caution signal
Yellow light ahead
A caution signal warns of potential danger or the need to slow down.
On railways and roads, it typically appears as a yellow light between red (stop) and green (proceed): The caution signal gave drivers time to brake before the intersection.
The term extends to any warning indicator that something requires attention without demanding immediate halt.
