Respuesta :
Answer:going uphill; downhill.
Explanation:A steep road is a road has a that 45-degree pitch and both mean that a run descends one vertical foot for each horizontal foot. For a one way mountainous road,if two vehicles meet at a steep point, the enabling traffic law states that the vehicle going uphill must back up for the one going downhill to pass through. This is to prevent any form of accident,as the vehicle descending will be coming with a very high velocity than the one trying to go uphill.
Answer:
On a one lane mountain road when two vehicles meet on a steep road where neither can pass, the vehicle facing downhill must back up until the vehicle going uphill can pass.
Explanation:
When two vehicles meet on a steep slope/road where they neither can pass, the vehicle facing downhill must yield backing up until the vehicle going uphill can pass. This is because the vehicle facing downhill has the best/greater amount of control of the vehicle when backing up.
