unsafe lane change
Dangerous lateral maneuver
An unsafe lane change is switching lanes in a way that endangers other drivers—without signaling, cutting off nearby vehicles, or failing to check blind spots.
The term appears in traffic law and insurance claims: He was cited for an unsafe lane change after sideswiping the other car.
It's a common cause of accidents and traffic stops.
