Turn off your vehicle engine when parked for more than 30 seconds or waiting in lines or for passengers.
WHY? Idling continues to produce air pollution, smog and global warming, besides being harmful to health. It is more gas-efficient to turn off most warmed-up vehicles than to idle for more than 30 seconds.
Idling exhaust is especially hazardous to children around schools, as parents and buses wait for kids. Carbon monoxide reduces the ability of blood to bring oxygen to body cells and tissues. Children’s asthma symptoms increase as a result of car exhaust.
HOW? A brief warm-up period upon starting a cold car may be necessary, (1-2 mins.) but idling at every waiting location is not. To reduce air quality and health problems, it is recommended that you idle your vehicle no longer than 30 seconds — not only around schools, but everywhere you drive.
