When two vehicles meet on a hill with one lane, who has the right of way?

The correct answer is that the vehicle that is going uphill has the right of way when two vehicles meet on a hill with a single lane. This rule is based on the principle that a vehicle going uphill has a better chance of maintaining traction and control compared to a vehicle going downhill, which may have to rely more on brakes. If both vehicles were to attempt to pass each other, the downhill vehicle could potentially lose control and cause a dangerous situation.

While larger vehicles might generally have some advantages in specific circumstances, the standard regulation regarding right of way on hills prioritizes the uphill vehicle to promote safety and facilitate smoother traffic patterns. The vehicle on flat ground does not have any inherent advantage over either of the uphill or downhill vehicles. Hence, acknowledging the safety and control considerations, giving right of way to the vehicle going uphill is the most sensible rule in this scenario.
