Signals by authorised persons

Some people can direct traffic in person, and their signals override the signs and markings around them. Police officers, traffic officers, traffic wardens and school crossing patrols all have that authority, and you must obey them: an officer directing you through a red light is giving a lawful instruction. Because these signals are given by hand rather than by machine, they are easy to misread, so it is worth knowing which arm position means stop from which direction. The same section also covers the signals you give to a person controlling traffic, so they know which way you want to go.
