Uninsured motorist (UM) coverage is designed for situations where the at-fault driver can’t pay because they’re uninsured or their coverage doesn’t meet the policy requirements.
In San Bruno, these situations commonly show up after:
- Commute collisions on high-traffic routes where police reports may be disputed or details get fuzzy quickly.
- Lane-change and rear-end impacts involving drivers who later claim they’re not responsible—or who disappear after the crash.
- Airport-area traffic patterns where multiple vehicles and witnesses are present, but footage can be overwritten or difficult to obtain later.
When the other driver isn’t financially reachable, your UM claim often becomes the primary path to pay for medical treatment, recovery-related costs, and wage losses. The problem is that insurers may still challenge fault, causation, and the seriousness of injuries.
