The normal movement of a vehicle within the flow of traffic is simply to adapt to the general pace of that flow, without relative changes in position. On the road, this is normal progression. If we interrupt this normal progression to change our situation or position, we are performing a manoeuvre. Whenever we are about to perform a manoeuvre, we must warn other road users of our intention to do so, clearly and with sufficient advance notice, using light signals or, failing that, the arm.
