Does driving with your lights on during the day seem a bit counterintuitive? You can see just fine, so why flip them on? Does it really make a difference?

It may. Studies have found that car accidents are less likely when your lights are on. The head-on crash, one of the most dangerous types of accidents, is specifically impacted by the use of headlights or daytime running lights. Though different studies are always going to come up with different percentages, the reduction is usually from five to 10 percent.

When driving, one of your goals should always be to reduce the odds of a crash. You can’t get them to zero. There’s always a chance that someone rear-ends you at a red light, for instance. Other drivers make mistakes all the time, and you cannot prevent that.

But, with things like defensive driving and choosing what hours you’ll actually drive, you can lower the odds. Avoiding heavy traffic times, like rush hour, can help. Increasing your following distances and staying alert can help. Everything drops the percentage points a little bit more.

And that’s where the five to 10% from headlights comes into play. It may seem low all on its own, but, when you combine it with everything else you’re doing, you can really see a difference. This is how safe drivers stay safe and avoid accidents.

Again, though, nothing guarantees that you will not get hit by someone else, and you must know what legal options you have if you do.
