Alternate side parking lets street sweepers clean the curb. On the days and times posted on your block's sign, cars must be moved from that side of the street. When ASP is suspended for a holiday or bad weather, you can leave your car where it is.
ASP is suspended on the legal and religious holidays listed on the City's calendar, and sometimes for snow or other emergencies. Parking meters stay in effect except on major legal holidays.
Many New Yorkers wait in the car while the sweeper passes, but it is still double parking. The safest move is to have a spot lined up before you need it.
Only if the sign on your block lists a Saturday or Sunday. Always follow the posted sign.
The easier way to handle street cleaning day
On ASP mornings, half the block is moving at once. SpotWhispr lets you see which neighbors are leaving legal spots on the other side of the street, so you can claim one and move once.
