Addressing an Idling Vehicle

Education is a vital part of being an idle-free city. If you are able to talk to the owner of an idling vehicle, please ask them to turn off their vehicle until they are ready to drive.

  • Here is a sample conversation you can use to kindly ask the operator of an idling vehicle to “turn your key, be idle free.”
  • To request “turn your key, be idle free” window decals, please email Your Key Be Idle Free signage example

Report an Idling Vehicle

Salt Lake City Compliance Officers are available to educate and enforce the Idle Free Ordinance. Report an idling vehicle online, or call (801) 535-6628 and report in real time.

Idle Free Utah

Unnecessary vehicle idling affects lungs all across Utah. Please contact Utah Clean Cities if you are interested in helping your community — outside of Salt Lake City limits — be idle free.
