What does a blue road sign indicate?

A blue road sign indicates motorist services, which is essential for drivers to understand as they navigate the roads. These signs are designed to provide helpful information related to services that are available to travelers, including locations of gas stations, rest areas, hospitals, and lodging. This functionality is particularly important for long-distance travelers or those in unfamiliar areas, as it helps them locate necessary services quickly and efficiently.

Warning signs, school zones, and speed limits are associated with other colors and designs to convey their specific meanings. Yellow and orange colors are typically used for warning signs, indicating caution or potential hazards ahead. School zones are often marked with fluorescent yellow-green signs, alerting drivers to areas where children may be present. Speed limits are usually shown on white rectangular signs with black text, specifying the maximum speed allowed in that area. Each color and shape in road signage has been standardized to help drivers easily identify the information they need to ensure safe and informed driving.
