## Prepare for winter driving 

In B.C., we need to make sure our vehicles are prepared for winter driving conditions: 

• Make sure your car’s battery is in good condition. 

• Check the exhaust system. Any leaks can be extremely dangerous because carbon monoxide can collect in cars when the windows and vents are closed. 

• Replace oil and other fluids with winter‑grade products. 

• Install four snow tires. This will improve vehicle handling and control when you’re driving through slippery conditions. 

Using chains on icy roads is a good idea. Make sure you are familiar with how to mount chains on tires — practise putting them on your vehicle before you need to use them. 

In extremely bad conditions, it may be safer to park your vehicle than to continue driving. 

## Driving and the environment 

Cars and trucks use over half the world’s yearly oil supply. We know there is a limited supply of oil. Automobiles and light-duty trucks emit almost two-thirds of the common air pollutants in the Lower Fraser Valley (Greater Vancouver Regional District, 1998 Emissions Inventory). 

Most air‑conditioned vehicles manufactured before 1995 also contain chloroflorocarbons (CFCs) which are a major cause of the depletion of the ozone layer of the earth’s atmosphere.
