Who changed lanes? Not sure I understand, am going on the assumption you changed lanes, but hit the other party because they were speeding. You have a duty to not change your lane unless and until it is clear and safe to do so. If the other driver were speeding (and you can prove it) there would be some negligence assessed to the speeding driver. This is difficult to prove though. If you'd like to give me more details, then I could be of more assistance.
anytime someone is backing out of a driveway or parking spot, they are at fault. The other driver will only be sited for speeding.
Based on my experience investigating traffic collisions in Ca. I'd make the following conclusion based on the limited info provided; Driver A would not be at fault. Driver C would not be at fault. Driver B would be at fault for traveling at a speed unsafe for conditions. Insurance companies will probably place percentages of fault amongst all the drivers, however, under the vehicle code, driver B would be the one who would get cited if the investigating officer felt it was warranted.
It's the fault of the other driver. If the police were not present there isn't much either of you can do. If it was a fairly serious accident and damage done to the vehicles, police were at the scene they would know whose fault it was. Usually damage down the side of the car or a rear-ender is a good sign you weren't at fault and the other driver was.
Left turn (a) yields to oncoming traffic (b). Without a stop sign or traffic signal, driver b has the right of way.
Depends on exactly how it happened. From what you've told us, yes, the speeding driver would be responsible for all the damage if his speeding was the direct (and only) cause of the accident. But if you were trying to beat a red light or were pulling into the street from a driveway or alley, you are also at-fault.
Your question is neither clear or definitive. How ever the driver of the car that drove into the rear of another car is at fault. I assume that the car that was speeding a bit was not involved, you do not include this vehicle in the accident, but he has no culpability.
This is a situation known as 'Contributory Negligence." Both operators are at fault, and it will take a court to decide what percentage each one carries. The motorcycle rider was speeding illegally, apparently; and the driver of the car has the absolute responsibility to leave the private drive in safety. The statement that the driver did not have time to yield is a ridiculous statement, akin to "he appeared out of nowhere." Vehicles cannot defy the laws of physics, and transporters are not in use. I am not a judge, but I would say that the driver of the car leaving the driveway is at fault for the accident.
You are if you were pulling out of a driveway or alleyway. If you were at a side road it would depend on who had the right of way. If you had to stop but he didn't, you're at fault. If he had to stop but you didn't or if he ran a stop, then its his fault. The fact that he then hit two other cars is immaterial.
You are possibly both at fault. Speeding is negligence per se
It is driver B's fault because you now that driver A should stop because other cars are already driving so he should of stopped instead of you keep going
At fault driver
No. For example if a driver stops at green light and the driver to his rear hits him, it is the driver in front's fault.
