What colors make up the slow-moving vehicle symbol?

The slow-moving vehicle symbol is primarily made up of fluorescent orange and reflective yellow colors. These colors are specifically chosen for their visibility on roadways, especially in situations where a vehicle is moving slower than the normal traffic speed. The distinctive combination allows other drivers to clearly identify a slow-moving vehicle from a distance, promoting safety and helping to prevent accidents. The bright colors stand out against various backgrounds, ensuring that the symbol can be easily recognized, even in low light or adverse weather conditions.

Other color combinations do not meet the visibility and regulatory standards set for this particular symbol, which is why they are not considered correct.
