How far must headlights illuminate persons and objects for safe driving?

The correct answer indicates that headlights must illuminate persons and objects at least 350 feet on high beam and 100 feet on low beam. This is crucial for safe driving, as having adequate visibility allows the driver to see potential hazards, pedestrians, and other vehicles in time to react appropriately.

When using high beam headlights, the increased distance of illumination significantly enhances the driver's ability to detect obstacles or persons far ahead, which is especially important on dark or rural roads without street lighting. The 100 feet visibility requirement for low beam headlights ensures that drivers can still see clearly without blinding oncoming drivers, which is vital in situations where vehicles are approaching from the opposite direction. This distinction between the two beams highlights the need for appropriate light usage based on driving conditions, promoting safety for everyone on the road.
