Question

Difficulty: MediumMountain Driving and Steep Grades

Two drivers approach each other on a steep, narrow mountain road where passing is impossible due to space constraints. According to standard right-of-way rules, which driver must yield by backing up?

  1. The driver traveling downhill, because the vehicle moving downhill has greater control when backing up.Answer
  2. B
    The driver traveling uphill, because maintaining momentum is less critical than avoiding downhill collisions.
  3. C
    The lighter vehicle, regardless of whether it is heading uphill or downhill.
  4. D
    The vehicle moving at the higher speed, regardless of direction of travel.

Answer

The driver traveling downhill must yield the right-of-way by backing up until the vehicle heading uphill has room to pass.
On a narrow mountain road where two vehicles cannot pass, the driver traveling downhill is required by law to yield the right-of-way by backing up until the uphill vehicle can pass. The downhill driver has greater control over their vehicle while backing down compared to a driver attempting to back up a steep incline.

Step-by-Step Solution

1
Identify the traffic scenario constraints
Two vehicles meet on a steep, narrow mountain grade where space prevents passing without yielding.
Understanding mountain driving spatial constraints.
2
Apply standard DMV mountain right-of-way rules
The driver descending the slope must yield and back up.
Reversing downhill allows for significantly better vehicle control than backing uphill against gravity.
