Leftmost lane takes leftmost lane, other lane takes any other lane.

Many intersections in my area use curved dashed lines to indicate turn lanes... https://safety.fhwa.dot.gov/intersection/other_topics/fhwasa08008/ui1.cfm https://safety.fhwa.dot.gov/intersection/other_topics/fhwasa... One of the stated reasons are intersections with multiple turn lanes, to help drivers know how to make the turn and stay in their lane.

  They're usually faded out or nonexistent in most of the roads I frequent. I wish they just painted one lane bright red and another lane bright blue. The whole lane. If it fades 90% it's still in-your-face clear and hard to mistake. Or if you're worried about colorblind people, use patterns. Fill one lane with random dots and another lane with random stars.

Easy to say, but that's not true in all places. Here's one where the left 2 lanes are left turn lanes, and the leftmost left turn lane turns into the 2nd from left lane. Big potential for accident for the right left turn lane to accidentally also turn into the same (2nd from left) lane and crash. And NO, they don't know a priori that the leftmost lane of the street they are turning into is a left turn lane. https://www.google.com/maps/@37.3626182,-121.8918193,3a,75y,72.04h,81.47t/data=!3m7!1e1!3m5!1sAt1j_h5FxrAreDk7obYclQ!2e0!6s%2F%2Fgeo1.ggpht.com%2Fcbk%3Fpanoid%3DAt1j_h5FxrAreDk7obYclQ%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D346.46674%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192 https://www.google.com/maps/@37.3626182,-121.8918193,3a,75y,...

  I've seen that as well and that only ever happens when the left most lane is also an exiting lane. It's not intuitive by any means but it's also consistent so if you know the rules and can see the road ahead, you'll be safe.
