      The term “processing device” shall not include a heater or air conditioner operated for cabin comfort.

When can a bus legally idle?

  • If the bus is being used to actively load/unload passengers. There is no violation of a bus that idles for longer than three minutes if there are passengers actively boarding during part of that idle period. This is based on the VTL definition of parking and standing.
  • A bus may not idle for any length of time at a terminal point when the temperature is over 40°F.

How is a legally authorized vehicle defined?

  • Every ambulance, police vehicle or bicycle, correction vehicle, fire vehicle, civil defense emergency vehicle, emergency ambulance service vehicle, blood delivery vehicle, county emergency medical services vehicle, environmental emergency response vehicle, sanitation patrol vehicle, cooling bus, hazardous materials emergency vehicle and ordnance disposal vehicle of the armed forces of the United States.

How long does the truck or bus have to be idling for in order to file a complaint?

  • When a truck or bus is not allowed to idle for longer than three (3) minutes, the video duration must be for at least three (3) minutes and 4 seconds, but the observation of the idling truck or bus must be three (3) minutes and one second. When a truck or bus is not allowed to idle for longer than one (1) minute, the video duration must be for at least one (1) minute and 4 seconds, but the observation of the idling truck or bus must be one (1) minute and one second.

Example: Observing a vehicle idling from 1:00:00 pm to 1:03:00 pm does not meet the requirement of more than 3 minutes as it is not longer than three minutes.

When do you use the one-minute standard?

  • When a vehicle is found idling adjacent to a public or non-public school (pre-K–12) or inside a public park (except for parking lots located within a park), then the idling limit is no longer than one (1) minute for commercial trucks.
  • A school shall include any building or structure, playground, athletic field or other property that is part of the school (15 RCNY §39–02).
  • Colleges, Universities, post graduate schools, etc. are not included in the one (1) minute rule and you would have to document more than three (3) minutes of idling.
  • Following recent appeals decisions at the Office of Administrative Trials and Hearings related to the idling of school buses adjacent to schools (DEP vs Lessel (January 26, 2023), DEP vs Selby Transportation (February 23, 2023), and DEP vs B&F Skilled, Inc. (December 21, 2023), and with the goal of reducing idling adjacent to schools, DEP is updating its best practices to clarify what is required for complaints to be pursued against idling school buses. The best practice is as follows:
    • Within 15 min of the drop off/pick up times posted by the school there will be a presumption that school buses are idling to maintain passenger comfort and would therefore be exempt from the idling law. However, this presumption is only applicable when the school bus is adjacent to a school. At any other times and/or locations, it will be the respondent’s burden to prove that the bus was idling to maintain passenger comfort. For citizens to pursue cases for school buses adjacent to schools, submissions will require inclusion of a screenshot of the drop off/pick up times from the school website or an alternative verifiable source that shows the school schedule.

Are there any situations where a respondent does not have to pay the penalty?

  • City and state vehicles, including MTA/TA buses, are subject to the idling regulations but a summons is administratively dismissed and no monetary penalty is collected.

We would appreciate it if you do observe a city or state vehicle, truck or bus idling, to send the name of the agency and the license plate number to our e-mail,, so we can follow up with that agency.

What documentation is required to submit the citizen complaint?

The following pieces of evidence are required:

EFFECTIVE 11/21/23: The video must also capture all identifying information including the license plate. The name of the company must be clearly identifiable on the truck or bus.
  • A time and date stamped still picture or screengrab clearly showing the license plate of the vehicle. If the vehicle is a truck with a separate trailer, the license plate of the truck (cab) and the name on the truck and address is also needed. We ask that you exercise caution as the license plate can be located in front of the vehicle or the rear of the truck (cab) underneath the trailer to get the license plate information.
