Alternate Side Parking (ASP)

Alternate side parking (ASP) is NYC's street cleaning program that requires vehicles to be moved from one side of the street during designated hours so mechanical sweepers can clean the curb lane. ASP rules are posted on signs throughout the city, typically with 90-minute windows on specific days (e.g., "No Parking 8:30–10 AM Mon & Thu").

ASP is one of the most complex and frequently misunderstood parking regulations in NYC. Rules vary block by block, with different days and times on opposite sides of the same street. ASP is suspended on 34 official holidays (including religious holidays from multiple faiths) and during declared weather emergencies — but the suspension calendar itself is a source of confusion. NYC's @ABORINGDYSTOPIA and @NYCparking social media accounts post daily ASP updates.

For fleet operators parking vehicles on city streets, ASP violations (code 21, $65 fine) are among the most common and most preventable tickets. The key is knowing the ASP schedule for every location where your vehicles are parked. Clear Plates flags alternate side violations and helps you identify which parking locations are generating repeat ASP tickets so you can find better options or establish move protocols.
