In terms of safety, how can reaching for a device while driving be categorized?

Reaching for a device while driving primarily qualifies as a manual distraction because it involves the physical act of using your hands to manipulate something other than the steering wheel. This action diverts your attention from the crucial task of driving, as it requires you to take at least one hand off the wheel, which can significantly reduce your control of the vehicle.

While it may also lead to cognitive distraction (as your mind may start thinking about the task of using the device) and visual distraction (if you are looking at the device instead of the road), the key aspect in categorizing the act of reaching for a device itself is the manual aspect. Engaging in actions that require manual involvement can prevent a driver from properly responding to road conditions or obstacles, thus posing a significant safety risk.
