Quick Tip
Detached trailers cannot be parked on NYC streets. If the trailer was attached to a vehicle at the time of the ticket, provide photographic evidence showing it was connected.
When this ticket gets issued
Code 66 is issued for parking a detached trailer on a public street. NYC prohibits trailers from being separated from their tractor or tow vehicle and left on the roadway. The ticket is common when a construction or delivery operation drops a trailer to swap equipment, or when a long haul driver leaves a trailer overnight while the cab goes to a garage. It also appears when agents misidentify an attached-but-slack trailer connection as detached. The charge reflects the city's concern about street storage of large trailers that obstruct traffic and block curb access.
How to fight code 66
Trailer was attached to a vehicle at the time of the ticket
Provide photographs showing the trailer connected to its tractor or tow vehicle at the ticket minute. Driver and yard-worker statements attesting to continuous connection help. For code 66, a single clear photo of the attached fifth wheel or hitch typically defeats the detached-trailer allegation.
Evidence to bring: written_account
Vehicle was not at this location at the time
Submit yard logs, gate records, or GPS data showing the trailer was inside a lot or hooked to a tractor on a different street at the ticket minute. Code 66 tickets cite specific street locations; telematics or yard records contradicting that location generally prevail at hearing.

Wrong plate number on the ticket
Trailer plates and tractor plates are separate. Verify the plate on the summons matches your trailer's registration, not the tractor. A mismatch — especially confusing a trailer plate with a tractor plate — is a clear basis for dismissing code 66.

Frequently Asked Questions
Does code 66 apply even during a brief swap at a loading dock?
Technically yes, though brief mechanical swaps with supporting operations paperwork can be explained as continuous commercial activity. The safer practice is to complete swaps off-street inside a yard. If a street swap is unavoidable, document times precisely so any ticket can be challenged on location and timing.
What counts as attached for code 66 purposes?
A trailer is attached when it is mechanically connected via fifth wheel, pintle hook, or other tow coupling to a capable power unit. Slack air lines or a tractor parked alongside without connection do not count. Agents look for a clear mechanical link. A photo of the coupling is the most effective evidence.
Can we park a trailer on the street overnight with a note on the windshield?
No. Notes do not create a legal exception. Detached trailers on NYC streets are citable at any hour. Overnight storage should be in a yard or gated lot. Fleets that regularly drop trailers on-street should identify off-street staging options to eliminate ongoing code 66 exposure.
What this means for commercial fleets
Code 66 mostly affects trucking, construction, and wholesale-market fleets that operate tractor-trailer equipment. At 65 dollars per ticket, individual fines are moderate, but repeat hits suggest a yard-capacity or operational problem. The preventive fix is almost always off-street staging for detached trailers; on-street drops should be limited to active, brief swaps with photographic documentation. For last-mile delivery fleets using only box trucks or vans, code 66 should not appear — if it does, expect a plate-type error on the summons.
