How far must a flare, electric lantern, or portable reflector be visible at night?

The requirement for a flare, electric lantern, or portable reflector to be visible at night is established based on ensuring sufficient safety and visibility on roadways. The correct distance of visibility is 600 feet. This standard is crucial for alerting oncoming drivers to the presence of an emergency situation or hazard, allowing them enough time to react appropriately, adjust their speed, or steer clear of danger.

Visibility at this distance helps in reducing accidents, especially in low-light conditions or during nighttime. A distance of 600 feet provides adequate warning to approaching vehicles, ensuring that they can see the warning device well in advance and take necessary precautions. This distance is typically in accordance with guidelines for road safety and emergency response protocols, emphasizing that having a higher visibility range can significantly enhance safety for both emergency personnel and motorists alike.
