About no entry signs
The no entry sign prohibits aircraft from entering an area — typically a one-way taxiway, or a road or pavement that looks like a taxiway but isn't one. It's a mandatory instruction sign, so it's red, with the white no-entry symbol: a circle with a horizontal bar through it, each edged in black.
