Warning: don’t drink and bike.

A recent ruling by the D.C. Court of Appeals means that District law allows for the arrest of  intoxicated bicyclists.

Last week the court upheld the conviction of a man who was arrested in 2007 for being under the influence of alcohol while riding a bike, which he argued did not qualify as a vehicle under the D.C. Traffic Act of 1925.

However the judge in the case pointed to the law’s language, defining a vehicle as “any appliance moved over a highway on wheels or traction tread, including street cars, draft animals, and beasts of burden,” according to the blog of the Legal Times.

While DUI cases involving bikes are not as common as those involving motor vehicles, The Washington Post reports that in 2008 nearly a fourth of the bicyclists who died in road accidents with alcohol in their bloodstreams had blood-alcohol levels of .08 or higher.
