Idle Free Fact Sheet

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
