For D.C. car owners sick of gridlock caused by suburban commuters, nothing would improve life like having all those Maryland and Virginia cars disappear. But thanks to a computer glitch at the city’s Department of Motor Vehicles (DMV), it was thousands of District drivers who were temporarily nonpersons last month. According to DMV Deputy Director Henry Lightfoot, two or three drivers a day were calling to say they’d been pulled over and informed that their recently issued D.C. tags weren’t registered. Staffer Barbara Gibbs says an overtaxed computer system had somehow misplaced information on plates beginning with AL or AM. And Lightfoot adds that information on plates that had been lost or duplicated was also inaccessible. Don’t go ripping up your parking tickets just yet: Gibbs says that after a week of overtime by the department’s tech staff, all the tags are back on the record. The aged computer system, though, won’t be replaced until next spring.
