Which of the following signs is rectangular?
- School crossing sign
- Railroad crossing sign
- Stop sign
- Speed limit sign ✓
Answer: D. Speed limit sign
The speed limit sign is the rectangular one, because regulation signs like speed limits are white rectangles with black or red letters or symbols.
Why this is the answer
The manual groups rectangular signs with regulation signs: white signs with black or red letters or symbols that tell you about rules for lane use, turns, speed, parking and similar requirements. A speed limit sign fits that description, so it is the rectangular sign listed. The other signs named belong to different groups in the manual's sign chapter — the yellow warning signs and the other regulation signs — so they are not the white rectangular type described.
Why the other answers are wrong
- A. School crossing sign — The school crossing sign is a warning sign, and the manual describes warning signs as yellow with black letters or symbols, not as the white rectangular regulation sign type.
- B. Railroad crossing sign — The railroad crossing sign is not one of the white rectangular regulation signs the manual describes for rules such as speed, lane use or turns.
- C. Stop sign — The manual does not list the stop sign among the rectangular white signs that alert you to special rules; the rectangular examples it gives cover rules like speed and parking.
Remember it
Picture the white rectangle: if the sign is white with black or red lettering about a rule, it is rectangular.
