The number of fatal car accidents nationwide has risen 18% over the past five years. This statistic coincides with a marked increased in smartphone use over the same time period, and with an accompanying rise in the number of drivers who text or browse the Internet on their phones while on the road. A nationwide study found that fully 60% of fatal traffic accidents involved a driver who was texting or browsing at the time of the incident. Laws exist in many states that outlaw smartphone use while driving. However, to prevent a further rise in smartphone-related accidents, penalties should be strengthened to further deter drivers from partaking in such dangerous activities.
Which of the following, if true, most strongly supports the claim that penalties should be increased for drivers who are caught texting or browsing the Internet?
