SALT LAKE CITY (AP) -- Salt Lake City officials are urging residents to turn off their cars if they plan to idle for longer than 10 seconds.
The city's Office of Sustainability has launched a campaign called "Turn your key, be idle-free."
Vicki Bennett, the office's director, wants residents to avoid drive-thrus and instead park and walk into restaurants. Better yet, she says, bike or walk, take public transit or carpool.
The city's effort comes as concerns rise about annual summer increases in ozone pollution, which can irritate the respiratory system and exacerbate pre-existing medical conditions in some people.
