What kind of signs does the manual say govern merging lanes?
-
A.
Regulatory signs backed by a state statute.
-
B.
Guide signs with white lettering on green.
-
C.
Service signs mounted on blue backgrounds.
-
D.
Advisory and warning signs only. Correct
The answer is "Advisory and warning signs only."
The manual states plainly that there is no regulatory sign for merging lanes; only advisory and warning signs apply. Drivers who assume every road-behavior rule has a matching regulatory sign pick A, because a merge feels like the kind of rule a red-and-white sign should enforce.
The traps in the wrong answers
A. Regulatory signs backed by a state statute.
The manual says explicitly that no regulatory sign is associated with merging lanes. This answer assumes every driving requirement is paired with a regulatory sign, which the manual specifically denies for merges.
B. Guide signs with white lettering on green.
Green guide signs point drivers to destinations; they do not carry merge instructions. This answer confuses merge signage with the green expressway guide signs mounted on the same roads.
C. Service signs mounted on blue backgrounds.
Blue service signs identify roadside services, not merge behavior. This answer confuses merge signage with the blue service signs used for gas, food, and lodging.
