When are you required to turn on the direction indicators and signal?

1. When you approach a railway crossing or a pedestrian crossing.
2. Only before a sharp curve.
3. Only when you make left hand turns in intersections.
4. Correct answer: When you are about to start driving or to turn your vehicle, or to deviate from your lane.

WhyYou signal when you pull away, turn or change lanes. Not only to the left and not only before a sharp turn.
