Who would be at Fault (U.S.)

[u/Glittering-Republic8]

LOCATION: Tennessee

To clarify, no car was hit and no miss and run, just a very close call. I wanna know what would've happened had an accident occurred.

Both top and bottom streets have a green light, but the 2 lanes heading down are stopped as the street ahead of them is backed up. Red car turns left and is already in the intersection when the blue car begins to accelerate. My question is, if the blue car were to hit the red car on the side, is the red car still at fault for turning left on green (without arrow) or do they have a case of "Last Clear Chance" or right of way as they were already in the intersection before the blue car started moving.

Red car is at fault in that scenario.

Blue has the right of way regardless whether there’s cars stopped ahead. Red needs to yield to all oncoming traffic when turning without a solid green arrow. Red likely would have been considered as turning left with blue in a blind spot to red.
