Headlights and light conditions

Key points

1. Turning on headlights when it begins to get dark or visibility is impaired is the law, not just parking lights.

Numbers to know

3 questions from the West Virginia practice test

1. 1. When should a driver turn on the headlights according to the handbook?

   1. When it begins to get dark or visibility may be impaired
   2. Only after another driver flashes headlights
   3. Only while traveling on an Interstate Highway
   4. Only between midnight and 5 a.m.
   Show answer

   When it begins to get dark or visibility may be impaired. The handbook says headlights should be used when it begins to get dark or whenever visibility may be impaired, including conditions such as fog, smoke, and extreme cloudiness. The rule helps a driver see and helps other road users see the vehicle. Waiting for another driver is too late, and the rule is not limited to Interstate travel or a narrow overnight period. Turn on the headlights early when light or weather starts reducing visibility, and keep the lighting system clean and in proper repair.

2. 2. When you meet another vehicle at night in West Virginia, within what distance must you dim your headlight beams?

   1. Within 100 feet of the other vehicle
   2. Within 500 feet of the other vehicle
   3. Within 1,000 feet of the other vehicle
   4. Only when the other driver flashes first
   Show answer

   Within 500 feet of the other vehicle. High beams blind the driver coming toward you, so the handbook sets the dimming distance at 500 feet. When you see an oncoming vehicle, switch to low beams before you are within 500 feet of it, slow down, keep to the right of your lane, and look toward the right edge of the road rather than into the other headlights. One hundred feet is far too late, one thousand feet is more than the rule requires, and waiting for the other driver to flash means you have already dazzled them.

3. 3. At a West Virginia stop sign or red light, must you come to a complete stop when you are only turning right?

   1. Only at night
   2. No, a rolling stop is allowed when no cross traffic is visible
   3. Only when a police officer is present
   4. Yes, a complete stop is required regardless of traffic, even for a right turn
   Show answer

   Yes, a complete stop is required regardless of traffic, even for a right turn. The handbook lists impatience as a bad habit that causes crashes, and the example it gives is the rolling stop. Regardless of traffic, you must come to a complete stop at a stop sign or red light, even when you are only turning right. Pressure from vehicles behind you and an empty cross street can tempt you to slow down instead of stopping, but the absence of visible traffic is not the test; the law requires the full stop. Stop behind the line or crosswalk, look both ways, and then make the turn.
