More than a quarter of all car crashes in America are likely caused by cell phone use, a study by the Nation Safety Council has shown. According to the NSC, the estimate for crashes caused by texting rose to at least 6% in 2017. Additionally, 21% of crashes in 2017 were related to the use of handheld or hands-free phones. The council estimates that talking on the phone led to 1.2 million wrecks in 2017, while texting was involved in at least 341,000 more. The NSC found that 9% of drivers at any time during daylight hours were talking on cell phones, and that drivers talking on the phone while behind the wheel were four times as likely to crash as drivers who were not using their phones.
