What should you never do when changing lanes?

Changing lanes in an intersection is strongly discouraged because intersections are high-traffic areas where vehicles, cyclists, and pedestrians are more concentrated and moving in various directions. By attempting to change lanes at this point, you increase the risk of collisions, as other drivers may not expect or anticipate such a maneuver. Typically, the safest practice is to wait until you have cleared the intersection before changing lanes, as this allows for better visibility, control, and the opportunity to gauge the movements of other vehicles more effectively.

Changing lanes on a highway can be necessary for various reasons, such as merging, exiting, or avoiding obstacles, as long as it is done safely and with proper signaling. Signaling intentions is critical in informing other drivers of your actions, promoting safety and reducing confusion on the road. Looking in your mirrors is also an essential part of ensuring that the lane change can be made safely. These actions are vital components of safe driving, whereas changing lanes in an intersection poses unnecessary risks.
