In narrow passages where vehicles cannot cross without difficulty, the driver who arrives first at the narrowing point has priority. As the light vehicle is already positioned and arrived first at the narrow passage, the driver of the heavy vehicle approaching from the opposite direction must give way, waiting for the light vehicle to complete the crossing. The other options are incorrect because the heavy vehicle driver should not advance, as this would impede the passage of the light vehicle that has already started crossing. The option to reverse also does not directly apply as a first measure, as it is sufficient for the heavy vehicle to stop and give way before entering the narrow section.
