In California, about half the air pollution comes from cars and trucks. Fewer trips in your car or truck can help improve air quality. Even how you drive can reduce your car’s footprint. Take these into consideration when your are traveling on California roads: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Walk or ride a bike when possible. Take public transportation. Organize and condense errands into one trip. When driving, accelerate gradually and obey the speed limit. Drive less, particularly on days with unhealthy air. Maintain your vehicle and keep your tires properly inflated. Support the Smog Check Program. Report smoking vehicles to 1-800-END-SMOG. Travel lightly and remove any unnecessary items that may weigh down your vehicle. Limit idling your vehicle to no more than 30 seconds. When in the market for a new car, look for the most efficient, lowest-polluting vehicle or even a zero-emission electric car.
