Outside built-up areas, in order to facilitate overtaking, drivers of vehicles or combinations of vehicles of more than 3,500 kg permissible maximum mass, or of more than 10 m overall length, shall, except when they are overtaking 15 r preparing to overtake, keep at such distance from power-driven vehicles ahead of them that other vehicles overtaking them can without danger move into the space in front of the overtaken vehicle. However, this provision shall not apply in very tedious traffic or in circumstances where overtaking is prohibited. In addition (a) The competent authorities may exempt certain conveys of vehicles from this provision, or may similarly make it inapplicable on roads where two lanes are allotted to traffic in the direction concerned (b) Contracting Partie s and subdivisions thereof may prescribe different figures from those given in this paragraph with respect to the vehicle characteristics concerned.

The warning given by the direction-indicator or direction-indicators shall continue to be given throughout the manoeuvre and shall cease as soon as the manoeuvre is loved. ARTICLE 15 supererogatory regulations relating to regular public- bring service vehicles It is recommended that domestic legislation should provide that in built-up areas, in order to facilitate the movement of regular public- exile service vehicles, the drivers of other vehicles shall, subject to the provisions of Article 17, paragraph 1, of this Convention, slow down and if necessary stop in order to allow the public-transport vehicles to perform the manoeuvre required for moving off from stops marked as such. The provisions thus laid down by Contracting Parties or subdivisions thereof shall in no way affect the duty incumbent on drivers of public-transport vehicles to take, after having given warning by means of their direction-i ndicators of their intention to move off, the precautions necessary to avoid any risk of accident. 16 ARTICLE 16 Change of direction 1.

A driver who has entered an intersection where traffic is regulated by traffic light signals may clear the intersection without waiting for the way to be opened in the direction in which he wishes to proceed, provided that this does not impede the progress of other road-users moving in the open direction. 7. Drivers of vehicles not moving on r unway shall give way to rail-borne vehicles. ARTICLE 19 Level-crossings Road-users shall exercise extra care in approaching and traversing levelcrossings. In particular (a)Every driver of a vehicle shall drive at a moderate speed (b) Without prejudice to the obligation to obey an instruction to stop given by a light signal or a sound signal, no road-user shall enter a levelcrossing at which the gates or half-gates are across the road or in process of being placed across the road, or at which the half-gates are in process of being raised (c) If a level-crossing is not equipped with gates, half-gates or light signals, no road-user shall enter it without making sure that no rail-borne vehicle is approaching (d) No driver shall enter a level-crossing without first ascertaining that he may not be obliged to stop on it 18 (e) vehicle is and, if he drivers ofNo road-user shall linger while traversing a level crossing if a compelled to stop, its driver shall endeavour to move it off the t rack, is unable to do so, immediately do everything he can to ensure that the rail-borne vehicles are warned of the danger in time. ARTICLE 20 Rules applicable to pedestrians 1.
