Before changing lanes, a driver must signal their intent and check mirrors to ensure that the lane is clear and safe to move into. This precaution helps prevent collisions with vehicles in adjacent lanes and assists in maintaining a smooth traffic flow. Signaling provides a warning to other drivers of the change, thereby minimizing sudden interruptions and potential accidents. It is a necessary practice to alert others on the road of driving intentions, as required by law.
