Most regulatory signs (other than the red prohibitive ones) use which color scheme?
-
A.
Green panels with route numbers and exit destinations.
-
B.
Blue panels listing nearby food, gas, and lodging services.
-
C.
Black words or symbols on a white background. Correct
-
D.
Black symbols on yellow, marking hazards ahead.
The answer is "Black words or symbols on a white background."
Regulatory signs that tell you what to do, like speed limits, lane use, and one-way arrows, are rectangular with black words or symbols on a white background. The color tells you the category before you read the words. Yellow is for warning signs, green for guide and information, blue for motorist services. Memorize the color, not just the wording. Carrying the yellow-with-black scheme from warning signs over into the regulatory category is what leads a driver to D.
The traps in the wrong answers
A. Green panels with route numbers and exit destinations.
Green panels are guide signs that show exits and route directions. This answer confuses guide and information signs (green) with regulatory signs.
B. Blue panels listing nearby food, gas, and lodging services.
Blue panels point to motorist services like food, gas, lodging, and hospitals. This answer confuses motorist-services signs (blue) with regulatory signs.
D. Black symbols on yellow, marking hazards ahead.
Yellow with black symbols describes a warning sign, not a regulatory sign. This answer confuses the warning-sign color scheme (yellow with black) with the regulatory-sign color scheme.
