Final answer:
Additional right lanes on mountain roads for slower-moving vehicles improve traffic flow and safety by allowing faster traffic to pass. They prevent abrupt slowing down of fast vehicles, reducing accident risks and maintaining road tranquility.
Step-by-step explanation:
Additional right lanes on mountain roads are often created for slower-moving vehicles to allow faster traffic to pass safely. This is a common feature designed to improve traffic flow and increase safety on roads where vehicles might be traveling at different speeds, especially on steep inclines where heavier vehicles, such as trucks, may need to reduce speed.
These lanes are particularly important because they help to prevent situations where faster vehicles have to slow down abruptly, which can reduce the risk of accidents.
For example, on an uphill road in mountainous terrain, a truck might move to the additional right lane, allowing passenger cars to continue at a steadier and faster pace. Conversely, scenarios such as the one involving Peter and the slow driver in front of him point out the utility of having a system in place to manage different speeds on roadways to avoid potential road rage incidents or accidents.
Similarly, ensuring the safety of non-vehicular trail users, such as hikers and cyclists, requires appropriate planning and infrastructure to prevent conflicts and maintain the peace of natural settings.
