Yellow square plaque with the black legend 35 MPH

What does the number on this plaque tell you?

Show answer

Correct answer: The speed that is safe for the condition ahead

An Advisory Speed plaque gives the suggested safe speed for the warned condition, such as a curve. It is not a legal speed limit.
