An X-shaped white sign with black lettering mounted at a railroad crossing is called a:
-
A.
Chevron sign
-
B.
Pennant sign
-
C.
Diamond warning sign
-
D.
Crossbuck sign Correct
The answer is "Crossbuck sign"
The X-shaped white sign with black lettering mounted at a railroad crossing is the crossbuck. Chevron is the tempting wrong pick because the word evokes an angular geometry and drivers reach for it before checking that chevrons belong at sharp curves, not at railroad crossings.
The traps in the wrong answers
A. Chevron sign
Chevron signs mark sharp curves with a directional arrow, not railroad crossings. Grabs another named warning sign learned in the same chapter without checking which one the manual pairs with the tracks.
B. Pennant sign
Pennants mark no-passing zones on the left side of the road, not railroad crossings. Confuses the crossbuck's unusual X form with the pennant, another sign named for its distinctive angular geometry.
C. Diamond warning sign
Diamond warning signs cover general hazards, not the specific hazard of a railroad crossing. Falls back on the rule 'warning signs are diamonds' when the crossbuck's dedicated X form does not come to mind.
