Green, amber and space beyond the junction

Reason from the conditions, not from a memorised answer. Read the scene, choose, then open the explanation. The drawing is illustrative; the written conditions control the question.

Before entering on green, check that the exit has room for your vehicle. A green light is permission to proceed under the remaining rules, not permission to block the junction.

At steady amber, stop before the line if you can do so safely. The exception concerns being too close to stop safely when amber appears; it is not a general allowance to accelerate through.

Flashing amber calls for special care and does not itself give priority. Apply the signs that govern the junction. A STOP sign still requires a full stop even when you can see no traffic.

Question 1 · Advanced scenarios

Your light is green. The queue beyond the junction leaves less space than your car needs, so entering would probably leave you stopped on the junction. What do you do?

**Green light with a queue beyond the junction**Blue car: you. Gold car: other traffic. Diagram not to scale; use the written conditions.

Wait before entering until the exit has enough room.
Enter and wait in the junction because green grants access.
Enter if I can keep the pedestrian crossing behind me clear.

Show the answer and explanation

Correct answer: A

The exit-space condition controls this decision. Green does not permit entry likely to block the junction. Keeping only the zebra crossing clear is insufficient if your car would still obstruct the junction.

Question 2 · Advanced scenarios

The light changes to steady amber before you reach the stop line. You have enough distance to stop smoothly and safely. What is required?

**Steady amber before the stop line**Blue car: you. Gold car: other traffic. Diagram not to scale; use the written conditions.

Continue if I can cross the line before red appears.
Continue at the same speed because braking is not yet urgent.
Stop before the stop line.

Show the answer and explanation

Correct answer: C

The unsafe-stop exception does not apply: the question explicitly says a safe stop is possible. Beating the red light is not the test. Stop progressively before the line.

Question 3 · Advanced scenarios

Junction lights flash amber. A STOP sign applies to your approach. You have a clear view and see no other traffic. What must you do?

**Flashing amber and a STOP sign**Blue car: you. Gold car: other traffic. Diagram not to scale; use the written conditions.

Slow down without stopping because flashing amber replaces STOP.
Stop completely at the prescribed place, then give way as necessary before proceeding.
Stop only if traffic appears before I reach the junction.

Show the answer and explanation

Correct answer: B

Flashing amber does not suspend the STOP sign. STOP requires full standstill, unlike merely giving way when needed. An empty view does not remove the mandatory stop.
