APPENDIX.
TRAFFIC SIGNALS THAT EVERY ROAD USER SHOULD KNOW.
PART I.
SIGNALS TO BE GIVEN BY POLICE
CONSTABLES AND OTHERS ENGAGED IN
THE REGULATION OF TRAFFIC.
THE following signals are those officially recommended and are intended to cover the ordinary situations which arise in traffic control, but other signals may be required for abnormal situations or owing to the peculiar lay–out of particular road junctions.
Drivers should note that once they have been stopped the constable may lower his hand or use it for giving other signals. They should not move on until the constable signals to them to do so.
Signals Nos. 1 to 4 are specially illustrated to show how, in a simple instance, they appear to the drivers for whom they are intended. It makes no difference if, as will often happen, the constable’s other arm is engaged in making another signal.
An illustration is also given of "Stop" Signals Nos. 1 and 2 combined. Other signals may also be used incombination such as "Stop" Signal No. 1 or No. 2 and "Proceed" Signal No. 4.
Drivers should be specially careful to distinguish the "Proceed" signal intended for them from those intended for other traffic. This will be shown primarily by the constable looking in their direction. In particular, they should note that no "Proceed" signal applies to a driver towards whom the constable's back is turned.
"Proceed" Signals are used not only to bring on vehicles which have been stopped, but also to indicate to approaching vehicles that their way is clear.
