A work zone sign well ahead of the site tells drivers to merge left. When does the manual say you should act on it?
-
A.
After passing the first orange barrel in your lane.
-
B.
Only after the lane you are in physically ends.
-
C.
As soon as the signs indicate, not at the last minute. Correct
-
D.
Once you can see the workers on the roadway ahead.
The answer is "As soon as the signs indicate, not at the last minute."
The manual tells drivers not to wait until the last minute; the advance signs give enough time to act without impeding traffic. Drivers who hold off until the first orange barrel reaches their lane (choice A) mistake an in-zone guidance device for the trigger, when the advance sign has already given the instruction.
The traps in the wrong answers
A. After passing the first orange barrel in your lane.
The manual ties the required action to the advance sign, not to devices inside the zone; waiting for a barrel to appear beside you delays the move the sign already called for. Treats the in-zone traffic control devices as the cue to act, when the manual assigns that role to the advance warning sign.
B. Only after the lane you are in physically ends.
Waiting for the lane to physically end delays responding to the advance merge instruction until the last minute, which is exactly what the manual says not to do. Carries over the common habit of staying in a vanishing lane until it ends, rather than acting when the advance sign first appears.
D. Once you can see the workers on the roadway ahead.
The manual keys the action to the advance sign, not to first sight of workers; follow the advance sign's instruction without waiting to see workers. Uses worker visibility as the trigger when the orange advance sign is what the manual assigns that role.
