Minnesota Permit Practice Test

What class of sign is indicated by a white color?

1. Warning

2. Regulatory (with exceptions for railroad signs)

3. Informational

4. Construction

The correct answer is: Regulatory (with exceptions for railroad signs)

A white-colored sign is classified as regulatory. These signs communicate laws, regulations, and rules that road users must obey to ensure safety and compliance while driving. Common examples include speed limit signs, parking regulations, and no turn signs. The white color signifies that compliance with the message is mandatory, and violations may result in penalties. In contrast, warning signs typically use colors like yellow or orange and are meant to alert drivers to potential hazards ahead, while informational signs can include a wider variety of colors and serve to provide guidance or information. Construction signs often feature bright colors such as orange to ensure high visibility in work zones. Additionally, while railroad signs can sometimes be white, they are exceptions and are generally categorized differently from standard regulatory signs.
