During good weather without ice or snow your vehicle needs at least 2 seconds between you and the car in front of you to be able to stop.
During bad weather that increases to a minute or even a few minutes so you need to stay farther back from other vehicles in front of you when driving on snowy or icy roads.
When driving on icy or snowy roads try to stay 5 or 10 feet farther back than you normally would during nice days without snow or ice.
The farther back you are the better but be sure to keep up with the flow of traffic but also drive a bit slower than your normally would.
When your car begins to slide on the ice do not panic but instead slowly remove your foot from the gas pedal to allow the car to slow down.
When you get slowed down then tap the brakes lightly and do not slam on the brakes because if you start sliding on the ice and slam on your brakes your car could start spinning around and go into oncoming traffic.
If the ice is not too bad then you can usually regain control after slowing down and then continue at a slower pace in your car until you get home.
Never drive too fast on icy roads and if you don't have to be on the roads then it's best to stay home and avoid a possible fatal accident.
So in short when your car begins to slide on ice you slowly remove your foot from the accelerator pedal and then within a few seconds you should have control over the vehicle but if not lightly press the brake pedal to help slow down the car some more until you regain control.
If you have too then pull off to the side of the road and get towed so that you do not get into an accident.
