24. When the road is congested, traffic on your side of the road may be  forced to stop even though their lights are green. Traffic may still  be moving on the other side of the road, so press the button and  wait for the signal to cross.  25. Toucan crossings   are light-controlled crossings which allow cyclists  and pedestrians to share crossing space and cross at the same  time. They are push-button operated. Pedestrians and cyclists will  see the green signal together. Cyclists are permitted to ride across.  26. At some crossings there is a bleeping sound or voice signal to  indicate to blind or partially sighted people when the steady green  figure is showing, and there may be a tactile signal to help  deafblind people.  highwaycodeuk.co.uk 15
