When are drivers required to use their headlights in Arizona?

Drivers in Arizona are required to use their headlights from sunset to sunrise and during any time when visibility is less than 500 feet. This regulation is crucial for ensuring safety on the road, as headlights significantly improve visibility for both the driver and other road users in low-light conditions or adverse weather situations.

This requirement helps to prevent accidents by ensuring that vehicles are visible to others when there is reduced light, such as during twilight or nighttime, as well as in conditions like fog, rain, or dense snow where visibility is compromised. By mandating the use of headlights in these situations, the law enhances overall road safety and promotes responsible driving practices in varying environmental conditions.
