Texas Practice Warning Signs

According to the Texas manual, which sign shape is reserved exclusively to warn of hazards on roads or adjacent areas?

  1. A.
    Pennant
  2. B.
    Round
  3. C.
    Octagon
  4. D.
    Diamond Correct
The Why

The answer is "Diamond"

The manual assigns the diamond shape one job: to warn of existing or possible hazards on roads or adjacent areas. Drivers who remember pennants as part of the warning family reach for choice A, but the pennant's warning is narrower: advance notice of no-passing zones only.

Why the others miss

The traps in the wrong answers

A. Pennant

The pennant is reserved for advance warning of no-passing zones, not for general hazards. Remembers only that the pennant belongs to the warning family and picks it as the general hazard shape.

B. Round

The round shape is reserved for railroad advance warning signs, not for general hazards. Recalls a round sign at a railroad crossing and stretches that memory into a general warning role.

C. Octagon

The octagon is reserved exclusively for stop signs, not for general hazard warnings. Assumes the octagon's high recognizability makes it a general-purpose warning shape.
