Idle Reduction Requirement - Arapahoe County
The Arapahoe County Engine Idling Policy applies to all local government vehicles and requires that drivers do not allow any engine to idle for more than one minute (or 30 seconds for off-road equipment) at any time or for more than five minutes in any one-hour period. This requirement does not apply to vehicles for which idling is necessary, including official traffic control devices or signals, traffic or other required stops, safety or health, engine testing, or at the direction of law enforcement personnel.
