Show answer & explanationAnswer & explanation
Correct answer: C. The lane is about to be closed or reversed; prepare to move out of the lane safely.
A steady yellow 'X' lane use signal indicates that the use of the lane is about to change. Drivers must safely move out of that lane as soon as possible because it will soon be closed or its direction reversed. It's a warning, similar to a steady yellow traffic light.
Why the other options are wrong
- A. This is incorrect; a steady yellow 'X' is a warning to vacate the lane, not to stop within it.
- B. This is incorrect; while you need to change lanes, 'immediately' and 'to the right' are not always prescribed. The key is to move out safely.
- D. This is incorrect; emergency vehicle lanes are not typically indicated by a yellow 'X'.
