Which of the following is a common cause of accidents?

Distracted driving is a significant cause of accidents as it compromises the driver's ability to focus on the road and react to potential hazards. When a driver's attention is diverted—whether by mobile devices, passengers, or other distractions—the likelihood of making critical mistakes increases dramatically. These mistakes can lead to slower reaction times, not noticing traffic signals, or failing to maintain a safe distance from other vehicles, all of which contribute to the risk of collision.

In contrast, while other factors such as driving below the speed limit and using a GPS device can present risks, they do not intrinsically lead to accidents in the same way that distraction does. Driving alone generally provides fewer distractions, and when done properly, it typically doesn't contribute as much to accident risk as the cognitive overload from distracted driving.
