#3. Always Have Your Headlights On
According to a recent study, you can reduce your risk of being involved in an accident by up to 32 percent simply by driving with your headlights on at all times. This seems like common sense -- obviously something that is lit up is going to be more visible, regardless of the time of day. And as long as other cars are driven by tired, distracted human beings, greater visibility equals less chance of having a hood ornament embedded in your skull. Yet almost nobody drives with their lights on during the day (and cars with automatic lights won't flick on until the sun goes down).
