The image is a photograph of a yellow sign attached to a metal pole. The sign is rectangular in shape and has a black exclamation mark in the center. The text on the sign reads "Do not stand near or speak to the driver except in an emergency. This is to help keep you and our drivers safe. Visit tfl.gov.uk/travel-tools." The background of the image is blurred, but it appears to be an outdoor setting with a building visible in the distance.
