We all can play a part to help combat smog. Since one of the major causes of smog is emissions from vehicles, you can do your part by ensuring you're driving clean. Read on for helpful hints on driving clean.

1. Is your vehicle in-tune? A poorly tuned engine can consume an average of 10 per cent more fuel.

2. One equals 20. One poorly tuned vehicle can emit pollutants equivalent to 20 properly tuned cars.

3. Don't let your engine idle. Excessive idling pollutes. Turn off the engine whenever you can.

4. Under-inflated tires put pressure on fuel. Properly inflated tires improve fuel performance.

5. 90 is optimum. The best fuel economy for most vehicles is around 90 km/h.

6. Light is right. The heavier the car, the more fuel it burns. Avoid unnecessary weight.

7. Plan your trips. Save money by planning activities and combining errands to reduce the number of times you start your vehicle.

8. Share the ride. Carpooling or ride-sharing reduces the number of vehicles on the road.

9. Be aerodynamic. Reducing wind resistance on the highway cuts fuel consumption. Try rolling up the windows and opening the vents.
