Violators may be fined up to $1000 per day and may face possible criminal charges.
The California Air Resources Board is recommending truckers that haul in the state adopt anti-idling technologies like Battery-Powered Auxiliary Power Units (APUs); Fuel-Fired Heaters (certain restrictions apply); or use truckstop infrastructure that provides heating, cooling, electricity, and/or other services at various locations throughout California.
However, as per further restrictions on diesel-powered APUs, they must meet additional emissions standards on new 2007 trucks and cannot be operated for more than five minutes within 100 ft of a residential area.
Idling is acceptable only when the truck is stuck in traffic or immobile due to adverse weather; is being inspected or serviced, or is operating a power take-off device.
