# Explanation: Priority in lane changes
The vehicle already travelling in the lane has priority over the one intending to change. Whoever performs the lane change must give way and wait for a safe opportunity, checking the mirrors and blind spots. This rule exists to maintain order and road safety, making the driver moving responsible for ensuring the destination lane is completely clear.
