What must a driver do when a reversible lane displays a steady red X?
- Leave the lane and never drive in it under that signal
- Enter the lane only to pass a slower vehicle
- Continue in the lane until the next intersection
- Use the lane if the roadway ahead appears clear
Answer: Leave the lane and never drive in it under that signal. A steady red X closes the lane to traffic. Leave it when safe and do not enter it simply because the pavement looks open. A passing maneuver, an upcoming intersection, or clear sight distance cannot override the lane signal. A steady yellow X means move out as soon as safely possible because closure is coming. The useful visual cue is simple: red X means stay out, while a downward green arrow permits travel in that lane.
