What does a red triangle with an orange center indicate?

A red triangle with an orange center indicates that the vehicle is classified as a slow-moving vehicle. This symbol is specifically used to alert other drivers that the vehicle's maximum speed is typically 25 mph or less. It serves as a warning for motorists to approach with caution and to be prepared to slow down or change lanes if necessary.

The design of the symbol is intentional, as the bright coloration helps ensure high visibility, especially on roadways where slower-moving vehicles might be encountered. It's particularly relevant in rural areas, where you might see agricultural machinery or other slow-moving vehicles that could pose a hazard to regular traffic. Understanding this symbol is crucial for maintaining safety on the roads and ensuring that drivers are aware of potential obstacles.
