When I heard that WI Governor Scott Walker had just made it a law that driver's in that state are now required to have their headlights on when weather conditions limit visibility I was surprised.  I would have thought that was a law that would have been in affect for a long time.

I call that a common sense law.  It's more about being visible to others than it is for you to see where you're going.  When Ken and I are on the air and it's foggy out, we often get phone calls and Facebook posts from people complaining that others don't have their lights on.  Of course, it's not just when it's foggy.  MN's state law also mentions snow, rain and other weather conditions.

One important thing to remember is that your lights on low beam will be much more effective than you high beams.
