Which of the following is a common hazard when driving?

Distractions from passengers or devices represent a significant hazard when driving because they divert the driver's attention away from the road and critical driving tasks. Being distracted can result in slower reaction times, an inability to properly assess road conditions, and a greater likelihood of making mistakes, such as failing to notice pedestrians, cyclists, or changes in traffic signals.

In contrast, staying within the speed limit, following traffic rules strictly, and adjusting mirrors before starting the car are all practices that promote safer driving. They are proactive steps that enhance situational awareness and ensure that the driver operates the vehicle more effectively. Therefore, those actions are not common hazards, as they contribute to safer driving conditions.
