When you pull slightly into another lane to pass a cyclist, you are indeed changing lanes, even if it's just a small movement. This action requires you to check your mirrors to ensure that the lane is clear of any other vehicles, as well as to signal your intention to other road users. Signaling not only informs other drivers of your intention but also increases overall safety on the road by making your actions predictable to those around you.

Changing lanes, regardless of the distance, involves a responsibility to ensure that it is executed safely and is compliant with traffic regulations. Proper signaling before changing lanes is a critical step, as doing so alerts drivers about your maneuver, which is particularly important in busy environments where cyclists are present. This approach reduces the risk of accidents and promotes a safer driving scenario for both you and the cyclist.
