How to Navigate Liability, Coverage, and Damages

When you’ve been injured in an accident—whether in the Chicago area or anywhere else in Illinois—it’s important to understand what your claim might be worth. Three core factors typically drive the value of a personal injury case:

  1. Liability – Who’s legally responsible?
  2. Insurance Coverage – Which policies apply, and can you combine or “stack” coverage?
  3. Damages (Injuries) – What is the full extent of your losses?

Think of these as the “three legs of a stool.” If one leg is weak or missing, your potential compensation could drop significantly. Below, we break down each element so you can see how they work together—and why hiring a personal injury attorney is crucial in Illinois.

1. Liability in Illinois: Establishing Fault

Why Liability Matters

Liability is about determining who caused the accident. In Illinois, you must typically show that the other party was negligent, and any percentage of fault you share can reduce your final recovery. This approach is known as modified comparative fault.

How to Prove Liability

Visit the Illinois Department of Transportation to review statewide accident data or learn more about road safety initiatives. This data can sometimes be used to support your claim.

2. Car Insurance Coverage: Maximizing Your Potential Recovery

Why Coverage Matters

Even if liability is crystal clear, your recovery is often limited by available insurance coverage. If your total losses are $50,000 but the at-fault party’s policy caps at $25,000, you might be stuck unless you identify additional coverage options.

Types of Coverage to Explore in Illinois

  1. Liability Insurance – The at-fault driver’s policy is your main target.
  2. Uninsured Motorist (UM) Coverage – Applies if the at-fault driver has no insurance; often included in your own auto policy.
  3. Underinsured Motorist (UIM) Coverage – Kicks in when the at-fault driver’s coverage is insufficient.
  4. Umbrella/Excess Policies – Some individuals or businesses carry extra coverage.
  5. Medical Payments (MedPay) – In Illinois, MedPay is an optional coverage that pays medical expenses up to a set limit.

Stacking Coverage

With the right policies, you may be able to combine or “stack” your UM/UIM coverages. If the at-fault driver was on the job or using a commercial vehicle, their employer’s policy might also apply. An attorney can help find these multiple layers of coverage.

3. Damages: Documenting the Full Scope of Your Injuries

Why Damages Matter

Damages are the economic and non-economic losses you’ve experienced. These may include:

You only get one chance to resolve your personal injury claim. If you accept a quick, lowball settlement or fail to continue needed medical treatment, you risk leaving money on the table. Insurance companies might deny or reduce your claim for future expenses—such as a surgery you need years from now—if it’s not accounted for in the initial settlement.

Coordinating Care

At Postman Law, we help you obtain proper medical treatment and document every aspect of your injury. Whether you’re seeing specialists in Chicago or a local physical therapist in Peoria, thorough medical records build a stronger case. If an insurance company questions your injuries, consistent documentation makes it harder for them to deny or reduce your claim.

How the Three Elements Work Together

All three must align to create a strong personal injury case. Even if fault is undeniable, limited insurance coverage or unverified damages can shrink your final payout.
