A Bethesda woman escaped her speed camera ticket after she uncovered maintenance problems with Gaithersburg’s cameras.

Peggy Lucero was nabbed by a speed camera in a 30-mile-per-hour zone on Route 355 in Gaithersburg. Instead of paying the $40 fee like most Maryland motorists, Lucero dug up records on camera maintenance and asked the State Highway Administration to validate the area’s speed limit.
