Waltham is a city where local traffic and regional commuting overlap. That mix creates patterns we see repeatedly:
- Merging and lane-change collisions in heavy flow, where a truck’s blind spots matter more than a typical car’s.
- Stop‑and‑go rear‑end impacts that become severe because of truck weight and stopping distance.
- Delivery and service vehicles making frequent turns and stops near retail corridors and side streets.
- Construction-related truck traffic moving in and out of active work zones.
These aren’t abstract issues—they shape the evidence that needs to be collected and the arguments insurers try to use (for example, blaming “sudden braking” in congestion, or claiming you “appeared out of nowhere” in a merge).
