Answer

Safely change lanes to the right or pass the work vehicle on the right side as indicated.
Electronic arrow boards in work and maintenance zones are designed to provide clear, early visual guidance. A flashing arrow pointing down to the right explicitly directs drivers to merge into the right lane or pass to the right of the obstruction.

Step-by-Step Solution

1
Identify the function of the special zone traffic control device
Recognize that an electronic flashing arrow board is used in work zones to signal an upcoming lane closure or lane transition.
Arrow boards visually warn drivers far in advance so traffic can merge smoothly.
2
Determine the required driving action based on the directional signal
Follow the direction of the flashing arrow by moving into the open lane to the right.
The arrow points toward the safe path of travel, steering traffic clear of the closed lane and maintenance crew.
