License-plate violations go unticketed for months

"Residents who ignore the District's license-plate registration laws typically go unticketed for as long as two months, even though they can be ticketed every night, city officials said.
D.C. law requires people who live in the city for more than 30 days to register their cars with the D.C. Department of Motor Vehicles (DMV) or face a $100 ticket every day." By Amy Doolittle
