What type of signal do two yellow flags indicate?

Two yellow flags indicate that drivers should slow down to a specific speed, in this case, to 15 mph. This signal is typically used in contexts such as construction zones, race tracks, or other environments where reduced speeds are necessary for safety. The use of yellow flags is a widely recognized caution signal, alerting individuals to be aware of potential hazards or changes in driving conditions.

Slowing down to 15 mph allows for better control of the vehicle and enhances safety for both the driver and any workers or obstacles that may be present in the area. It essentially provides a buffer period for drivers to react appropriately to any unforeseen circumstances. Thus, this signal is crucial in maintaining order and ensuring safety in situations where full-speed travel could lead to accidents or injury.
