Even if the wreck looks “ordinary,” truck cases tend to involve layers of responsibility. In California, insurers often focus on two things early:
- Causation (whether your injuries were caused by this crash), and
- Documentation quality (whether your medical treatment and work-loss records are consistent and timely).
In Mill Valley, that’s especially important because:
- Commute congestion can complicate fault questions (sudden lane changes, braking patterns, and following distance).
- Tourism-heavy traffic can mean more witnesses, but also more conflicting accounts from different vantage points.
- Pedestrian and cyclist proximity near certain corridors can expand the scope of what must be evaluated and documented.
A calculator may not account for how these local circumstances affect liability evidence and the insurer’s willingness to negotiate.
