In a Texas work zone, what does a large flashing or sequencing arrow panel tell drivers?
-
A.
That an emergency vehicle is approaching
-
B.
That an active school zone is ahead
-
C.
That part of the road ahead is closed Correct
-
D.
That construction is now complete
The answer is "That part of the road ahead is closed"
The manual gives arrow panels the job of informing drivers that part of the road ahead is closed. Answer A shows up when a driver matches the panel's flashing lights to those on an ambulance or fire truck, though the panel is a stationary lane-guidance device unrelated to emergency response.
The traps in the wrong answers
A. That an emergency vehicle is approaching
Flashing arrow panels are stationary work-zone devices, not signals of an approaching emergency vehicle. This answer matches a work-zone panel's flashing lights to the flashing lights on an ambulance or fire truck.
B. That an active school zone is ahead
School-zone warnings use steady yellow flashers on a sign, not large arrow panels. This answer borrows the flashing yellow setting from a school-zone beacon and swaps in the wrong device.
D. That construction is now complete
The end of construction is marked by a separate rectangular sign, not by an arrow panel. This answer confuses the arrow panel with the END ROAD WORK sign that closes out the zone.
