text: A study from the Harvard Center of Risk Analysis estimates that cell phone use while driving contributes to 6 percent of crashes, which equates to 636,000 crashes, 330,000 injuries, 12,000 serious injuries and 2,600 deaths each year. Due to the number of accidents that are related to conducting calls on a phone and texting while driving, some jurisdictions have made the use of calling on a phone while driving illegal. Cell phone use contributes to 6% of crashes, and drivers are at a four times greater risk of a crash.
