Turn left and stop. When going straight, I hit the left front bumper, big lampshade and fender of the left turn car.

Should be the main responsibility of the left-turn car. The driving test theory test says that the right-turn car lets the left-turn car go first, and the turning car lets the straight car go first. When the car that hit you stops temporarily, you should turn on the left turn signal before restarting. In addition, before restarting, pay attention to whether there are other cars passing by. If so, you should slow down or stop to avoid.
