Hey you, driving around with your headlights off while it's snowing outside- knock it off!
We've been driving around in this white stuff for quite some time now, so this shouldn't come as a surprise to you: you need to turn your headlights on, even if it's during the day.
Just ask the Wyoming, Minnesota Police Department, who put together a sarcastically informative video on a little known "anti collision device" that's installed in every single vehicle; even yours.
