MISSOULA - Police say Missoula's ban on texting and driving has proven difficult to enforce.
Missoula Police Capt. Chris Odlin says officers have cited "very few" drivers since the city council adopted the ban in June 2009.
It started out as a rule against both talking and texting on mobile devices while driving. But the mayor vetoed the part of the rule that banned talking on cell phones while driving.
Odlin says it has been hard for officers to determine if drivers are texting, which is prohibited, or pushing buttons on their cell phones to make a call, which is not prohibited.
Six months after the ban was adopted, three drivers had been ticketed.
