Obligations of those overtaking during the maneuver

Article 85. Obligations of those overtaking during the maneuver.
1. Whilst overtaking, the driver who does so must travel at a speed significantly faster than those he tries to overtake and must leave between both a lateral separation sufficient to do so with safety (LST Art 34,1).
2. If, after starting to overtake he notices that the situation makes overtaking difficult without risk, he will reduce his speed quickly and return to his lane and so indicate to those following with the mandatory signals (LST Art 34,2).
3. The driver of the overtaking vehicle must afterwards return to his lane as soon as possible in a gradual way, without forcing other users to change their direction or speed, indicating with the mandatory signals (LST Art 34,3).
4. When overtaking pedestrians, animals, two wheeled or animal drawn vehicles outside town, and the maneuver must be done using all or part of the right hand lane, as long as the conditions laid out in this regulation exist; in any case, the lateral separation must not be less than 1.5m. It is specifically prohibited to overtake if to do so would endanger or obstruct oncoming cyclists.
When overtaking other vehicles different from those of the previous paragraph, or takes place in town, the driver of the overtaking vehicle must leave a safety gap proportional to his speed and the width and characteristics of the road.
5. The driver of a two wheeled vehicle who overtakes any user outside town must do so leaving a minimum gap of 1.5m between themselves and the most salient parts of the vehicle that he overtakes.
6. Infractions of this Article are considered serious offences (LST Art 65.4.c).
