The National Safety Council has just released a report showing that cell phone use was involved in 27% of all U.S. car crashes in 2013, (the most recent year fully studied), and the third straight year that percentage has increased.
Texting while driving is the biggest culprit in the uptick as 6% of all crashes involve texting according to the report. The Council and other safety organizations estimate that texting while driving increases your chances of getting into an accident by eight times the non-texting rate. But the study also says that even hands free cell phone use is a problem and increases your chances of getting into an accident by four times.
And the Council still believes the role of cell phones in crashes is still underreported in the official federal data.
