Question image: When you are about to be overtaken, do you have to signal?
  • A Yes, you must always signal
  • B Yes, by switching on the hazard warning lights to show it is safe
  • C No, under no circumstances
  • ✓ Only drivers of heavy or large vehicles, or vehicles subject to a specific speed limit, when they cannot pull fully to the right and the overtaking can be done safely

Why this is the correct answer

Under Article 86.1 of the General Traffic Regulations, every driver who is about to be overtaken must keep to the right-hand edge. If they cannot keep fully to the right and the overtaking can be done safely, drivers of heavy or large vehicles, or vehicles subject to a specific speed limit (Art. 86.3), must show the driver behind that it is possible, by arm signal or with the right indicator. Other drivers are not required to signal.
