Stop well before the stop line, and don't crowd the intersection. This not only obstructs a clear view of the intersection for other road users, but also make the zebra crossing unsafe for the pedestrians. You are allowed to turn left at the red signal unless there is a sign specifically forbidding you to do so. When turning, yield the right of way to pedestrians and vehicles from other directions.
The Amber light gives time to vehicles to clear the road when the signal is changing from green to red. If caught in the Amber signal in the middle of a large road crossing do not press your accelerator in panic but do continue with care.
If first in line, do not go tearing off at the green signal but pause to see whether vehicles from other directions have cleared the road.
Sometimes you are allowed to turn left or right too, unless separate signs exist for each direction. If turning, yield the right of way to pedestrians and vehicles from other directions.
STEADY GREEN ARROW SIGNAL
Proceed with caution in the direction indicated by the arrows. Remember that you must yield to all pedestrians and vehicles already in the intersection.
FLASHING RED SIGNAL
You must come to a complete stop, yield to all other traffic and to pedestrians. Proceed only when the way is clear.
FLASHING AMBER SIGNAL
You should slow down and proceed with caution.
