Difficulty: EasyMountain Driving and Steep Grades

When two vehicles meet on a narrow mountain road where only one vehicle can pass safely and neither can pull over, which driver is required to yield the right-of-way?

  1. The vehicle facing downhill, by backing up until the vehicle traveling uphill can pass safelyAnswer
  2. B
    The vehicle facing uphill, because ascending vehicles can stop faster and reverse downhill with greater ease
  3. C
    The faster vehicle, which must immediately apply heavy braking to allow the slower vehicle to proceed
  4. D
    The lighter vehicle, requiring all passenger cars to yield right-of-way to heavier trucks regardless of incline direction

Answer

The vehicle facing downhill must yield the right-of-way by backing up until the vehicle traveling uphill can pass safely.
When two vehicles meet on a steep, narrow mountain road where they cannot pass, the vehicle traveling downhill must back up until the vehicle going uphill can safely pass. This is because the driver going downhill has much better control of their vehicle when backing up.

Step-by-Step Solution

1
Identify the primary hazard in the scenario
Two vehicles are on a narrow steep grade with insufficient space to pass safely.
Determining space constraints establishes the need to apply narrow grade right-of-way rules.
2
Apply standard DMV mountain driving right-of-way rules
The vehicle traveling uphill has the right-of-way.
Backing down a mountain grade is extremely dangerous; the downhill vehicle has far greater control when backing up uphill.
