He was waiting to make a left turn and pulled out right in front of another car who was driving srraight on the street that he turned onto. This caused the car to have to slam on the breaks and turn the wheel to the side to avoid hitting the truck. I was behind the car who had to slam the breaks. This caused me to have to slam on my breaks and also turn my wheel to the side to avoid slamming into the car in front of me. As a result the car behind me also had to slam the breaks to avoid hitting me. This caused several cars to swerve off of the road and into the side ditch to avoid hitting the car in front of them because the guy in the truck made a left turn i to oncoming traffic.
