Which type of panel may be used in work zones to guide drivers into specific traffic lanes?

• A. large flashing or sequencing arrow panels
• B. standard stop signs
• C. traffic cones
• D. portable barrier walls

Answer: (A)

Large flashing or sequencing arrow panels are specifically designed to provide clear guidance to drivers in work zones. These panels use lighted arrows that can change directions or sequences to indicate the correct path for vehicles, directing them safely around or through construction areas. Their visibility and dynamic nature make them highly effective for informing drivers of sudden lane changes, detours, or closures, especially in environments where conditions may change rapidly. Standard stop signs are typically used to control traffic at intersections but do not provide directional guidance for lane changes in work zones. Traffic cones serve to mark off areas but lack the ability to convey specific lane guidance effectively, while portable barrier walls are used to physically separate areas and ensure safety but do not direct traffic with lighted indications like arrow panels do.
