Test Your Traffic Light Junctions Knowledge

Turning right at traffic light-controlled junctions requires you to understand the difference between a steady green light and a green filter arrow, where to wait and when you need to give way to oncoming traffic.

Answer all 5 questions to check your understanding of turning right safely at traffic light-controlled junctions.

How the Knowledge Check Works

Choose the answer you think is correct. You’ll receive immediate feedback so you can identify anything you need to review.

Question 1 · Traffic Lights Turning Right

What does a circular green or steady green light mean when turning right?

A. Give way to oncoming traffic B. Stop at the stop line C. Not sure D. Just go

Correct. When turning right on a steady green light, you can proceed beyond the stop line, but you must give way to oncoming traffic before completing the turn.

Not quite. The correct answer is A — give way to oncoming traffic.

Question 2 · Green Filter Arrow

What does a green arrow or filter light mean when turning right?

A. Give way to oncoming traffic B. Stop at the stop line C. Not sure D. Just go — you have right of way

Correct. A green filter arrow allows you to proceed in the direction shown by the arrow. Continue to observe the junction and make sure your route is clear as you complete the turn.

Not quite. The correct answer is D — proceed in the direction shown by the green filter arrow.

Question 3 · Turning Point

Where should you wait when turning right on a steady green light?

A. Behind the stop line B. At the turning point C. Not sure D. Just go — you have right of way

Correct. On a steady green light, move forward to the turning point and wait there if necessary while you assess the oncoming traffic. Complete the turn when it is safe.

Not quite. The correct answer is B — wait at the turning point.

Question 4 · Yellow Box Junctions

Can you wait in the yellow box when turning right if your exit road is clear?

A. Yes B. No C. Not sure D. Wait behind the stop line

Correct. When turning right, you may enter a yellow box junction if your exit road is clear and you are prevented from completing the turn by oncoming traffic or by other vehicles waiting to turn right.

Not quite. The correct answer is A — yes, provided your exit is clear and you are waiting to turn right because of oncoming traffic or other vehicles waiting to turn right.

Question 5 · Green Filter Arrow

If the green filter arrow goes out but the steady green light remains on before you cross the stop line, what should you do?

A. Hope for the best B. Go C. Not sure D. Give way to oncoming traffic and wait at the turning point

Correct. If the green filter arrow goes out but the steady green light remains on, treat the junction as a normal right turn on a steady green light. Proceed to the turning point, give way to oncoming traffic and complete the turn when it is safe.

Not quite. The correct answer is D — give way to oncoming traffic and wait at the turning point until it is safe to turn.

Review What You’ve Learned

If you answered any questions incorrectly, make sure you understand the difference between a steady green light and a green filter arrow rather than simply memorising the correct answer.

You can revisit traffic light-controlled junctions in the NSOM Academy and then put these techniques into practice during your next driving lesson.
