NJ law is hands-free, and our town had that law years before NJ did. Doesn't stop them, especially the texting.
In MN any texting or emailing, etc. is a $300 fine if caught. Teens under 21 that get caught texting lose their license until age 21. That's not to say that people don't do this but at least they can get pulled over for it. The young kids are pretty good about NOT texting and driving because they don't want to lose their license-it's the 21-30 year olds that are the problem.
