In a city like Waltham, crashes can involve more than just two vehicles and a simple exchange of information. Common friction points include:
- Commuter traffic and timing issues: Rush-hour collisions can create disputes about where each driver was in the lane and what signals were actually active.
- Pedestrian and crosswalk exposure: Injuries can be more severe, and insurers may challenge causation when symptoms develop over time.
- Construction and lane changes: Temporary traffic patterns can lead to blame shifting (“you should’ve seen me” / “you entered unsafely”).
- Surveillance evidence disappearing quickly: Businesses, building cameras, and traffic-related recordings may be overwritten or deleted unless preserved promptly.
When the other driver is uninsured, these issues can become leverage for an insurer to delay, reduce, or dispute the claim.
