I Quant NY:

New York City is a complex place to drive. And when it comes to parking, there are plenty of rules and regulations to follow. It’s no wonder that sometimes people get confused and end up getting their cars ticketed or towed.
 But in all of these rules, there is one thing that very few drivers seem to know. As of late 2008, in NYC you can park in front of a sidewalk pedestrian ramp, as long as it’s not connected to a crosswalk. It’s all written up in the NYC Traffic Rules, and for more detail, take a look at this article. The local legislation making these parking spots legal was proposed by Council Member Gentile, and adopted by the Department of Transportation before it ever made it for a vote. Though few people seem to know about the change.
