1. Drivers when meeting or being overtaken shall keep as close as practicable to the edge of the carriageway on the side appropriate to the direction in which they are travelling. In overtaking, a driver shall pass on the left or the right of the overtaken vehicle or animal according to the rule observed in the country concerned. These rules shall not necessarily apply in the case of tramcars, trains on roads, and certain mountain roads.
2. On the approach of any vehicle or accompanied animal, drivers shall:
(a) when meeting, leave sufficient space for the vehicle or accompanied animal coming from the opposite direction,
(b) when being overtaken, keep as close as practicable to the appropriate edge of the carriageway and not accelerate.
3. Drivers intending to overtake shall make sure that there is sufficient room and sufficient visibility ahead to permit overtaking without danger. After overtaking they shall bring their vehicles back to the right or left hand side according to the rule observed in the country concerned, but only after making sure that this will not inconvenience the vehicle, pedestrian or animal overtaken.
