Ralph Nader, former presidential candidate, Library Renaissance supporter and typewriter lover, has taken up a new cause: Getting D.C. to fix an intersection marred by illegal left turns.

WTOP obtained the letter Nader sent to Mayor Vincent Gray and Metropolitan Police Department Chief Cathy Lanier earlier this week in regards to the intersection of Florida and Connecticut Avenues NW.

Nader writes that he noticed 32 vehicles making the illegal turns on two days in June and July as he observed the intersection during morning and afternoon rush hours.

“Many of the drivers making the illegal turns were, it seemed, not aware that it was prohibited to do so. They were new either to the city or to the intersection. Many cars slowed in the middle of the intersection with their turn signals on, often times with cars behind them,” writes Nader in a letter obtained by WTOP.

“When there was heavy traffic and cars got backed up on Florida Avenue, many drivers decided at the last moment that it was easier to make a sharp left turn onto Connecticut Avenue.”

Nader calls for signage and more enforcement by the MPD in the letter. The District Department of Transportation is already making improvements, according to WTOP, and the MPD is “evaluating the concerns” raised by Nader.

If you need something done in this city, ask Nader to pull out his typewriter.
