A lane above the roadway is marked with a steady red X lane signal. What does that mean for you?
-
A.
The lane is about to close and will soon show a yellow X.
-
B.
Stop briefly in the lane, then continue when it is clear.
-
C.
Never drive in a lane displaying the red X above it. Correct
-
D.
The lane is open only to emergency and public transit vehicles.
The answer is "Never drive in a lane displaying the red X above it."
A red X over a lane means the lane is closed to traffic in your direction, and you may not drive in it. Drivers who learned HOV and bus-only lane signage first read the red X as another restricted-access marker, but on Florida roadways the red X is a full closure, not a lane reserved for a class of vehicle.
The traps in the wrong answers
A. The lane is about to close and will soon show a yellow X.
That sequence describes the yellow X, which warns the lane is about to close; the red X is already the closed phase. This answer reverses the yellow-X warning meaning with the red-X prohibition, applying the 'about to change' phase to the wrong lane signal.
B. Stop briefly in the lane, then continue when it is clear.
The lane is closed to your direction of travel; the red X is a prohibition, not a stop-then-go signal. This answer borrows the stop-and-proceed rule from a flashing red intersection signal and applies it to an overhead lane marker.
D. The lane is open only to emergency and public transit vehicles.
The red X closes the lane to all drivers in your direction; it does not designate a restricted-use lane for emergency or transit vehicles. This answer confuses the red X with the overhead HOV or bus-only markers used on Florida expressways to grant restricted access to certain lanes.
