Diamond Bar sits near major commuter routes and gets plenty of evening traffic. That means DUI crashes here often involve issues like:
- Traffic-camera or toll-adjacent footage gaps (timing matters)
- Complex intersection dynamics near busy corridors
- Multiple witnesses with partial, time-stretched observations
- Commercial delivery vehicles and workplace commute schedules that affect damages
Even when liability seems obvious, insurance companies may still contest details—especially around timing, impairment evidence, and injury causation.
