What is the typical background color of parking regulatory signs?

• A. Blue
• B. Yellow
• C. Green
• D. White

Answer: (D)

Regulatory signs convey laws drivers must follow, and parking rules fall into this category. They typically use a white background because white provides high contrast and makes the text and symbols easy to read at a glance, which is essential for legal information about parking. The text is usually black, with red used for prohibitions or emphasis on specific restrictions. Colors like blue, yellow, and green are reserved for other sign families (services, warnings, and directional information), not the standard parking regulatory signs. So the typical background color you’d see for parking regulatory signs is white.
