Puffin crossings have sensors that determine when the crossing is clear. The signal to change from red, to red/amber, and then to green is automatically triggered at that point. If the pedestrians at the crossing cross the road before getting the green man signal the request to stop traffic is automatically cancelled.

What light follows green at a Puffin crossing?

Explanation: Puffin crossings have infra-red sensors that detect when pedestrians are crossing and hold the red traffic signal until the crossing is clear. The use of a sensor means there's no flashing amber phase as there is with a pelican crossing.

What is the sequence and meaning of the lights at a pelican crossing?

Pelican Crossings are the crossings which are signal-controlled crossings where flashing amber follows the red 'Stop' light. ... If the amber light is flashing and there are no pedestrians on the crossing, you may proceed with caution. After the lights start flashing, watch out for people making a last-minute dash.
