La Mesa police and county probation officers posted themselves at the courthouse parking lot entries about 3 p.m. to screen drivers going in and out, police Lt. Dan Willis said.
Willis said they timed the checkpoint for the start of a court-ordered class for those convicted of drunken driving. Over the next two hours, officers screened 171 drivers and found 13, most of them from around East County, with no valid license.
The sting is one of many operations targeting drunken drivers funded by a grant from the California Office of Traffic Safety through the National Highway Traffic Safety Administration.
