There are only two applicable vehicle codes.
Quote:
21658. Whenever any roadway has been divided into two or more clearly marked lanes for traffic in one direction, the following rules apply:
(a) A vehicle shall be driven as nearly as practical entirely within a single lane and shall not be moved from the lane until such movement can be made with reasonable safety.
(b) Official signs may be erected directing slow-moving traffic to use a designated lane or allocating specified lanes to traffic moving in the same direction, and drivers of vehicles shall obey the directions of the traffic device.
Amended Ch. 450, Stats. 1975. Effective January 1, 1976.
22107. No person shall turn a vehicle from a direct course or move right or left upon a roadway until such movement can be made with reasonable safety and then only after the giving of an appropriate signal in the manner provided in this chapter in the event any other vehicle may be affected by the movement.
Amended Ch. 1996, Stats. 1959. Effective September 18, 1959.

So only two strikes against the other car. There are no law against changing in an intersection, though 21658a still applies.
At the same time, that was pretty bonehead to try to beat the yellow light that. 45 mph road has a yellow light for 5.0 seconds (the minimum yellow is 3 second for a slower speed road). You weren't anywhere close.
