Which of the following is NOT a category of road sign?

The correct answer identifies "Information" as not a category of road sign. In traffic sign classification, the common categories include Regulatory signs, which inform road users about laws and regulations; Warning signs, which alert drivers to potential hazards on the road; and Guide signs, which provide information about directions, distances, and services.

While "Information" might seem reasonable on the surface, it is not an officially recognized category in traffic sign systems. The term often overlaps with the term "Guide," which serves the purpose of providing navigational assistance, and it is important to differentiate between these established terms to avoid confusion. Understanding the standard classifications helps ensure that drivers can interpret the signs they encounter accurately.
