I have a couple more scenarios for you. Overdriving your headlights is a great way to hit something you don't see in time. The safe speed in average conditions on low beams is around 25 to 30 mph, and on high beams, it is around 45 to 50 mph. If there's any glare on the roadway from security lights and oncoming drivers, your safe speed drops 10 to 20 miles an hour. Related to this is glare from the sun or artificial sources. I lived in a small city with antique-style globe lamps on Main Street. The veiling glare made pedestrians invisible, and even if you knew about the glare and watched for pedestrians, you would still be surprised when they became visible halfway across the street in front of you.
