Two vehicles meet on a narrow mountain highway with turnouts and a grade of at least 6%. They cannot pass. A turnout is readily available behind the downhill vehicle, and it is not more practical for the uphill vehicle to return. Who must yield?
Two vehicles meet on a narrow mountain road that rises to the right. The blue vehicle faces uphill, the silver vehicle downhill, and a turnout lies behind the downhill vehicle.
Correct answer: The downhill vehicle must yield to the uphill vehicle.
Why
On a narrow mountain highway with turnouts and a grade of at least 6%, the downhill driver yields to the uphill driver unless it is more practical for the uphill driver to return to a turnout. Here the downhill driver should carefully return to the available turnout when safe and let the other vehicle pass.
