Many people expect a calculator to produce a number that matches what insurance will offer. In practice, California trucking claims are often negotiated around two things:
- Liability evidence (who caused the crash and why)
- Medical and wage documentation (what the injury actually cost)
If either piece is thin, adjusters frequently reduce offers—even when the injury feels obviously serious to you.
Also, California follows comparative fault rules. That means if an insurer argues you share responsibility, it can affect the final value. A tool may not accurately model the specific fault arguments likely in your case.
