What is an example of a non-driving activity distraction?

Using a navigation system is an example of a non-driving activity distraction because it requires cognitive focus and visual attention that diverts from the primary task of driving. Engaging with a navigation system often involves reading maps, entering destinations, and interpreting directions, all of which can take a driver's attention away from the road and increase the risk of an accident. While navigation aids can be helpful for route planning, they can also lead to a momentary lapse in focus that is unrelated to the act of controlling the vehicle itself.

On the other hand, adjusting mirrors, checking the rearview mirror, and maintaining a firm grip on the wheel are all related to the driving activity. These actions are necessary for safely operating a vehicle, ensuring visibility, and maintaining control, thereby promoting safe driving practices rather than detracting from them.
