JJ Keller Entry Level Driver Training for CDL (Commercial Driver’s License) Practice Test

Drifting out of the lane is a clear indication that a driver may be distracted. This behavior suggests a lack of attention to the road and surrounding traffic conditions, which can be caused by various distractions such as phone use, engaging in conversation, or being preoccupied with something other than driving. When a driver fails to maintain their position within the designated lane, it signals a potential impairment in their focus, making it a critical observation for others on the road.

In contrast, using turn signals consistently, maintaining a constant speed, and frequent lane changes are typically indicative of a driver who is attentive to their driving environment. Consistent use of turn signals shows awareness of the need to communicate intentions to other drivers. Maintaining a steady speed reflects good control and awareness of traffic conditions, while frequent lane changes might suggest assertiveness or adaptability to the flow of traffic, but not necessarily distraction. Engaging in these behaviors does not typically signify a lack of attention, which reinforces why drifting out of the lane is a more telling sign of distraction.
