Final answer:
When standard orange flags or flashing warning lights are used in conjunction with signs, they do not block the sign face. These flags or lights are used to draw attention to the sign and make it more visible to drivers.
Step-by-step explanation:
When standard orange flags or flashing warning lights are used in conjunction with signs, they do not block the sign face.
These flags or lights are used to draw attention to the sign and make it more visible to drivers. They are typically placed above or next to the sign, so they do not obstruct the sign face.
For example, in road construction zones, orange flags or flashing lights may be used with signs to alert drivers to hazards or lane closures.
