Overdriving your headlights
You are overdriving your headlights when you go so fast that your stopping distance is farther than you can see with your headlights. This is a dangerous thing to do, because you may not give yourself enough room to make a safe stop. Reflective road signs can mislead you as well, making you believe you can see farther than you really can. This may cause you to over-drive your headlights if you are not careful (Diagram 2-58).
