How to brake on ice
Keep a safe distance from other cars.
While tailgating is always a bad practice, it's especially dangerous in icy conditions. Stay at least 8 seconds behind the vehicle ahead of you.

Options:
[A]. If you're not used to winter driving, stay 10 seconds behind. To measure your following distance, pick a fixed point ahead of the vehicle you're following.
[B]. This is the distance you need to brake safely at any time. If you can, stay behind another car with a clearance high enough so you have enough clearance to enter and exit the vehicle safely.
[C]. Keep a firm eye out for oncoming cars and let them get as close to you as possible. Don't brake with your tires on the ice.
[D]. When a car passes you, look back for oncoming cars. Always wear the proper protective gear when driving around ice, such as gloves, wide-brimmed hats, and disposable helmets.
