Modern vehicles contain technology that can record important information about what happens during a crash. Often called a car’s “black box,” an event data recorder (EDR) can provide information about a vehicle’s speed, braking, seat belt use, airbag deployment, and other crash-related factors.
This information can be particularly valuable when the drivers involved in a collision disagree about what happened. EDR data may help investigators reconstruct the moments leading up to a crash and determine whether the available evidence supports one driver’s version of events.
If you were injured in a car accident in Chicago or elsewhere in Illinois, understanding what the vehicle’s EDR may show can help you understand why this evidence may matter to your personal injury claim.
A car’s “black box” is commonly known as an event data recorder, or EDR. It is an electronic system that can record certain information related to a crash.
EDRs are installed in many modern passenger vehicles. The specific information recorded can vary considerably among manufacturers and vehicle models. NHTSA explains that EDR systems can provide useful information for understanding crashes, but there are significant differences in what different vehicles record.
An EDR generally becomes relevant when the vehicle experiences a qualifying event. Depending on the vehicle and circumstances, the system may capture information from the period immediately before, during, and after a crash.
The exact information available depends on the vehicle’s manufacturer, model, year, and electronic systems. Some of the crash-related information that may be available includes:
Not every EDR records all of these data points, and the amount of information available can vary between vehicles.
This is one reason EDR evidence should be interpreted by someone who understands the particular vehicle and the data it produces. NHTSA notes that manufacturers have historically differed in the types and extent of information their EDR systems record.
EDR data can provide important evidence about how a crash occurred, but it does not automatically determine legal fault.
For example, EDR data may provide information about:
That information can help establish what a vehicle was doing immediately before and during a collision.
But determining liability may require answering additional questions. Was another driver speeding? Did someone fail to yield? Did a driver cross the center line? Was a traffic signal violated? Did road conditions contribute to the crash? Was another vehicle involved?
EDR information may help answer some of these questions, but it generally needs to be evaluated with the rest of the available evidence.
EDR information can become particularly valuable when the circumstances of a crash are disputed. Suppose two drivers provide different accounts of a collision. One claims they were traveling at the speed limit and had the right of way. The other says the first driver was speeding and failed to stop.
Investigators may be able to examine EDR information from one or both vehicles and compare it with:
The goal is to determine whether the available evidence supports a particular explanation of how the crash occurred.
In a serious Illinois car accident case, this type of evidence can help establish liability and challenge an insurance company’s version of events.
An insurance company may seek access to EDR information when investigating a crash. The process for obtaining and interpreting the data can depend on the vehicle and circumstances.
EDR information generally requires specialized equipment and knowledge to retrieve and interpret. NHTSA notes that many systems use manufacturer-specific technology and that the information recorded can vary among manufacturers.
If an insurance company asks for access to your vehicle’s electronic data after a serious accident, you should understand what information it is seeking and how that information may be used before agreeing to provide access.
Potentially. Like other forms of evidence, EDR data may be relevant when determining how a collision occurred and who may be responsible for the resulting injuries.
Its usefulness will depend on factors such as:
The fact that a vehicle has an EDR does not mean that the data will automatically resolve a dispute. Instead, it can become one part of a broader accident investigation.
If another driver caused your accident, you may not have physical access to that vehicle or its EDR data. That does not necessarily mean the information cannot become part of an investigation.
Depending on the circumstances, an attorney may be able to take steps to identify, preserve, and obtain relevant vehicle data. This can become particularly important when a crash involves serious injuries, disputed liability, or a vehicle that may be repaired, sold, or otherwise altered after the accident.
Preserving electronic evidence early can help prevent potentially relevant information from becoming unavailable.
Vehicle evidence can become more difficult to obtain over time. A damaged vehicle may be repaired, sold, salvaged, or otherwise transferred after a crash. Electronic information may also be affected by subsequent events or repairs.
If EDR information could be relevant to a serious injury claim, identifying and preserving that evidence early can be important.
This is especially true when:
A prompt investigation can help identify what electronic and physical evidence exists before it becomes more difficult to obtain.
A serious car accident can leave you dealing with medical treatment, lost income, vehicle damage, and an insurance company while you are still trying to recover.
Staver Accident Injury Lawyers can investigate the circumstances of your crash and identify evidence that may help establish liability. Depending on the facts, that investigation may include EDR data, photographs, surveillance footage, witness statements, vehicle damage, medical records, and expert analysis.

The goal is not simply to obtain a black box report. It is to understand what the available evidence shows about how the crash happened and how it caused your injuries.
Many modern vehicles have event data recorders, but the presence and capabilities of an EDR can vary by vehicle. The information recorded also differs among manufacturers and models.
There is no single recording period that applies to every vehicle. EDR systems are designed to capture specific crash-related information, and the amount and type of data recorded vary by manufacturer and vehicle. A car’s EDR should not be thought of as a device that continuously stores an unlimited history of everything the driver has done.
An EDR is not generally a recording of conversations inside the vehicle. It is designed to capture specified vehicle and crash-related information, and the information available depends on the vehicle’s systems.
Potentially. Some EDR systems can provide vehicle speed information associated with a crash. Investigators can compare that information with other evidence to help determine how the collision occurred.
Potentially. Depending on the vehicle, EDR data may include information about brake application prior to a crash. That information can be useful when drivers provide conflicting accounts of whether they attempted to stop.
Potentially. EDR information may be considered by an insurer when investigating a collision. Because electronic data can support or undermine different versions of what happened, you should understand what information is being requested and how it may affect your claim before providing access.
If you were seriously injured or the fault is disputed, EDR data may be worth investigating. A personal injury lawyer can determine whether the information could be relevant to your claim and help identify steps to preserve and obtain available evidence.
A car’s black box can provide information that may not be available from photographs or witness statements alone. Speed, braking, seat belt status, airbag deployment, and other crash-related information may help investigators understand what happened in the moments surrounding a collision.
