Key Takeaways
- Usually not. $25,000 is the statutory floor and rarely covers a serious motorcycle injury.
- Your own UM coverage probably equals your liability limits, unless you rejected it in writing.
- Coverage does not add together. UIM pays its limit less what you already recovered.
- Minimum UIM against a minimum driver pays nothing, because their vehicle is not “underinsured” as defined.
- Check your declarations page today, not after a crash.
What the other driver is required to carry
Illinois sets minimum liability limits in 625 ILCS 5/7-203. For a policy to satisfy the requirement it must provide not less than:
| Cover | Minimum |
|---|---|
| Bodily injury or death, any one person | $25,000 |
| Bodily injury or death, two or more persons | $50,000 |
| Injury to or destruction of property | $20,000 |
These are minimums, not typical limits. Plenty of drivers carry far more. But a rider has no way of knowing which kind of driver hit them until the policy is disclosed, and a serious motorcycle injury can exhaust $25,000 before the first surgery is finished.

The coverage you may not know you have
This is the part most riders get wrong, and it is usually good news.
Under 215 ILCS 5/143a-2(1), an Illinois policy must include uninsured motorist coverage in an amount equal to the insured’s bodily injury liability limits, unless the insured has specifically rejected the excess in writing.
Read that again with your own policy in mind. If you carry $250,000 of bodily injury liability, your uninsured motorist coverage is $250,000 as well, unless at some point you signed a written request for less. You do not have to have bought it as a separate product; the statute puts it there by default.
Two details matter:
- Rejection must be written, and under 143a-2(2) it is binding on all persons insured under the policy, not only the person who signed.
- Underinsured coverage follows. Under 143a-2(4), UIM must be included equal to the total UM coverage in the policy where that exceeds the statutory minimum.
Why the cover does not add up
Riders often assume that if the at-fault driver has $25,000 and they hold $100,000 of underinsured cover, the total available is $125,000. It is not.
215 ILCS 5/143a-2(4) provides that the UIM insurer’s limit is the limit of that coverage less those amounts actually recovered under the at-fault policy. So:
- At-fault driver pays $25,000.
- Your UIM limit is $100,000.
- Your UIM insurer pays $75,000, being $100,000 less the $25,000 recovered.
- Total: $100,000, not $125,000.
Your own limit is the ceiling on the whole recovery from insurance, not a sum added on top of theirs.
The trap in carrying the minimum
This follows directly from the definition, and it is the most consequential thing in this article.
Under 143a-2(4), an “underinsured motor vehicle” means one whose applicable bodily injury limits total less than the limits of your own underinsured coverage.
Now apply it. If you carry the statutory minimum of $25,000 in UIM, and the driver who hit you also carries $25,000, their vehicle is not underinsured. Their limits are not less than yours; they are equal to yours. There is no UIM claim to make.
Minimum UIM gives you no protection at all against a minimum-limits driver, which is precisely the driver you most need protection from. UIM only begins to do work once your own limits sit above theirs. Raising your own UM and UIM limits is generally inexpensive, and for a motorcyclist it is the single most useful insurance decision available.
Where else money can come from
- Other defendants. An employer where the driver was working, or a vehicle owner. See multi-vehicle crash claims for how apportionment works.
- A public body, where the roadway contributed. That shortens the deadline to one year under 745 ILCS 10/8-101(a).
- Your own medical payments cover, if the policy includes it.
- Umbrella policies, either the at-fault driver’s or your own.
How a UM or UIM claim is decided
Worth knowing before you need it: under 215 ILCS 5/143a, policies must provide that disputes about coverage and the amount of damages are submitted to arbitration before the American Arbitration Association, subject to its rules, with separate provision for medical opinions. A claim against your own insurer is not simply a lawsuit.
The same section also prevents stacking: limits for one vehicle may not be aggregated with similar coverage on your other vehicles to raise the total available to one person in one crash.
அடிக்கடி கேட்கப்படும் கேள்விகள்
Is $25,000 enough after a motorcycle crash in Illinois?
Usually not. $25,000 is the statutory minimum for bodily injury to one person under 625 ILCS 5/7-203, not a typical limit. A serious motorcycle injury involving surgery, hospital care and time off work commonly exceeds it well before treatment is finished.
What are the minimum insurance limits in Illinois?
Under 625 ILCS 5/7-203, not less than $25,000 for bodily injury or death of any one person, $50,000 for two or more persons in one crash, and $20,000 for injury to or destruction of property.
How much uninsured motorist coverage do I have?
Probably as much as your bodily injury liability limits. Under 215 ILCS 5/143a-2(1) an Illinois policy must include uninsured motorist coverage equal to the insured’s bodily injury liability limits unless the insured specifically rejected the excess in writing. Many riders hold more than they realize.
Do my limits and the other driver’s limits add together?
No. Under 215 ILCS 5/143a-2(4) the underinsured motorist insurer’s limit is its coverage limit less the amounts actually recovered under the at-fault policy. With $100,000 of UIM and $25,000 recovered from the at-fault driver, your insurer pays $75,000, for a total of $100,000 rather than $125,000.
If I carry minimum UIM, am I protected against a minimum-limits driver?
No. 215 ILCS 5/143a-2(4) defines an underinsured motor vehicle as one whose applicable bodily injury limits are less than your underinsured coverage limits. If you both carry $25,000, their vehicle is not underinsured and there is no UIM claim. UIM only assists once your own limits exceed theirs.
Can I stack the coverage on my other vehicles?
No. 215 ILCS 5/143a provides that limits for any coverage on one vehicle may not be aggregated with similar coverage applying to other motor vehicles when determining the total insurance available for bodily injury or death suffered by a person in any one crash.
