You’re recovering from a car accident, your medical bills are climbing, and the at-fault driver’s insurance maxes out at $15,000. That doesn’t come close to covering your losses. This is exactly when the question hits: what does underinsured motorist coverage pay for, and does your own policy actually protect you? The answer matters more than most drivers realize, and it can mean the difference between full financial recovery and thousands of dollars out of pocket.
At Steven M. Sweat, Personal Injury Lawyers, APC, we’ve spent over 25 years representing accident victims across Los Angeles and throughout California who find themselves in this exact situation. We’ve seen firsthand how underinsured motorist (UIM) coverage works in practice, what it actually pays for, where the gaps are, and how insurance companies try to minimize what they owe. It’s one of the most misunderstood parts of an auto policy, and getting it wrong can be costly.
This article breaks down UIM coverage in plain terms: what expenses it covers, what it doesn’t, how California law applies, and what to do when the at-fault driver’s policy falls short of your actual damages.
