Don't be surprised if the insurance company tries to point the finger at you, putting as much fault on you as possible. Without the representation of an experienced motorcycle accident attorney, they will likely be successful.
Once you hire an attorney, they can refute this blame by:
Hiring an accident reconstructionist
Interviewing witnesses
Obtaining video surveillance footage
Reviewing police reports
Once you hire a lawyer, they will be the one to handle any blame the insurance company says you might have.
