If you park in a red-top meter space and you're not disabled, D.C. officials will give you a lecture on the law and a warning this month, and a ticket next month.

The special meters, marked with a red top, are reserved for people with disabilities and allow for double the parking time that normal meters in the same area do.

The district installed about 400 of the meters in January.

Starting this month, officials with the District Department of Transportation will be stationed at the meters to  explain the red-top rules. The District Department of Public Works will give warnings to people who park in the spaces without a proper disability license tag or placard. In March officials will start ticketing or towing those illegally parked in the spaces.
