You are driving at night and another vehicle is approaching from the opposite direction. Your headlights:

1. Should be on their high beam setting.
2. Should be on their low beam setting. ✓
3. Should be off. Use your parking lights.
4. May be on either their high or low beam setting.

Answer: B. Should be on their low beam setting.

When another vehicle is approaching from the opposite direction at night, your headlights should be on their low beam setting.

Why this is the answer

The Texas handbook says to use low beams when you are within 500 feet of an approaching vehicle. It also tells you to slow down at night and to avoid looking straight into the other driver's headlights, shifting your eyes down and to the right. High beams in that situation are not what the handbook calls for; the low beam rule is listed specifically for oncoming traffic. So as the other vehicle comes toward you, switch to low beams and keep your attention on your lane.

Why the other answers are wrong

• A. Should be on their high beam setting. — High beams are not the setting the handbook lists for an approaching vehicle; it specifically names low beams within 500 feet of oncoming traffic.
• C. Should be off. Use your parking lights. — Turning your headlights off and using parking lights is not the night-driving rule here; the handbook requires headlights and calls for low beams near approaching vehicles.
• D. May be on either their high or low beam setting. — Either setting is not correct because the handbook singles out low beams when a vehicle is approaching from the opposite direction.

Remember it

Think 'low for oncoming': when another car comes toward you, dim your lights.
