Idle Reduction Requirement
The owner or operator of a diesel-powered vehicle must limit the length of time their vehicle remains idle. The limit is based on the outside temperature, as follows: above 32 degrees Fahrenheit, 5-minute limit in any 60-minute period; between 32 and -10 degrees Fahrenheit, 15 minute limit in any 60-minute period; below -10 degrees Fahrenheit, no limit. Certain vehicles are exempt from the regulation, including vehicles in traffic, emergency vehicles, vehicles providing power take-off for refrigeration or lift gate pumps, vehicles idling for required maintenance or diagnostic purposes, and vehicles supplying heat or air conditioning for passenger comfort during transportation.
