You intend to turn left at the crossroads. Must you signal this manoeuvre with a left turn signal?

In the video you are approaching a junction in a housing estate in town; on the right there are signs D-1 "priority road" with plate T-6a and D-6 "pedestrian crossing", and on the traffic island there is C-9. Since you intend to turn left, you are required to signal this manoeuvre with the left indicator. The answer is: yes.

The Road Traffic Act requires a driver to signal an intention to change direction or change lanes with the indicator in good time and clearly, and to stop signalling immediately after completing the manoeuvre. A left turn is a change of direction, so the left indicator is always required, whether you are on a priority road or a minor road, and whether or not the junction is empty. In a housing estate, it tells above all pedestrians on the crossing and oncoming drivers that you will cross their path. Before turning, you move towards the middle of the roadway and give way to vehicles coming from the opposite direction that are going straight on or turning right, and when turning into the intersecting road, you give way to pedestrians crossing the roadway you are entering. Sign C-9 on the traffic island reminds you that you pass the island on its right side. You switch on the indicator several dozen metres before the junction, not at the moment you turn.
