Michigan Driver's Training Level 1 Practice Test

Regulatory signs are those that tell you a rule you must follow. They’re designed to stand out and be read quickly, using colors that signal actions you need to take or obey. Red is used to indicate prohibitions and required actions (for example, stop signs and yield signs). White provides a high-contrast backdrop for clarity, and black is commonly used for the text or symbols on signs with white backgrounds, such as speed limits or other rules. Because regulatory signs use this mix to convey legal requirements, the colors red, white, and black cover the typical appearances you’ll encounter. Other color schemes correspond to different kinds of signs: blue and white for services or information, yellow and black for warnings, and green and white for directional or guide information.
