A study released at a Traffic Safety conference in Kansas City questions whether state bans on texting while driving really make roads any safer.

The study by an arm of the Insurance Institute for Highway Safety looked at several states with texting bans and says the bans are not improving highway safety. In fact the study shows texting-caused crashes are increasing.

The study’s presenter at the conference tells the Kansas City Star that the laws are not stopping texting but they might be forcing drivers to do it in a more dangerous way.
