Signs that warn "lane closed ahead" may indicate a work zone ahead. You should:
- Merge your vehicle into the correct lane when it is safe ✓
- Drive to the end of the closed lane before attempting to merge
- Understand that this sign is merely a suggestion and continue in the lane
- Speed up to merge as quickly as possible
Answer: A. Merge your vehicle into the correct lane when it is safe
You should merge your vehicle into the correct lane when it is safe.
Why this is the answer
The handbook says work-zone signs that warn of a lane closure mean you should move into the correct lane as soon as you can do it safely. It specifically tells drivers not to race to the end of the closed lane and force their way into the other lane. Moving over at first notice is described as calmer, more efficient, and safer. That matches merging when safe, not waiting until the lane runs out.
Why the other answers are wrong
- B. Drive to the end of the closed lane before attempting to merge — The handbook directly warns against driving to the end of the closed lane and trying to get into the other lane there.
- C. Understand that this sign is merely a suggestion and continue in the lane — Work-zone signs are not optional suggestions; the manual says to obey the signs.
- D. Speed up to merge as quickly as possible — The manual says not to speed to the end of the closed lane and calls for decreased speed and alertness in work zones.
Remember it
When you see the lane-closure warning, pick your lane early and settle in; don't treat it as a race to the merge point.
