Truck routes and congestion patterns in San Francisco create recurring risk zones. We routinely see serious incidents connected to:
- Freeway merges and sudden slowdowns on corridors like I-80, US-101, and I-280, where stop-and-go traffic turns a moment of distraction into a high-force impact.
- Downtown delivery density—double-parking, tight turns, and loading activity near office cores and retail corridors can place pedestrians, cyclists, and smaller cars in a truck’s blind spots.
- Hill grades and braking demands in areas with steep descents, where brake condition and driver technique matter more than people realize.
- Construction staging and detours, where lane shifts, temporary signage, and uneven surfaces increase the likelihood of sideswipes and squeeze-zone collisions.
These aren’t abstract scenarios. They shape what evidence matters and what a trucking company is likely to argue.
