How should one indicate a left turn with their arms?

Why that is the answer

To signal a left turn using arm signals, extend your right arm out of the window and move it in a circular motion. This clearly shows other road users and traffic controllers that you intend to turn left if your indicators fail. Extending your arm straight out signals a right turn, while moving it up and down indicates that you are slowing down or stopping. These standard signals are shown in the Highway Code.

How this comes up in the real test

Questions from road and traffic signs appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.

The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
