What should you do when you see signs that warn "lane closed ahead" in a work zone?

• Stay in the closed lane until instructed by construction workers to merge.
• Merge your vehicle safely into the correct lane as soon as it is safe to do so.
  Explanation:

  "As you enter a work zone, flashing signs, arrow signs, or signs that warn "lane closed ahead" mean you should merge into the correct lane when it is safe. Do not speed to the end of the closed lane and try to merge into the other lane."
• Drive to the end of the closed lane before attempting to merge.
• Ignore the signs and maintain your current lane until you reach the end of the closed lane.
