light, but you must still yield to pedestrians and vehicles lawfully in the intersection.
- Walk signal: pedestrians may enter the crosswalk in the direction of the light.
- Wait / don't walk signal: pedestrians must not start crossing; those who began legally may finish.
- Lane control signals control direction of travel lane by lane, most often in reversible lanes.
Lane control signals
- Steady red X over a lane: do not enter or stay in that lane; it will be used by oncoming traffic. Move safely to a green-arrow lane.
- Downward-pointing green arrow: you may drive in that lane.
