Turn indicators

Rule: Use the turn indicator to signal when you are leaving the main traffic lane, not when the road changes direction. Turn indicators can be used to tell traffic behind you where to overtake.

Traffic Logic: Use turn indicators to signal your intentions to other road users, especially those behind you. Example: If the main road makes a right turn and there is a small side road continuing straight, you do not need to use the right turn indicator if you are on the main road. However, if you plan to take the small road, going straight, you should give a left turn indication.

On a straight road, the vehicle in front should signal right if it wants the following vehicle not to overtake (wait for ‘side’). To tell the following vehicle to overtake (from the right), it should signal left, not right. Truckers often get this wrong.
