Originally, there was a pair of flashing lights next to a sign that said “Overheight when flashing” that would light up if the sensor was tripped. Then they replaced it with traffic lights that would stop traffic and flash “OVERHEIGHT MUST TURN” like you see here if the sensor was tripped.
Of course, that caused the dumb truck drivers to just floor it and run the red light.
