Common Delays in Chicago Car Accident Investigations and How to Overcome Them

Nov 3, 2025

Reviewed by Nicholas P. Kelly, Esq.

Car accidents in Chicago can create sudden chaos not just on the road, but in the days and weeks that follow. While many victims expect a straightforward process after reporting the crash and seeking medical care, investigations can sometimes stall. These delays can be frustrating and stressful, especially when you need answers and financial relief.

At Wallace Miller, our Illinois car accident attorneys understand how complex these investigations can become. Whether it’s waiting for reports, dealing with insurance companies, or resolving disputes about fault, knowing what causes hold-ups and how to overcome them can make a significant difference in how quickly your case moves forward.

Waiting for the official police report

One of the most common causes of delay in any car accident investigation is the police report. After a crash, the Chicago Police Department or Illinois State Police will respond, gather information, and file an official report. Depending on the severity of the collision and the agency’s workload, the report may take several days or even weeks to become available.

Why it matters:

The police report often includes critical details, such as witness statements, officer observations, and any citations issued. Insurance adjusters and attorneys use this information to help establish liability, which refers to the legal responsibility for causing the crash.

How to overcome it:

Our attorneys can request a preliminary incident number from the responding agency to monitor progress. In the meantime, collect your own documentation, including photographs, witness names, and medical records, so that your claim can begin even before the final report is released.

Insurance investigations and liability disputes

Once the crash is reported, insurance companies open their own investigations. If multiple insurers are involved or the parties disagree on who caused the crash, this process can drag on for months.

Why it matters:

Delays often occur because insurers dispute fault or question the value of your damages, which include medical costs, lost income, and property losses. These disputes can delay settlement offers or result in unnecessary claim denials.

How to overcome it:

Our attorneys can manage communications with all insurers involved, ensuring that they respond in good faith and within required timeframes. The team at Wallace Miller keeps adjusters accountable and prevents companies from using delay tactics to pressure victims into accepting less than they deserve.

Determining fault and collecting critical evidence

In Chicago, fault is rarely as simple as one driver admitting responsibility. Traffic congestion, multiple vehicles, and limited visibility can complicate the determination of what truly happened.

Why it matters:

A fault determination affects the amount of compensation awarded under Illinois law. Under this rule, you can still recover damages if you were partly at fault, as long as your share of responsibility is less than 51 percent.

However, your recovery amount is reduced by your percentage of fault. For example, if you were found 20 percent at fault, your compensation would be reduced by 20 percent.

How to overcome it:

Our attorneys can help secure vital evidence before it disappears, such as surveillance footage, dashcam recordings, and electronic “black box” data from the vehicles involved. This data — formally called an event data recorder — can show details like speed, braking, steering, and seatbelt use in the moments leading up to the crash. Together, these materials help establish an accurate timeline and prevent one-sided narratives from controlling the outcome.

Delays in obtaining medical documentation

Hospitals and medical offices across the Chicago area often require significant time to process medical record requests. When facilities are backlogged, it can delay your ability to document injuries and verify your treatment plan.

Why it matters:

Medical records are a cornerstone of any personal injury claim. They prove the extent of your injuries, connect these injuries directly to the crash, and provide an accurate account of your recovery and prognosis. Without records, it can be difficult to evaluate a claim or calculate fair compensation.

How to overcome it:

Our experienced attorneys can issue formal medical record requests and follow up with healthcare facilities to expedite the process. At Wallace Miller, we routinely work with hospitals and providers across Illinois to ensure your medical documentation is obtained, organized, and ready for use in settlement negotiations or trial.
