When preparing to change lanes to your left, what must you do apart from signaling?

When preparing to change lanes to your left, it is essential to check that it is safe to do so. This involves looking in your mirrors and checking your blind spot to ensure there are no other vehicles, cyclists, or pedestrians in the lane you intend to enter. Safety is paramount in all driving maneuvers, and confirming that the lane change can be made without causing danger to yourself or others is a fundamental driving principle.

Signaling communicates your intention to other road users, but it does not replace the responsibility to verify that the maneuver can be executed safely. Checking for surrounding traffic and ensuring that the lane is clear allows you to make informed decisions while driving, thus enhancing the safety of all road users.
