What is one of the main causes of driver distractions?

Answer: C — Use of mobile devices while driving

Using mobile devices while driving is recognized as one of the main causes of driver distractions because it diverts the driver’s attention from the road. Engaging with a mobile device can require visual, manual, and cognitive resources, leading to a significant increase in the likelihood of accidents. Actions such as texting, browsing, or even talking on the phone can impair a driver's ability to react to changing traffic conditions or unexpected hazards, ultimately compromising road safety. While listening to music, adjusting the radio, or focusing on road signs can also contribute to distractions, they typically don't pose the same level of danger as mobile device usage. Music can be automated and does not require the same level of concentration, and road signs are essential for navigation and safety. In contrast, mobile device interactions often lead to divided attention, making them particularly hazardous.
