At a pelican crossing, what must you do when the amber light is flashing?

Explanation: Pelican crossings are signal-controlled crossings operated by pedestrians. Push-button controls change the signals. Pelican crossings have no red-and-amber stage before green. Instead, they have a flashing amber light, which means you MUST give way to pedestrians already on the crossing, but if it is clear, you may continue.
