What is required to be carried in place when lighted lamps are not needed?

The requirement to carry two red flags when lighted lamps are not needed is rooted in safety regulations related to road and vehicle operations. The use of red flags serves as a visual warning to other drivers, indicating the presence of a vehicle that may be stationary or moving slowly, thereby ensuring safety in situations where visibility is compromised or when conventional lighting is not sufficient. This measure helps prevent accidents by alerting other road users to potential hazards.

In contrast, blue flags, emergency cones, and reflective vests are useful for various other specific situations, such as directing traffic or marking road construction areas, but do not fulfill the specific requirement to indicate a vehicle’s presence when lighted lamps are not necessary. Therefore, carrying two red flags is crucial for road safety adherence in this context.
