Here is some advice on driving at night, culled from the pages of the Colorado Driver Handbook. You may want to pass this list along to your fleet drivers as a friendly reminder.
Use your bright lights when driving in rural areas and on open highways away from urban and metropolitan areas.
If you are driving with your high beam lights on or your low beam lights with fog lights on, you must dim them before coming within 500 feet of any oncoming vehicle so the oncoming driver is not blinded by the glare.
When following another vehicle, you must use your low beam lights, with your fog lights off, if you are within 200 feet of the vehicle ahead of you.
Never look directly into an approaching car's headlights. As the car draws near, watch the right edge of your lane, noting the position of the oncoming car out of the corner of your eye.
When driving through fog at night it is best to use your low beam lights and fog lights, if you have them. Driving with high beam lights is like shining your lights on a mirror.
Be alert to vehicles, particularly darker vehicles, traveling after sunset without their headlights on.
