How must the driver of the car being overtaken, which is travelling with high-beam headlights during the hours of darkness, act?

• 1Switch to low-beam headlights at the moment when the cars have drawn level while travelling in adjacent lanes.
• 2Immediately switch to low beam as soon as the driver of the car behind him has begun to pull out into the oncoming lane.
• 3Turn on the headlights as soon as the car that is overtaking has appeared ahead, and travel with the marker lights on until the car travelling ahead has moved away a significant distance.
