The accident is not your fault, the other driver clearly caused it — and then you find out they have no insurance. UM/UIM coverage is what determines what happens next.
The accident is not your fault. The other driver is clearly at fault. You exchange information, call your agent — and then find out the other driver has no insurance, or has minimum limits that barely cover a fraction of your medical bills and vehicle damage.
This scenario is not unusual. A meaningful portion of drivers on the road carry no insurance or carry only the minimum limits required by state law. For someone with real injuries, those minimums can be exhausted in a single emergency room visit. Without uninsured and underinsured motorist coverage, what you recover in this situation is limited to whatever the at-fault driver can actually pay — which in many cases is very little.
What UM/UIM Coverage Does
Uninsured motorist coverage (UM) pays when the at-fault driver has no insurance at all. Underinsured motorist coverage (UIM) pays when the at-fault driver has insurance, but their limits are too low to cover your actual damages. In both cases, your own policy steps in — your injuries, lost wages, and in many states your vehicle damage, can be covered up to the limits you chose, regardless of what the person who caused the accident carried.
UM/UIM is one of the few coverages on an auto policy that protects you directly from other drivers' choices. Liability coverage protects others from you. Collision covers your vehicle. UM/UIM covers you from the gap other people create.
Why Clients Often Undervalue It
UM/UIM tends to get cut when clients are looking to lower premiums. It feels like a redundancy — you already have health insurance, you already have collision. The reasoning is that the overlap covers it.
It does not. Health insurance carries deductibles, copays, and network limitations that do not account for a serious injury in the way a liability claim would. Collision covers the vehicle but not the people inside. Neither replaces lost wages or addresses pain and suffering. UM/UIM limits should generally match the liability limits a client carries — if you are willing to pay that amount to protect others from your mistakes, the same logic applies to protecting yourself from theirs.
The Conversation
Do you know what your UM/UIM limits are, and do you know what they would cover if someone hit you and had no insurance? Most clients have never thought about it in those terms. The question makes the coverage concrete — not an abstract policy line item, but a specific scenario they can picture.
For clients who have already been hit by an uninsured driver, the answer is usually immediate. For clients who have not, the conversation is often what prompts them to actually look at their limits — and in many cases, to raise them.
