A driver wants to go ahead at a crossroads controlled by a police officer. What recognised arm signal should they give?

Explanation: The recognised arm signal to a person controlling traffic when going ahead is shown in The Highway Code: use your left hand, held up, with the palm facing forward. This is easily distinguished by the traffic controller and allows them to control the traffic flow efficiently, keeping it moving.
