A climbing lane is a lane on a road or highway designed to help slower vehicles, such as trucks, move uphill more easily. This lane is typically added on steep roads or inclines where vehicles may struggle to maintain speed. It provides extra space for slower-moving traffic to allow faster vehicles to pass without causing delays or congestion. The climbing lane helps improve safety and traffic flow, especially on roads with significant elevation changes.
