The man behind the wheel of this car was doing a little over 60 km/h (37 mph) when he started to lose control and, unfortunately didn't manage keep his vehicle on the road.
Now, whether it's snow, ice or just slush, driving at a low speed is the best advice for any type of slippery road surface.
According to the video's description, other drivers pulled over and offered assistance. Judging by the sounds coming from the car after the crash, the man was conscious and moving.
While the situation was dire from the moment the car began to slide around, it does look as though a more experienced hand might have prevented it, potentially stopping the car from going over the snow bank.
It's also possible that the car could have started to slide even if the driver was traveling at a lower speed; however, this would have given him more time to react.
