Summer sunshine, heat and car exhaust create a toxic cocktail -- ozone pollution. Ozone can cause respiratory problems and even permanent lung damage. Here are some steps you can take to cut down on pollution when you drive:
Drive less, especially during peak traffic periods or hot days.
Avoid revving or idling engine over 30 seconds.
Fill gas tank during cooler evening hours to cut down on evaporation.
Keep your tires properly inflated and aligned.
