"Texting bans haven't reduced crashes at all. In a perverse twist, crashes increased in 3 of the 4 states we studied after bans were enacted. It's an indication that texting band might even increase the risk of texting for drivers who continue to do so despite the laws," commented IIHS and HLDI president Adrian Lund.

Lund said that these findings "call into question the way policymakers are trying to address the problem of distracted driving crashes."
