it means that your going to fast to stop when something comes into the view of your headlights.
make sure you can stop in the distance you see ahead of you.
At night with your headlights on you can only see just so far down the road. Overdriving your lights is driving so fast as to not be able to react to something that is beyond the beam of your lights.
If you are overdriving your headlights and see an object ahead, you should slow down immediately to ensure you have enough time to react. Overdriving your headlights means you are not able to stop within the distance illuminated by your lights, increasing the risk of a collision. Slow down to maintain control and avoid a potential accident.
It means driving at such a speed that you can't see upcoming road hazards because your stopping distance is greater than the effective illumination of your headlights.
"Overdriving" HeadlightsYes, it's very easy by simply driving too fast, BUT... it's extremely dangerous!!!!!!
the speed you are travelling in a vehicle is faster than your headlights are allowing you to see in front of you. If your headlights were very dim and you could only see a very short distance ahead it would be very easy to overdrive your lights. Or like running as fast as you can, in the pitch dark, in a place you've never been before, with a flash light that is so dim you can barely see 12 inches ahead
Drive SLOWER than 80 miles per hour. Slow down. Over driving your headlights means while night driving you don't have enough reaction time between when you see the animal in the middle of the road and you hit him. Slowing down allows a longer time between the area you see and time your car arrives at it.
Use your high-beam headlights at night whenever it is legal and safe.
turn on your headlights
Headlights need to be used at night, when it is dark, and when windshield wipers need to be used.
You would not drive it at night or when the law says you must display headlights.
