As accidents involving drivers using phones mount across the U.S., many states have started to outlaw or restrict phones while driving. They found that 68 percent of respondents \"would need a lot of convincing\" to believe that texting while driving is dangerous. Females were more likely to use their smartphones while driving than males, the study found. As of July 2018, 47 states ban texting while driving and 16 ban using a handheld device — whether for talking or texting — while driving. The scientists found that drivers who'd been driving for a long time were less likely to call or text while driving than newer drivers.
