Driving safety

Experts say the best way to avoid an accident is to stay off the roads. 

Drivers can prepare for getting stuck in cold weather by putting a blanket, snacks, and water in their car.  Make sure your cell phone is charged or have a charger with you.

Here are a couple of other tips from driving experts:

-   Leave 600 feet, or about six car lengths, between your vehicle and one ahead of you.

-   If you hit ice, don't accelerate or slam on the brakes.

-   If you have anti-lock brakes, just press gently. The brakes will do the work for you

 -   If the rear of your car starts sliding in one direction, gently steer into the same direction.
