Chapter II
RULES OF THE ROAD
ARTICLE 19
Level-crossings
Road-users shall exercise extra care in approaching and traversing level-crossings. 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 level-crossing 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;
(e) No road-user shall linger while traversing a level crossing; if a vehicle is compelled to stop, its driver shall endeavour to move it off the track, and, if he is unable to do so, immediately do everything he can to ensure that the drivers of rail-borne vehicles are warned of the danger in time.
