Which of the following is a potential consequence of using a cellphone while driving?

Using a cellphone while driving significantly increases the risk of collisions. This is primarily because the act of using a cellphone distracts the driver from focusing on the road and their surroundings. Distractions can affect a driver's ability to react quickly to changing situations, such as an unexpected stop by the vehicle in front, pedestrians crossing the street, or other motorists' behavior.

Research shows that engaging in conversations, whether through texting or calls, can lead to cognitive distractions, which impair decision-making and situational awareness. Additionally, visual distractions occur when the driver looks at their phone instead of the road, increasing the likelihood of an accident. Thus, the correct answer highlights the critical danger that cellphone use poses while driving and underscores the importance of remaining fully attentive to driving tasks.
