Heavy Duty Vehicle Idling Laws

New York State Environmental Conservation Law (ECL) prohibits heavy duty vehicles, including diesel trucks and buses, from idling for more than five minutes at a time.

EXCEPTIONS ARE WHEN YOUR VEHICLE IS:

• Stuck in traffic
• Idling for maintenance purposes
• Powering an auxiliary function or apparatus, such as a concrete tumbler
• Involved in an emergency situation
• A diesel fueled truck operating in an ambient air temperature below 25°F for more than 2 hours

Less idling time is good for the environment because it reduces air pollution, noise and fuel use. It also saves money for diesel operators and consumers and contributes to a cleaner atmosphere.

The diesel idling regulation is found in Title 6 NYCRR, Subpart 217-3 and will be enforced by DEC Conservation Officers. You may be fined from $500 to $18,000 in the case of a first violation.
