When vehicles meet on a steep narrow road not wide enough two vehicles which vehicle must yield has the right of way?

In situations where two vehicles meet on a steep, narrow road that is not wide enough for both to pass, the vehicle facing downhill generally has the right of way. This is because it is easier for the vehicle going uphill to back up to a wider spot, while the downhill vehicle has the momentum and control. However, local traffic laws should always be consulted, as regulations may vary by region.
