You have to treat the red light as a stop sign. So you have to stop, look, THEN turn. Assuming there isn't a sign that tells you not to turn right at the red light.
Signs for 695 always say which direction you're taking it, and if you're using Google Maps, it will also tell you the direction you need. There are always mistakes with those sorts of map systems, certainly. But if I can navigate 695, as the mistress of terrible sense of direction, so can anyone else. And it's really just a big circle. If you go the wrong way, you can either get off and get back on the right way, or you can just follow it back around. NBD.
Anyway, were we thinking about getting food, or what? I really don't know where we can go that won't be overrun by otakus.
