Signs that are round or rectangular with a white and blue background are classified as informative signs. These signs are designed to provide information to drivers and pedestrians, such as directions, points of interest, or services available ahead. The blue and white color scheme is specifically used internationally to indicate non-mandatory information such as hospital facilities, parking areas, and rest stops, making it clear and accessible to all road users.

In contrast, warning signs typically utilize a yellow background with symbols or messages that alert drivers to potential hazards or changes in road conditions. Regulatory signs convey laws or regulations that must be followed, often employing red or white backgrounds to communicate restrictions or obligations. Prohibitory signs, as a subset of regulatory signs, specifically indicate actions that are not allowed. While the other categories of signs play important roles in road safety and navigation, the round and rectangular signs in question distinctly serve the purpose of relaying information, thus identifying them as informative signs.
