Depends on a lot of factors and as mentioned by ceejayoz, the routing is likely a lot more complicated than that, taking into account different trucks operating in the same areas, but I know of quite a few intersections (stop-light controlled rather than stop sign controlled) in my neighborhood where I prefer multiple rights to a left because right on red is allowed (if no oncoming traffic) and you can often make the 3 right turns much faster than waiting for the one left turn at a light.
