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.
No matter what kind of vehicle you drive, remember to:
- Drive at the speed limit
- Avoid sudden stops or starts
- Resist topping off the fuel tank
- Check tire pressure monthly
- Keep your vehicle well-maintained
Remember, only five consecutive minutes of idling are allowed. Your lungs will thank you for it.
