Highway Code Rule 199

Toucan, puffin and equestrian crossings. These are similar to pelican crossings, but there is no flashing amber phase; the light sequence for traffic at these three crossings is the same as at traffic lights. If the signal-controlled crossing is not working, proceed with extreme caution. Do not enter the crossing if you are unable to completely clear it, to avoid obstructing pedestrians, cyclists or horse riders.
