No person exempted under the provisions of 9.36.015A shall allow an unattended vehicle motor vehicle to idle for more than 20 minutes. (CAC 9.36.010; AO No. 78-72; AO No. 2003-135, § 1, 10-21-2003) [1] Editor's note — This section was originally designated as AMC Section 9.36.020 but was renumbered due to a preexisting section with that number.

Full Breakdown
AMC 9.36.010 requires drivers leaving a vehicle unattended on a public street to stop the engine, lock the ignition, and remove the key. Section 9.36.015A carves out an exception for vehicles with remote-start ignition systems equipped with an anti-theft feature that prevents the car from being driven without the key properly inserted. AMC 9.36.017 then reins in that exception: a person relying on the remote-start exemption may not let the unattended vehicle idle for more than 20 minutes. Police, fire, ambulance, public utility, and scheduled-transit vehicles are separately exempt from the underlying engine-off rule under 9.36.015B.
Violations & Fines
Letting an unattended remote-start vehicle idle past 20 minutes violates AMC 9.36.017, enforceable as a traffic-code offense under Title 9 alongside the underlying unattended-vehicle rule in AMC 9.36.010.
