There are really two requirements of any civil lawsuit.  Did one party act below the appropriate standard of care (i.e. with negligence or recklessness) and did those actions cause the other party injury.  In your case, it is possible that either the cab driver or the other driver, or both, were negligent in their operation of their respective vehicles.  Since you and your friends all went to the hospital, it is likely that that negligence was the cause of your injuries.  Since police officers arrived at the scene, it is likely that there is a police report of the accident.  Your first steps to initiating a civil lawsuit is to obtain the police report and gather all of your medical records (even if it is just an ER report) relating to this accident.  The police report should identify the parties involved, their respective fault, and any applicable insurance policies.  Your medical records will provide an indication of the damages that you have suffered and/or will continue to suffer.  Once you have these documents, you should consult with and/or retain a personal injury attorney to discuss the merits of your potential case and whether it is likely that you will recover any monetary damages.

As long as this wasn't two years ago, I don't think it's a problem that you were rushed from the scene to the hospital.  A personal injury lawyer and his staff will be able to work back from your hospital records to the accident report, which will identify the owners and drivers of all the vehicles involved.  One place that you can find an attorney near you is our website, http://attorneypages.com

Don't wait to get the process started, if you were seriously hurt.  As passengers, there is almost no way for you to be at all at fault, so you get damages in full.
