How much more likely is a motorist using a handheld device to have a serious accident that causes injury, according to a Monash University study?

Answer: C — 4 times

The finding that a motorist using a handheld device is four times more likely to have a serious accident that causes injury is derived from comprehensive research conducted by Monash University. This comparison highlights the significant risks associated with distracted driving, particularly from the use of handheld devices. Studies in this field often focus on the cognitive distractions that lead to decreased attention on the road, slower reaction times, and impaired decision-making processes. The statistic emphasizes the escalation of danger while engaging with phones or similar devices while driving, reinforcing the importance of promoting safer driving behaviors and advocating for the use of hands-free technology when necessary.
