This is in Ohio. I’ve seen Red, Yellow, Green, Flashing Red and Flashing Yellow. Never see alternating Red/Yellow flashing. What does this mean?
The cashier at BP said:
flashing red = treat as stop sign
flashing red and yellow = proceed with caution but don’t have to stop
flashing yellow = treat as green.
Tried to set her straight (flashing yellow=caution, flashing red and yellow = invalid pattern, malfunctioning light, treat as 4-way stop) but she was having none of it.
Called the highway patrol, who notified the Dept of Transportation.
