Under what condition can strobe lights be legally used?

Strobe lights are legally permitted to be used when visibility is less than 500 feet, primarily to enhance the ability to see and be seen in poor weather conditions, such as fog, heavy rain, or during night-time operations. This threshold is significant because it sets a standard for when additional visual aids become essential to maintaining safety on the roads. Strobe lights provide a high level of visibility that alerts other drivers to the presence of vehicles, particularly emergency and service vehicles, helping to prevent accidents in low visibility situations.

Understanding the specific conditions under which these lights can be used is crucial for compliance with traffic laws and regulations, ensuring that all drivers can navigate safely during times when normal visibility is compromised.
