When are drivers mandated to use headlights in Virginia?

Drivers in Virginia are required to use their headlights from sunset to sunrise and whenever visibility is reduced to less than 500 feet. This law helps ensure that vehicles remain visible in low-light conditions and during poor weather conditions, which significantly enhances safety on the road.

Using headlights during nighttime is crucial as it allows drivers to see the road ahead and spot potential hazards. Additionally, in conditions where visibility is compromised, such as fog, rain, or snow, turning on headlights ensures that not only can drivers see better, but they can also be seen by other road users, which is essential for preventing accidents.

The other options do not encompass the full scope of when headlights should be used according to Virginia's driving laws, particularly by neglecting important conditions like reduced visibility during the day or nighttime driving.
