Many Sonoma County crashes happen in predictable real-world ways:
- Late-night event traffic: After festivals, concerts, and winery gatherings, the “who left first, who slowed down, and who was where” question becomes crucial.
- Tourist-heavy corridors: When visitors are involved, witnesses may be transient (driving through, stopping briefly, or leaving before documentation is complete).
- Dark-road visibility and distraction: Headlights, glare, and limited visibility can affect what officers and witnesses believed they saw.
- Multiple documentation sources: Surveillance video may exist (businesses, parking areas, nearby intersections), but it’s often overwritten quickly.
Those patterns don’t automatically determine liability—but they do shape how evidence is preserved and how liability is proven in a civil claim.
