Which type of distraction involves not being fully aware because of thinking about other things?

Cognitive distraction is the type that involves a lack of full awareness due to the mind being occupied with other thoughts. When a driver's attention is diverted because they are thinking about personal issues, planning their day, or recalling past events, their cognitive focus on driving diminishes. This can lead to slower reaction times and an inability to process important visual and auditory information from the driving environment.

In contrast, visual distractions draw attention away from the road using sight, such as looking at a phone or adjusting the radio. Auditory distractions involve sounds that capture attention, like loud music or conversations, which can divert focus but do not occupy cognitive processing in the same way. Biomechanical distractions relate to physical movements not directly tied to driving, such as reaching for items in the vehicle.
