What does the term "unsafe lane change" imply?

The term "unsafe lane change" specifically refers to the action of changing lanes without adequately checking mirrors and blind spots. This practice is dangerous because it significantly increases the risk of collisions and accidents. By not observing the surrounding environment, a driver may not be aware of vehicles that are in adjacent lanes or traveling in the same direction, which can lead to dangerous situations, such as side swipes or loss of control over the vehicle.

Utilizing turn signals is an important part of changing lanes, but if a driver neglects to check for other vehicles before making the maneuver, the act remains unsafe regardless of signaling. Similarly, changing lanes in heavy traffic or when the road is clear may have different implications, but it is the lack of proper checks that fundamentally defines an unsafe lane change. Ensuring visibility and assessing the area around the vehicle are crucial steps to safely executing a lane change.
