Last winter, the Council smacked down the prospect of having more “special signs” (read: billboards) permitted in the District, hewing to D.C.’s longstanding prohibition on the unsightly advertising. Even Mayor Adrian Fenty, whose attorney general worked to break the moratorium, proudly presided over their removal (after a D.C. agency embarassingly plastered an ad on one display).

Now, with the need to get the word out about the tax amnesty, it seems the District has found its way around that pesky prohibition: Putting a gigantic ad on a truck that sits in downtown traffic. This is gridlock at work for you!
