What should drivers do if they cannot use lighted lamps?

When drivers are unable to use their lighted lamps, displaying flags as indicators serves as an important safety measure. Using flags can enhance visibility, signaling to other drivers that the vehicle is present on the road, especially in low-light conditions or inclement weather. This method effectively communicates to other motorists the presence of the vehicle, thus reducing the risk of accidents.

While bright clothing can help increase visibility of pedestrians or stationary objects, it does not adequately address the need for vehicles to indicate their presence on the roadway. Signaling with a vehicle horn may alert other drivers to some degree, but it does not provide a visual cue that is critical in ensuring safety. Reducing speed is always a prudent practice when visibility is compromised; however, it does not inform other drivers of the vehicle's location as effectively as flags do. Therefore, the use of flags is the most direct and reliable method for providing visibility when lighted lamps cannot be utilized.
