A 3-minute lesson from the Texas course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Night driving is much more dangerous than driving by day because many people don't see as well in the dark. Drive trips in daylight when you can, never drive tired, and use your headlights exactly when the law requires.
Know the rule
Slow down at night and make sure you can stop within the distance lit by your headlights.
Use headlights from 30 minutes after sunset until 30 minutes before sunrise, and any time people or vehicles can't be seen clearly for at least 1,000 feet.
Driving so fast your stopping distance is longer than the distance your headlights light. For stopping purposes, low beams are limited to 45 mph and high beams to 65 mph.
You're on a dark country road with high beams on when a pickup's headlights appear over a hill ahead. Switch to low beams once it's within 500 feet, and look toward the lower right edge of your lane until it passes.
Check your understanding
