It is heartbreaking to hear such a story. My condolences goes out to both of their families. I would not advise anybody to drive in the snow during late hours. I'm sure they had very little experience driving in the snow.  We have to be more careful. We recently had a snow storm and even a slight mistake can lead to a fatal crash on the freeway. Icy conditions are unpredictable, and a hint of black ice is enough to spin a car out of control. Please be safe.
