In California, uninsured motorist coverage is meant to step in when the responsible driver lacks adequate coverage. But the UM claim process can still be complicated because insurers often challenge:
- Whether the other driver was truly uninsured under the policy terms
- Whether the crash caused your injuries (especially when symptoms develop over time)
- Whether particular losses are covered under your UM endorsement
If you’re dealing with a crash on a high-traffic route or a collision involving a pedestrian or cyclist, documentation matters even more—because insurers may argue you’re “part of the story” in a way that reduces payout.
