What does the term “failure to maintain lane” mean?

The term "failure to maintain lane" specifically refers to a driver's inability to stay within the boundaries of their designated lane while operating a vehicle. This can occur due to various reasons, such as improper steering, intoxication, or distraction, and it poses a significant safety risk on the road, as it can lead to collisions with other vehicles or objects.

Maintaining lane discipline is crucial for road safety because it ensures that all drivers accurately gauge their position on the road and allows for smoother and safer traffic flow. This definition aligns perfectly with the essence of the term, which directly addresses the behavior of not adhering to the rules of the roadway regarding lane use.

While changing lanes without signaling, driving while distracted, and driving over the speed limit are all dangerous driving behaviors, they do not specifically encompass the idea of "failure to maintain lane." Those behaviors address different aspects of driving conduct that may lead to unsafe situations but do not directly relate to the act of remaining within a lane.
