Facts
Turn signals are there to signal to other people in traffic what you intend to do. Remember to first look before you blink, so that you are free to do the manoeuvre you intended.
You are obliged to turn or signal when you:
You do not have to blink when you stop because there is a risk that others may think that you are going to turn if you have an intersection or entrance nearby. If there is no intersection or entrance nearby, however, it can be clarifying to blink your way to the edge to stop. In the event of an accident or if the car breaks down and you are forced to stop in a place where you may pose a danger or obstacle to other traffic, it is important that you use hazard warning lights. You then tell other road users that you really need to stop where you are.
When you turn on your hazard lights, all your turn signals flash at the same time and you can hear the same ticking sound as with a normal indicator.
