Raleigh, N.C. — Leaders of the North Carolina State Highway Patrol are discussing a policy that would require troopers to provide supervisors with copies of their cell phone bills.

The goal, they say, is to make sure troopers aren't spending too much time talking and texting on their personal phones while on the job.

The policy is part of ethics reforms coming after a series of embarrassing episodes involving troopers' misconduct.

In one case, the Highway Patrol's longtime spokesman resigned amid an internal investigation in which he sent text messages to his secretary.
