The Park City Police Department last week received at least three complaints about idling vehicles.
City Hall prohibits idling for more than three minutes unless it is cold or hot outside.
The cases included:
Public police logs did not provide details about the cases. It is not known whether the temperatures at the times of the reports were cold enough that idling for longer than three minutes would have been allowed by the law. The temperature benchmark is 32 degrees Fahrenheit.
Park City leaders in 2010 adopted the prohibition on idling for more than three minutes as part of City Hall's wide-ranging environmental program. Officials want to curb emissions, and the prohibition won support from the environmental community.
