As a human driver, in this area, I've made a right turn there. (Well, not this intersection, the next right turn from it) https://www.google.com/maps/@47.6175579,-122.3456341,3a,90y,136.4h,84.69t/data=!3m6!1e1!3m4!1srX5fQAd13VbXqM3g4OxsOQ!2e0!7i16384!8i8192 https://www.google.com/maps/@47.6175579,-122.3456341,3a,90y,... Even Google Maps has a car turning right here. I've always read those signs that you can't turn right from the left lane. It's confusing, for sure. https://mynorthwest.com/1186128/slalom-seattle-monorail-columns/ https://mynorthwest.com/1186128/slalom-seattle-monorail-colu... This article seems to agree (and bonus, you can slalom through the columns). You can turn so long as you're not crossing lanes.
