It would be my opinion that you are both At Fault. Car A should have been looking all around before backing out of a driveway. It sounds like car B made an illegal u turn and crossed double yellow lines. I would say that both of you are equally at fault. Just my opinion
Only when pulling in or out of a driveway. Commercial and residential alike.
One of the ways you can cross a double or single yellow solid line is when you entering or exiting a driveway
When two parallel solid yellow lines separate lanes of traffic, the only legal maneuver you can perform is turning left into a driveway on the opposite side of the road.
The average width of a single car driveway is between 10 and 12 feet. As for a double car driveway, it goes up to 20 feet.

enter a private driveway
A two-car driveway can comfortably fit two cars, side by side. The standard double car driveway is between 18 and 20 feet wide by 18 to 20 feet long.
The Quick Mix Theory

Yes, providing that you do not interfere with traffic already flowing on the roadway.
If I understand the question you were both backing at the same time into traffic? If that is the case, likely be deemed 50/50, or if one person had ''possession of the lane'' then the other party would carry most if not all of the negliegence/liablility This is similar to what happened to my car, but in my case, my car was still not quite out of the driveway when the other car hit my left tail light area with her rear bumper, so basically she backed out perpendicularly to the street, crossing 3 lanes. And this a 4-lane street with double yellow line.
You should never need to do so. If the driveway is on the opposite side of the road, find a way to enter it FROM that side of the road. If doing so isn't possible, then you have no choice-- enter the driveway by crossing the yellow lines.
