When must headlights and taillights be used?

  1. 30 minutes after sundown and 30 minutes before sunrise

  2. During severe inclement weather

  3. At all times while driving

  4. When unable to clearly see other vehicles 300 feet away

The correct answer is: 30 minutes after sundown and 30 minutes before sunrise

Headlights and taillights should be used 30 minutes after sundown and 30 minutes before sunrise to ensure visibility on the road. Option C is incorrect because it suggests that headlights and taillights should be used at all times while driving, which is not necessary during daylight hours. Option B is incorrect because headlights and taillights should be used in all types of weather to increase visibility for other drivers, not just during severe inclement weather. Option D is incorrect because it only applies to situations where visibility is limited by distance, not time.
