I entered the right-most lane of a 5-lane one-way highway from a parking lot. I wanted to turn left ~8 car-lengths later at the next intersection joining another one-way road and freeway on-ramp.
I negotiated each lane change independently. The intersection lights turned red and I was in the 2nd-most left-lane, at the front, left-indicators on.
Beneath my car was visible left-hand turn and straight arrows. I recall another car on my left making a left-hand turn.
A police officer must have been behind them, as once I turned, I was pulled over "for cutting him off". The left-hand turn arrow in my lane was a "gentle-left" onto the freeway on-ramp.
How to fight? Mistake of fact on left-turn arrow? CVC22100 "as close as /practicable/ to the left edge" given I'd just entered the 5-lane road?
