This handy illustration, courtesy of DOT via "Gridlock" Sam Schwartz, should be in the training curriculum for every delivery driver who does business in New York. Streetfilms’ Clarence Eckerson, who came across this graphic last week, says his appeals to delivery drivers stationed in bike lanes are often met by the excuse that it is not illegal to double park. When a vehicle blocks a bike lane, the law says otherwise:

No vehicle is allowed to block a bicycle lane at any time. If there is no curbside spaces on either side of the street within 100 feet of a delivery/pickup location, commercial vehicles may stand, “double parked,” next to a bicycle lane. If there is no active loading or unloading taking place standing a vehicle in such a manner can result in a violation. Please note also that this does not apply to midtown Manhattan.
