He would be at fault. You would share some fault for speeding. You would share some fault for hitting him on the right rear quarter. You would not be assessed fault for the speed because you'd need a police report to verify that you were speeding (assuming you don't admit to it). If the police report said you were speeding, you'd challenge it on the grounds that everyone who testified to your speeding was stopped and are not experts in the field of estimating absolute speeds (civilians are only experts when it comes to relative speeds). Speeding would be thrown out, along with the fault. You would not be assessed fault for the POI, since the stopped traffic caused you to not see the illegally turning vehicle until it was too late, so your expectation of being able to stop is reduced or eliminated.
End result: other guy 100%.
I take it you aren't a lawyer nor experienced in traffic law.
In reality there are too many variables we don't know to point any blame should the OP have hit this guy in the rear.
The general opinion that people have though is usually very wrong from what plays out in courts. There are many that still believe if one vehicle 'rear-ends' another they are always at fault. This is really not the case always, however; in the majority it is usually the person in the rear's fault.
There are even those purposely backing into others thinking they'd be getting free repairs/upgrades. Insurance companies have learned to determine this now.
