Pennsylvania Practice Regulatory Signs

According to the manual, what shape is a YIELD sign?

  1. A.
    Diamond with four sides
  2. B.
    Octagonal with eight sides
  3. C.
    Triangular with three sides Correct
  4. D.
    Rectangular and vertical
The Why

The answer is "Triangular with three sides"

The manual states YIELD signs are triangular (3-sided) in shape. Test-takers who pick octagon are recalling the STOP sign named just above YIELD in the same regulatory-signs section, and reach for it because STOP and YIELD share the red-and-white color scheme.

Why the others miss

The traps in the wrong answers

A. Diamond with four sides

The manual gives YIELD a three-sided triangular outline, not a four-sided diamond. This answer borrows the diamond outline associated with warning signs and applies it to a regulatory right-of-way sign.

B. Octagonal with eight sides

The manual reserves the octagon for STOP, calling it the only 8-sided sign on the highway. This answer swaps YIELD with STOP because they are the red-and-white regulatory signs the manual names together in the same section.

D. Rectangular and vertical

The manual assigns vertical rectangles to SPEED LIMIT and similar posted rules; YIELD keeps its own three-sided outline. This answer defaults to the vertical-rectangle shape the manual names as the usual regulatory outline without recalling that YIELD is called out as an exception.
