On Tuesday, the District Council passed the "Specialty License Plate Amendment Act of 2016" which includes a Bicycle Awareness license plate. Previously, this had been proposed by CM Allen as the Bicycle Awareness Motor Vehicle License Plate Amendment Act Of 2016, but in committee it was combined with the "Women Veteran License Plates Establishment Amendment Act" and renamed.
The law will create a new license plate "with a bicycle awareness design that includes an image and wording to educate motorists on the 3 foot passing rule." Drivers who choose this plate will pay $45 in fees, and those fees will go to the Vision Zero Pedestrian and Bicycle Safety Fund (the old "Pedestrian and Bicycle Safety Fund").
The bill still needs to go to the Mayor, but she has already expressed support through Lucinda Barbers, the Director of the Department of Motor Vehicles, who testified in support of the bill back in September. So it looks like this will become law. This, plus the safety law and the Contributory negligence law, makes for a pretty big year, legislatively speaking.
The passing distance awareness plate seems to be a bit rare, with most states going for "Share the Road" or Missouri's "Same Road. Same Rights." Here are some examples of passing distance plates from other states.
