Pennsylvania Practice Warning Signs

A curve warning sign is paired with a smaller yellow sign reading 25. What does the smaller sign show?

  1. A.
    The default rural speed limit
  2. B.
    The distance to the next warning sign
  3. C.
    The minimum speed required in the curve
  4. D.
    The highest speed you should travel around the curve Correct
The Why

The answer is "The highest speed you should travel around the curve"

The manual describes an advisory speed sign as giving the highest speed you should travel through the curve. It is not a minimum, a statewide limit, or a distance callout. Option C questions from confusing the yellow advisory placard with the black-and-white minimum-speed regulation.

Why the others miss

The traps in the wrong answers

A. The default rural speed limit

Advisory placards belong to the diamond sign beside them, not to a statewide default. This answer reaches for a familiar general speed number rather than reading the sign in context.

B. The distance to the next warning sign

The number on an advisory placard is a speed in mph, not a distance in feet. This answer reads any two-digit number below a sign as a countdown the way exit tabs use them.

C. The minimum speed required in the curve

Advisory placards give the top safe speed, not any required minimum. This answer confuses the yellow advisory with a black-and-white minimum-speed regulation.
