A rectangular guide sign is mounted overhead directly above one lane of a Texas highway. According to the manual, what does the sign tell you about that lane?
-
A.
The lane exits ahead Correct
-
B.
The lane is closed to trucks and RVs
-
C.
The lane merges with the next lane
-
D.
The lane is reserved for slower traffic
The answer is "The lane exits ahead"
An overhead guide sign posted directly above a lane means that lane exits ahead. Option D is the trap: many drivers picture the far-right lane as the slow lane, and a driver who has been passed by faster traffic on the left reads any right-side lane marker as a slower-traffic instruction.
The traps in the wrong answers
B. The lane is closed to trucks and RVs
Truck and RV restrictions are posted on white regulatory signs, not on green overhead guide panels. This answer confuses the exit-lane sign with a truck-restriction sign posted on downtown or mountain routes.
C. The lane merges with the next lane
A lane-merge warning is a yellow diamond posted beside the road, not a green guide sign mounted directly overhead. This answer reads any lane-specific advance notice as a merge warning because merges are what drivers watch for first.
D. The lane is reserved for slower traffic
Overhead guide signs above a specific lane announce an exit, not a slower-traffic designation. This answer reads a right-side lane sign as slow-lane guidance, a habit built on freeways where slower drivers move right.
