Why is it crucial to avoid sudden lane changes?

Avoiding sudden lane changes is crucial because they can create confusion among other drivers, significantly increasing the risk of collisions. When a driver unexpectedly swerves into a different lane without signaling or checking their mirrors, other road users may not have enough time to react. This unpredictability can lead to rear-end collisions, side-swipe accidents, or even more severe crashes, especially if other drivers are not expecting such a maneuver. Clear and predictable driving behavior, including using turn signals and checking blind spots, is critical in maintaining safety for everyone on the road.
