Under Title 21, which of the following is a common form of distracted driving?

Texting or using a mobile device is recognized as a common form of distracted driving due to its significant impact on a driver’s attention. Engaging in these activities diverts not only the visual attention from the road but also the cognitive resources, as the driver is mentally focused on the device rather than their surroundings. This increases the risk of accidents substantially, making it a priority in discussions about road safety and legal guidelines.

While other activities, such as changing the radio or talking to a passenger, can also be distractions, texting involves a higher level of engagement with a device that has been widely studied and specifically pointed out as a critical issue in promoting traffic safety. Laws often focus on mobile device usage given the prevalence of smartphone use and the corresponding rise in distracted driving incidents, which is why it stands out as an example in the context of distraction. Adjusting mirrors, although also a form of distraction, generally takes less cognitive load and is often performed as a routine task rather than as an active engagement that takes the driver's focus from driving.
