An operator approaching an oncoming vehicle within how many feet must select the lowermost distribution of light?

When operating a vehicle near an oncoming vehicle, it's crucial to prevent blinding other drivers with bright headlights. The law mandates that when you are approaching an oncoming vehicle, you must switch to the low beam headlights when you are within 500 feet of that vehicle. This is to ensure safe visibility levels for both drivers and to minimize the risk of accidents caused by glare.

Using low beams at this distance helps maintain adequate light for your own visibility while not impairing the visibility of the driver of the oncoming vehicle. Understanding this distance and the appropriate response is essential for safe driving practices.
