Traffic lights in Europe

Red light: do not cross the stop line or pass the light.

Yellow light precedes the red light: stop unless you are already too close to stop safely.

Red and yellow lights together: lights are about to change to green; get ready to go but don't set off until the green light is on.

Green light: drive on, provided the way is clear.

Green arrow beside the red light: you may turn in the direction of the arrow provided that you shall stop before the traffic lights and shall not cause an obstruction to other participants.
