Shown beneath a curve warning sign, what does this yellow plaque communicate?
Correct answer: An advisory maximum of 35 mph for the warned condition
A yellow advisory-speed plaque accompanies a warning. It differs from a white regulatory speed-limit sign and does not justify driving too fast for weather, traction or visibility.

What should you expect beyond this work-zone warning?
Correct answer: A flagger controlling traffic ahead

What does the illustrated four-corner light pattern communicate when flashing on a work-zone arrow board?
Correct answer: Caution, without a specified merge direction
This is a caution display. Pennsylvania's manual associates it with work beside the travel lane; unlike an arrow, it does not specify a merge direction.

What does this yellow panel mean for the highway lane beneath it?
Correct answer: The lane becomes an exit ramp instead of continuing through the interchange
