What color is the flag for the lead vehicle?

• A. Blue
• B. Green
• C. Red
• D. Yellow

Answer: (A)

In this signaling system, colors carry meaning to identify roles quickly, so the lead vehicle is marked with a color that is easy to recognize and unlikely to be confused with warnings or permissions. Blue is chosen because it stands out against most backgrounds and isn’t normally used for danger, caution, or go signals. This makes it the clearest indicator of the lead vehicle and helps following vehicles coordinate smoothly. Red often signals danger or stop, yellow signals caution, and green signals go or safe, so using those colors for the lead could create mixed messages and increase confusion.
