A 3-minute lesson from the Ohio course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
At night you can only see as far as your headlights reach, so hazards appear later and closer. Use your lights by the rules, use high beams wisely, and keep your eyes moving.
Headlights must be on:
Between sunset and sunrise
During rain, snow, fog or other unfavorable atmospheric conditions — at any time of day
Any time natural light doesn't let you clearly see objects 1,000 feet ahead
Any time windshield wipers are in use because of precipitation
It's 3 p.m. and a heavy snow squall cuts visibility. Turn on your headlights: rain, snow or fog require them regardless of time of day.
Put it into practice
On a dark rural road you're using high beams when an oncoming car appears. Dim to low beams, and look toward the right edge of your lane until it passes.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
Which of these requires your headlights to be on, regardless of the time of day?
Driving in a school zone
Any period of rain, snow, or fog
Driving on an interstate highway
Carrying passengers under 18
Answer: Any period of rain, snow, or fog
Lights must be on during any period of rain, snow, fog, or other unfavorable atmospheric conditions, regardless of the time of day.
