Lane discipline on a high-speed expressway is a safety issue, not merely a traffic rule. Enforcement action against vehicles making sudden lane changes shows how quickly one driver’s decision can affect vehicles travelling at very different speeds. Electronic challans can create a record, but prevention also depends on signs, road markings, lighting and driver awareness.\n\nDrivers should plan a lane change early, check mirrors and blind spots, signal clearly and avoid abrupt movement near exits. Heavy vehicles and tired drivers need additional caution because braking distance rises with speed and load. Authorities should publish the location and reason for enforcement so that the campaign is understood as risk reduction rather than only a penalty drive.\n\nMumbai Talks will track crash patterns, enforcement and road design together.
