How We Help in Impaired Driving Cases

We coordinate with prosecutors for access to evidence, obtain crash data and video, and build a clear liability and damages picture. Then we handle the insurers and fight for full recovery for Missouri and Illinois victims and families.

Our Approach

Investigate & Preserve Evidence

Police reports, BAC/toxicology, field tests, bodycam and dashcam, EDR/black box data, 911 audio, and witness statements.

Handle Insurance & Bills

We navigate liability, UM/UIM, med pay, liens, and subrogation so medical care continues while the case proceeds.

Build Full-Value Claims

We document treatment, future care, wage loss, and non-economic harms — and pursue punitive damages where allowed.

Litigate When Needed

If the insurer won’t be fair, we file suit in Missouri or Illinois, use qualified experts, and prepare for trial.

Common Impaired Driving Scenarios

  • DUI/DWI alcohol crashes
  • Drug-impaired (prescription or illegal) driving
  • Mixed impairment (alcohol + drugs)
  • Rear-end and intersection collisions
  • Pedestrian & cyclist impacts
  • Rideshare driver or passenger injuries
  • Commercial driver impairment
  • Uninsured/underinsured motorist claims

Damages You Can Claim

Economic

  • ER/hospital care, surgery, therapy
  • Prescriptions and medical devices
  • Lost wages & diminished earning capacity
  • Vehicle repair/total loss and rental

Non-Economic

  • Pain and suffering
  • Loss of normal life
  • Emotional distress
  • Disfigurement or disability
  • Loss of consortium

Punitive damages may apply in egregious impairment cases.

What to Do After an Impaired Driving Crash

  • Call 911, get medical care, and follow your doctor’s orders.
  • Ask police for the report number; note any field or breath tests.
  • Photograph vehicles, scene, and injuries; save dashcam footage.
  • Do not give recorded statements or broad medical releases to insurers first.
  • Keep bills and receipts; track missed work.
  • Contact a Missouri & Illinois impaired driving attorney quickly.

Insurance Pitfalls

  • Insurers may dispute impairment or causation despite police findings.
  • Quick offers often ignore future care and wage loss.
  • Statements to adjusters can be used against you.
  • UM/UIM may apply if the impaired driver is underinsured.

Missouri & Illinois Basics

Criminal vs. Civil: DUI/DWI charges are separate from your civil claim. A conviction is not required for civil recovery.

Comparative Fault: Recovery is reduced by your share of fault; Illinois bars recovery if more than 50% at fault.

Time Limits: Illinois generally has a 2-year deadline for injury claims; Missouri generally allows up to 5 years. Some evidence (video, data) must be preserved immediately.

Each case is unique — ask our attorney about your Missouri or Illinois crash.
