The octagonal (eight-sided) shape is used for which sign?
-
A.
The stop sign posted at an intersection Correct
-
B.
The yield sign at a merge
-
C.
The Do Not Enter sign at a wrong-way ramp
-
D.
The crossbuck sign at a railroad crossing
The answer is "The stop sign posted at an intersection"
The octagonal shape is reserved for stop signs; no other regulatory sign in the manual uses the eight-sided outline. Drivers who treat yield and stop as interchangeable at an intersection, because both signs are red-and-white and both appear where traffic meets, are the ones who land on the yield sign in choice B.
The traps in the wrong answers
B. The yield sign at a merge
The yield sign is triangular with the point at the bottom, not octagonal. Treats yield and stop as interchangeable because both are red-and-white signs that appear at intersections.
C. The Do Not Enter sign at a wrong-way ramp
The Do Not Enter sign is square, with a red circle and a horizontal white bar inside it; its outline is not octagonal. Groups two red regulatory signs under one shape because both act to forbid movement.
D. The crossbuck sign at a railroad crossing
The crossbuck is an X-shaped sign at the tracks, not an octagon. A crossbuck identifies a railroad crossing; it does not by itself require every driver to stop. Carries over the association between railroad crossings and stopping to the shape question, picking the sign at the tracks instead of the octagon reserved for stop signs.
