One who cannot drive in blizzard conditions, or chooses to do so and is not prepared. Typically drives a small compact car with very low ground clearance and only 2WD. Will charge a snow bank in hopes of making it through.

Some Bliztard is blocking the road. They abondoned their car so I can't help pull them out.
