Final Answer:
Information signs are typically a) blue or green.
Step-by-step explanation:
Information signs on roadways are commonly designed in blue or green colors. These colors are used to indicate that the sign provides non-regulatory information to drivers. Blue signs are often used for services such as rest areas, hospitals, or tourist information, while green signs are commonly used for directional guidance, distance, and other informational purposes.
These color conventions assist drivers in quickly identifying the type of information a sign conveys. Red is typically reserved for regulatory signs, yellow for warning signs, and black for regulatory and guide signs.
Understanding these color codes enhances road safety by allowing drivers to interpret and respond to information promptly and appropriately.
In summary, the correct answer is a) Blue or green, as information signs are commonly presented in these colors to distinguish them from other types of traffic signs.
