When must the driver activate the visual warnings to signal a maneuver?

Question

DentroTest · Accepted Answer

The General Traffic Regulations establish that every driver must give visual warning signals of any maneuver involving a lateral movement or reversing, as well as of their intention to bring the vehicle to a stop or to slow down considerably (Article 109(1)). These warnings are given sufficiently in advance of the start of the maneuver, so that other road users perceive the intention and can adapt their driving. Warning at the very moment the movement begins does not give that reaction time. And the obligation is not limited to drivers on an emergency call: it applies to all drivers.
