If a truck and a dual-purpose vehicle arrive at the same time at a very narrow section of road where the right-of-way is not indicated by signs, which vehicle must go first?

Correct answer: The truck.

If they arrive at the same time, it is unclear who entered first, so the list of vehicle types applies. The adaptable dual-purpose vehicle, which can carry people and cargo, is not on that list. In that case, the vehicle that would have to back up farther goes first. If the distance is the same, the one with the greater width, length, or maximum authorized mass goes first, which is the truck. Being smaller does not give the dual-purpose vehicle the right-of-way.
