Pictograms are standard on all traffic light controlled crossings. Like some other countries, a flashing red sequence is used prior to steady red to clear pedestrians. Moments after, in some instances, a flashing yellow sequence (for motorists) can begin indicating that the vehicles may proceed through the crossing if safe to do so; this is fairly uncommon however. In districts with heavier traffic warranting the use of a traffic light such as inner city areas, the equivalent of the US 'standard' configuration is used.
