State officials are stepping up enforcement this week of the ban on texting while driving. It’s illegal even while stopped in traffic.
E-mailing or accessing the Web on a wireless device while driving is also illegal.
More than 100 law enforcement departments around the state were increasing patrols today to look for violators.
The state Department of Public Safety says the law specifically states that no person may operate a motor vehicle while using a wireless communications device to compose, read or send an electronic message, when the vehicle is in motion or a part of traffic.
The law does not apply to devices that are permanently affixed to the vehicle or global positioning systems or navigation systems.
All cell phone use for teen drivers with a provisional license has been prohibited by a law in effect since 2006.
Correction: An earlier version of this story incorrectly stated that the ban took effect this week; it dates to 2005.
