Turn your lights on!

Wasn't that fun? No, not really... To use the vernacular, it sucked big time. What awful weather! And it's not over yet.

Bad weather seems to bring out the worst in drivers. I'm going to have a quick rant about people who drive in the rain without headlights.

Headlights aren't just there to help you seen in the dark. They are also there to make it easier for people to see you. If you've turned on your windscreen wipers to help you see through the rain, how about you turn your headlights on so that other people trying to see through the rain have a better chance of seeing and avoiding you. Especially if you happen to have a car the colour of a wet road...

I don't want to have to stop and help out at an accident in the pouring rain because someone didn't think that being visible on the road was a good thing.
