The Ames Police Department says a Governor's Traffic Safety Bureau special enforcement project last week netted 10 citations and a warning for texting while driving. Cmdr. Geoff Huff says the ban it's a good law that's proven hard to enforce. He says officers in unmarked vehicles identified texting drivers, who were then citied by other officers in marked cruisers. State law changed July 1st making texting while driving a primary offense. Before the change, drivers could only be cited for texting if they'd been pulled over for another offense.
