What category of information do yellow diamond-shaped signs convey?
-
A.
Possible hazards or changes in road conditions ahead Correct
-
B.
Required actions, such as stopping or yielding
-
C.
Routes, distances, and exit information
-
D.
Services available at the next exit
The answer is "Possible hazards or changes in road conditions ahead"
Yellow diamond signs are warning signs. They alert you to a possible hazard or a change in road conditions ahead, but do not by themselves require any action. Each sign category in Oregon uses a distinct color and shape pairing, so confusing warning signs with regulatory, route, or service signs is a common error on this topic.
The traps in the wrong answers
B. Required actions, such as stopping or yielding
Required actions are conveyed by regulatory signs, which are rectangular with black words or symbols on a white background. Misreading: Confuses warning signs with regulatory signs, which tell you what to do rather than alert you to possible hazards.
C. Routes, distances, and exit information
Routes and exits are shown on guide and route signs, not on yellow warning signs. Misreading: Confuses yellow warning signs with guide or route signs that convey navigation information.
D. Services available at the next exit
Services like food, gas, and lodging are shown on blue motorist service signs, not yellow warning signs. Misreading: Confuses yellow warning signs with blue motorist service signs that point to fuel, food, or lodging.
