Effective July 1, 2009, a person under the age of 18 may not operate a motor vehicle while using a cell phone unless calling 911. So, parents let the kids know that talking on a cell phone while driving a car when you are under 18 is illegal. We all know that underage drivers are more prone to being involved in car crashes then adult drivers. Now, studies show that underage drivers who talk on a cell phone are at an even greater risk to be involved in a car crash. Remind the kids to stay off the cell phone – no email, no texting, and talking on the phone – while driving.
