On a steep descent, when driving on a narrow roadway that doesn’t allow 2 vehicles to pass at the same time:

1. Both vehicles should pull into the “hard shoulders”.
2. Right of way should be given to commercial vehicles weighing more than 4 tons.
3. The vehicle driving uphill should stop.
4. Correct answer: The vehicle driving downhill should give way and stop if necessary.

WhyOn a steep narrow descent the vehicle going down gives way and stops if needed. It is harder for the one going up to stop and pull away again.
