Weymouth’s traffic patterns create a predictable mix of risk:
- Rush-hour compression on South Shore routes. Stop-and-go flow increases rear-end impacts and chain reactions, especially when a heavy truck can’t stop as quickly as a car.
- Frequent merging and lane shifts. Areas near highway ramps and major intersections can turn a routine merge into a sideswipe or underride-type impact.
- Delivery and service vehicle volume. Box trucks, trash/recycling trucks, construction haulers, and regional tractor-trailers are common on local roads—often operating on schedules that reward speed and “making up time.”
These aren’t abstract issues. They shape what evidence we look for and which companies may be responsible.
