In Michigan we have webcams on the front of our snow plows, in addition to their GPS location. This is useful for seeing road conditions throughout the state in places that don't have traffic cameras.

Just click the little icon that looks like a snowplow on this site. No plows out today, however...

Surely if you're planning to drive on the road, you'd want the webcam to be behind the snow plow?

Lighting behind a truck is poor (no white lights on the back), and it gives an idea of how bad the roads are getting between snow plows. This is useful since plows often run notably slower than normal traffic can safely run for the conditions.
