Local Vehicle Idling Regulations

A local highway authority may not enact an ordinance that prohibits or restricts an owner or operator of a vehicle from idling the vehicle’s engine, unless the ordinance is primarily educational, specifies that a person must be issued at least three warnings before a fine is imposed, has the same fine structure as a parking violation, provides for the safety of law enforcement personnel enforcing the ordinance, and specifies that the ordinance may be enforced on public property or private property that is open to the general public. Exceptions apply.
