In practice, UM coverage generally becomes relevant when the at-fault driver:
- has no insurance,
- can’t provide coverage that applies to your crash, or
- is otherwise unable to pay in a way that meets policy requirements.
Because California insurance rules and claim-handling standards can affect how coverage is applied, the details of your policy matter. A common Indio problem we see is that people assume UM will cover “everything,” then the insurer narrows the dispute—arguing about the crash facts, injury causation, or whether particular losses are supported.
