When flagging at night, what is true regarding retroreflectorized flags?

When flagging at night, the use of retroreflectorized flags is important for visibility and safety. However, if the flagger station is well-lit, the retroreflectorization of flags becomes less critical because the illumination provided by the floodlights enhances visibility. In this scenario, the bright lights compensate for the absence of retroreflective material since they allow drivers to see the flagger and the signal being given. Therefore, the statement that retroreflectorized flags need not be used if the flagger station is floodlit is accurate. It highlights a practical approach to flagging in nighttime conditions, allowing for flexibility based on the available lighting.
