According to the manual, which of the following is an example of a service sign?
-
A.
Diesel. Correct
-
B.
Deer crossing.
-
C.
Detour.
-
D.
School zone.
The answer is "Diesel."
The manual's Service Signs section lists six examples: HOSPITAL, TELEPHONE, FOOD, GAS, DIESEL, and LODGING, each a blue square or rectangle marking a service at the next exit. Test-takers who read "service sign" as any helpful sign along the road often pick Detour, but Detour is an orange work-zone sign routing traffic around construction, not a blue sign pointing to fuel or food at the next exit.
The traps in the wrong answers
B. Deer crossing.
Deer crossing is a yellow diamond warning sign, not a blue service sign. This answer treats any roadside advisory as a service sign instead of matching the blue color and square shape the manual names.
C. Detour.
Detour signs are orange work-zone signs, not blue service signs. This answer groups any wayfinding word with service signs when detour actually belongs to the construction sign family.
D. School zone.
School zone signs are warning signs, not service signs. This answer assumes school zone rides alongside hospital because both name a building drivers look for.
