What is the minimum distance low beams must reveal persons and vehicles?

  1. 50 feet

  2. 75 feet

  3. 100 feet

  4. 150 feet

The correct answer is: 100 feet

The minimum distance that low beams must reveal persons and vehicles is 100 feet. This distance is critical for ensuring that drivers have enough visibility to see pedestrians, cyclists, and other vehicles under various conditions, especially at night or in low-light scenarios. By being able to detect individuals and obstacles ahead of them with this range, drivers can react appropriately and safely, reducing the risk of accidents. The standard for low beam headlights is established to provide an adequate sight distance that enables drivers to make informed decisions. This guideline helps create safe driving environments by setting a clear expectation for visibility, ensuring that all vehicles on the road can be seen before they come too close. The other distances listed do not meet the minimum necessary for adequate visibility while ensuring the safety of all road users.
