High beam headlights will normally illuminate about _____ feet ahead of the vehicle?
  1. 150 to 250
  2. 250 to 350
  3. 350 to 500
  4. 500 to 1000
Explanation
Answer: C - High beam headlights that are working properly will normally have an effective illumination range of 350 to 500 feet. This distance will decrease, however, as headlights age or become dirty. Drivers should use their high beams when it is safe to do so as this allows much more time to see and to react to problems ahead of the vehicle. High beams should not be used when approaching other vehicles.
