Put yourself as far back as the '*' but please in lane position A. You're invisible for at least 175ft if you're directly behind a truck / van or tractor-trailer rig.
I drove a 36ft box truck in SFO for almost 6 years. Two collisions while making deliveries in teh city - lucky both with cages. First was a dimbulb who tried to squeeze between my truck and the curb. I was stopped, he took off my right mud flap and the front left corner and most of the left side of his Lexus. He still claimed I hit his car - even with all the damage showing that he was the one going forward. The second was a woman in a Mercedes who decided that my LOUD beeping backup signal, BRIGHT backup lights and four-way flashers all meant that I was going forward, so she pulled up to within 5ft of my lift-gate _while I was backing_. My lift-gate peeled her hood back to the firewall, the engine in her car was pushed under the passenger compartment. At 3mph. My 78,000lb truck didn't feel a thing.
You were VERY lucky that you weren't injured or squished dead. That sticker on the back of big trucks about blind spots? It's real. Truckers call the blind zone - "The DEAD Zone" for good reason.
One last bit for you - NEVER pass a truck on the right, especially in the vicinity of an intersection. Big rigs need room to swing and will pull left in their lane before initiation of a right turn, you can get squashed in the pinch zone. That rarely ends well.
