WA theory test traffic lights and signs practice questions
All 8 original practice questions on this topic, with the correct answer marked and the reason under each one.
Where these questions come from
Original practice questions written for this site. Not the official question bank. They were written against the current Western Australia road rules, with the rule cited under every answer. Department of Transport does not publish the WA theory test question bank, so nothing on this page is the wording you will meet in the sitting.
How the WA theory test runs: 30 questions with 24 correct to pass, charged for each sitting. Source: Department of Transport, checked 27 August 2026.
Question 1
A traffic light turns yellow as you approach it. What must you do?
Yellow means stop unless you are so close that stopping would be dangerous. Plan for it by easing off as you approach a light that has been green for a while.
Rule cited: Drive Safe handbook (WA Department of Transport), Traffic signals
Question 2
A red arrow is showing for your turning lane while the main signal is green. What must you do?
An arrow controls its own lane. A red arrow means no turn in that direction, whatever the round signal beside it is showing.
Rule cited: Drive Safe handbook (WA Department of Transport), Traffic signals
Question 3
The light is green but traffic is banked up and there is no room for you on the far side of the intersection. What should you do?
Blocking an intersection stops cross traffic from moving when its light turns green. Only enter when you can see space to come out the other side.
Rule cited: Drive Safe handbook (WA Department of Transport), Traffic signals
Question 4
You arrive at an intersection where the traffic lights are completely dark and not working. What should you do?
Dark signals leave you with the basic give way rules, so give way to the right and to any traffic already in the intersection. Approach slowly because other drivers may not do the same.
Rule cited: Drive Safe handbook (WA Department of Transport), Traffic signals
Question 5
A green arrow pointing right is showing at a set of traffic lights. What does it mean?
A green turn arrow gives you a protected turn because the conflicting traffic is stopped. Still check for pedestrians and for any driver running the red.
Rule cited: Drive Safe handbook (WA Department of Transport), Traffic signals
Question 6
A road sign shows a symbol inside a red circle with a red line through it. What does it mean?
A red circle with a slash is a prohibition sign. Red on a sign always means something you must not do.
Rule cited: Drive Safe handbook (WA Department of Transport), Signs and signals
Question 7
You are stopped at a red traffic light and want to turn left. May you turn?
A red signal means stop and stay stopped. Turning on red is only permitted where a sign at that intersection says so.
Rule cited: Drive Safe handbook (WA Department of Transport), Traffic signals
Question 8
Twin red lights are flashing at a railway level crossing. What must you do?
Flashing red lights mean a train is coming or is already on the crossing. A second train can follow, so wait until the lights go out.
