A left-curve warning sign posted above a yellow “25 MPH” plaque means:

Correct answer: D – Curve left with an advisory speed of 25 mph
The upper sign warns that the roadway curves left, while the plaque provides a 25-mph advisory speed for that condition. It is not a minimum speed. Drivers must still travel at a reasonable and prudent speed, and weather, visibility, traffic, or pavement conditions may require a speed below the advisory value.
