the cars fault-obviously
You CAN stop on a freeway ramp. Sometimes it's mandatory, like when the ramp signal is red, or if there is a traffic jam on the freeway. You should not stop on a freeway ramp if you can help it because you are risking a ear end collision.
45 mph
Ramp, accelration area and merge area
The speed appropriate to the conditions.
In Oregon yes but it is not enforced
Sounds confusing, but there seems to be a fair amount of fault all around. Was car #2 pushing a disabled vehicle onto the highway, or did he rear-end #1 on the service ramp? If disabled, it shouldn't have been on the highway except behind a tow truck (I know, lots of us have done it, but it's still against the law.), so whoever was behind the wheel and the pushing driver were both at fault. And if it was an accident on the ramp, #2 was definitely at fault.
