Which the control lights visible in the illustration informs you that the direction indicators are enabled?

The illustration shows three green warning lights: A - two arrows, left and right, B - a sidelight symbol, C - a headlamp with rays pointing downwards, that is, dipped headlights. Light A shows that the indicators are on - answer A.

The Regulation on the technical conditions of vehicles requires a vehicle to have a control signal showing that the indicators are working - this may be a flashing green light signal, a sound signal, or both at the same time. That is why in a car the green arrow flashes in time with the indicator, usually with a typical clicking sound; the left arrow corresponds to the left indicator, the right arrow to the right one, and with hazard warning lights both flash, together with a red warning light with a triangle. The Regulation also provides that when one of the indicators stops working, the control signal should go out, stay lit or flash at a clearly changed frequency - that is why fast flashing of the arrow means a blown bulb. The Road Traffic Act requires you to signal your intention to change direction or lane in good time and clearly, and to stop signalling right after the manoeuvre - the flashing light reminds you that your indicator is still on.
