San Juan traffic is shaped by daily commuting, school zones, and frequent movement through busy corridors. That’s why uninsured motorist issues often show up after:
- Rear-end crashes during stop-and-go traffic (where the other driver later cannot produce valid insurance)
- Lane-change or turn collisions at higher-speed intersections
- Late-night or weekend impacts when drivers may be less likely to carry coverage
- Crashes involving uninsured drivers who “promise to handle it later”—then disappear or refuse to pay
In these situations, it’s not unusual for an insurer to argue the crash was not caused the way you remember, or to challenge how your treatment ties back to the wreck. The earlier you lock in evidence and case facts, the stronger your position tends to be.
