Never cross  the road directly behind or in front of a bus. Wait until it has  moved off and you can see clearly in both directions.  33. Tramways.   These may run through pedestrian areas. Their path will  be marked out by shallow kerbs, changes in the paving or other  road surface, white lines or yellow dots. Cross at designated  crossings where provided. Elsewhere treat trams as you would  other road vehicles and look both ways along the track before  crossing. Do not walk along the track as trams may come up behind  you. Trams move quietly and cannot steer to avoid you.  34. Railway level crossings.   You MUST NOT   cross or pass a stop line  when the red lights show, (including a red pedestrian figure). Also  do not cross if an alarm is sounding or the barriers are being  lowered. The tone of the alarm may change if another train is  approaching. If there are no lights, alarms or barriers, stop, look  both ways and listen before crossing. A tactile surface comprising  rounded bars running across the direction of pedestrian travel may  be installed on the footpath approaching a level crossing to warn  visually impaired people of its presence. The tactile surface should  extend across the full width of the footway and should be located  at an appropriate distance from the barrier or projected line of the  barrier.  35.
