This sign means
- crew and equipment are working and you must obey the speed sign ✓
- there is an obstruction ahead
- crew and equipment are working and you must obey the speed sign during daylight hours
- you must obey the speed sign if you can see workmen on the road
Answer: A. crew and equipment are working and you must obey the speed sign
The sign means that crew and equipment are working and you must obey the speed sign.
Why this is the answer
The handbook lists a construction sign reading “Crew working — obey posted speed limit.” It explains that construction signs warn of construction and maintenance work, and drivers must pay attention to the warnings and obey the instructions on them. It also says to travel within the posted speed. That matches the meaning that workers and equipment are present and the posted speed must be followed.
Why the other answers are wrong
- B. there is an obstruction ahead — An obstruction ahead is not what this construction crew sign indicates; the passage is about construction and maintenance work and obeying the posted speed.
- C. crew and equipment are working and you must obey the speed sign during daylight hours — The passage gives no daylight-hours limit for this sign, so adding that condition is wrong.
- D. you must obey the speed sign if you can see workmen on the road — The passage does not say the speed applies only when you can see workmen; it says to obey the posted speed in the construction zone.
Remember it
Crew working sign: the posted speed still applies.
