You can can sue but you can recover only economic damages (past and future wage loss, medical expenses and property damage). Under Civil Code 3333.4 you cannot recover pain and suffering damages if you were operating a vehicle in violation of Section 23152 or 23153 of the Vehicle Code, and were convicted of that offense.
It's difficult to fully understand what you are asking. You should consult a personal injury attorney in your area and get a free consultation. good luck!
