Uninsured & Underinsured Motorist Claims for Chicago Motorcyclists: Your Real Lifeline
You watched your lane on the Kennedy, you signaled, you were riding sober and alert. Then a driver blows a light on Ashland, clips your bike, and takes off, or hands you an insurance card for a policy that barely covers a fender. When the driver who wrecked you does not have enough insurance, the coverage that saves you is not theirs. It is yours.
Why UM/UIM Is a Rider's Real Lifeline
Motorcyclists get hurt worse than people in cars. Same crash, far more serious injuries, because you do not have a steel cage, airbags, or crumple zones between you and the pavement. A collision that leaves a sedan driver with a stiff neck can leave a rider with surgeries, months off work, and a totaled bike.
Now do the math on the other side. Illinois only requires drivers to carry 25/50/20 in liability: $25,000 per person for bodily injury, $50,000 per crash, and $20,000 for property damage. That $25,000 does not get a seriously injured rider through the emergency room, let alone follow-up surgery and lost wages. And that assumes the at-fault driver even carried a legal policy. Plenty on Chicago roads do not. UM/UIM is what stands in that gap.
Illinois Requires UM, and You Cannot Waive It
Every auto liability policy issued in the state has to include UM coverage at least equal to the 25/50 bodily-injury minimum, and under Illinois law that UM coverage cannot be waived (625 ILCS 5/7-203; 215 ILCS 5/143a). You cannot accidentally opt out of it. If you carry a legal auto or motorcycle policy in Illinois, you have at least some UM protection built in. That matters in two common Chicago scenarios.
- ✓ Hit-and-run. The driver who ran you off DuSable Lake Shore Drive and vanished counts as uninsured for UM purposes. You do not need to identify them to use your own coverage.
- ✓ The uninsured driver. The person who hit you was breaking the law by driving with no policy. Your UM coverage responds as if they had carried the minimum.
- ✓ UIM picks up where UM stops. Underinsured motorist coverage is required when you buy UM limits above the state minimum, and it does the heavy lifting when the at-fault driver had insurance, just nowhere near enough.
How UIM Stacks When the At-Fault Driver Is Underinsured
UIM does not replace the at-fault driver's coverage. It sits on top of it. Say you carry $250,000 in UIM coverage, and the driver who hit you on the Eisenhower carried only the state-minimum $25,000 in bodily injury. The at-fault driver's insurer pays their $25,000. Your UIM coverage then fills the gap up to your $250,000 limit. Total available to you: $275,000, the $25,000 from them plus up to $250,000 more from your own policy on top. Without UIM, you would be staring at that $25,000 and eating the rest of a six-figure injury yourself.
What Limits Should a Chicago Rider Carry?
Since UM/UIM is your real backstop, the state minimum is not where you want to be. A serious motorcycle injury blows past $25,000 fast. Riders with something to protect should think about 100/300 liability ($100,000 per person, $300,000 per crash), UM/UIM set to match that liability, MedPay of $5,000 to $10,000 that pays medical bills regardless of fault, and an umbrella policy if you own a home or have real assets to shield. Weigh the small monthly cost against how far a $25,000 policy would actually stretch after one bad left-turn crash on Milwaukee Avenue.
Insurers Fight UM/UIM Claims Too, Even Your Own
When you file a UM/UIM claim, you are making a claim against your own insurance company, and they do not roll over just because you have paid your premiums for years. The same playbook applies: adjusters diminish, devalue, and deny. They question whether your injuries are as serious as you say, argue you were partly at fault, or lowball what your claim is worth. UM/UIM claims often go to arbitration, and the insurer will have lawyers. You should too.
