Question 5
The light is red and there is no stop line. Where must you stop?
Also show inShow answer
Correct answer: Where you can still see the traffic lights, not beyond the signal pole
At red, stop at the stop line or not beyond the signal pole. With no stop line, stop where you can see the lights, and never stop on the pedestrian crossing.

Question 6
The light turns green. What does the handbook require?
Also show inShow answer
Correct answer: Move off within a reasonable time, but don't enter if you can't clear the junction
Green means you may go: start within a reasonable time. If traffic is slow or stopped and you can't cross, don't enter the junction despite the green light.

Question 15
At a pedestrian light, what does a flashing green light tell pedestrians?
Also show inShow answer
Correct answer: Those already crossing must clear the road quickly; others should not start
Flashing green means pedestrians already on the road must clear it quickly, and those approaching should not start crossing. As a driver, expect late crossers.
