What is crash data retrieval (CDR)?

Crash data retrieval is a method used to gather information about a traffic accident. It consists of the downloading and analysis of data stored in the event data recorder of a vehicle's airbag module, sometimes called an Airbag Control Module or Restraint Control Module.

What are event data recorders (EDRs)?

Event Data Recorders (EDRs) are electronic devices, commonly called Black Boxes, that are installed in motor vehicles. EDRs have the ability to record information about what a vehicle did before, during and immediately after a traffic crash. EDRs are generally part of a vehicle’s airbag control module, powertrain control module, or rollover sensor.

Do all vehicles have event data recorders?

No. However, the majority of vehicles currently manufactured have some type of EDR installed in them. The National Highway Traffic Safety Administration (NHTSA) estimated that by 2010, at least 85 % of all vehicles manufactured would have EDRs.

Do all event data recorders store the same information?

No. Currently, the circumstances under which an EDR records and the type of data recorded is dependent upon the year, make, and model of the vehicle. An EDR can be configured to record a variety of data including, but not limited to, information about how a vehicle’s airbag and restraint system functioned as well as pre-crash speed, brake use or throttle application.

Can event data recorders (EDRs) record information if the vehicle is turned off?

No. EDRs can only record when power is applied. Powering of the EDR requires that battery power is available and the ignition is in the “on” position.

What vehicles can currently be downloaded?

General Motors, Ford, and Daimler Chrysler EDR data can be accessed through a Crash Data Retrieval (CDR) system manufactured by BOSCH Diagnostics. A select number of Mitsubishi, Isuzu, Suzuki, and Sterling Trucks are also covered. Other EDRs are only accessible through the manufacturers. For vehicle coverage lists, click here.

Will event data recorders ever become standardized?

Yes. NHTSA has released a ruling (NHTSA-2006-25666; 49 CFR Part 563 Titled: Event Data Recorders) that will regulate the type of information that is recorded and the method in which it is stored. The ruling will affect all vehicles manufactured for North America after September 1st 2012 and will require that all manufacturers make their EDR data available to the public. Learn more about NHTSA’s ruling

Who owns the information contained within an event data recorder?

Generally, the data contained within an EDR should be treated as property of the vehicle owner. If consent to access the information from an EDR is being sought, then the vehicle owner should be contacted.

Do any states have event data recorder laws?

Yes. There are currently 13 states with EDR laws. Arkansas, California, Colorado, Connecticut, Maine, New Hampshire, New York, Nevada, North Dakota, Oregon, Texas, Virginia and Washington all have laws governing EDRs. Many more states are expected to draft legislation in the next few years. To read the actual state EDR laws, click here.

Who can benefit from accident investigation and crash data retrieval?

Almost anyone who has been in an accident. This includes drivers or passengers who sustained property loss or injury during a crash. Crash data retrieval and accident reconstruction can also benefit legal counsel (both civil and criminal), insurance companies, car rental agencies and municipalities or government agencies.

What is the difference between accident investigation and accident reconstruction?

Accident investigation is a series of technical methods used to gather information and data about a traffic accident. Accident reconstruction is the analysis of that information and data to accurately explain what happened just prior to, during and just after an accident.

What determines who is responsible in an automobile accident?

Figuring out who is at fault in a traffic accident is a matter of identifying the driver(s) that acted carelessly, or even recklessly. The Illinois Vehicle Code (IVC) dictates how drivers are to operate their vehicles on the roadway. The IVC also applies to motorcycles, bicycles and pedestrians. Sometimes a violation of the IVC is obvious and is clearly defined as the cause of the accident. For example, when one driver runs a red light and crashes into another. In other situations, a violation of the IVC is less obvious. Crash Data Services, LLC has proficient knowledge of the IVC and can help identify the cause(s) of an accident with our services.

Why is crash data retrieval (CDR) useful during accident investigation?

Certified CDR technicians/analysts can apply crash data retrieval to objectively evaluate and describe the events prior to, during and immediately after a crash. The technique is accurate and precise, often supplying information that would otherwise be completely unobtainable with traditional investigative measures.

Why hire an expert accident reconstructionist from Crash Data Services, LLC?

Our experts are often retained for the purpose of identifying the causation and contributing factors in different types of collisions, including the role of the driver(s), vehicle(s), and roadway conditions. We employ peer reviewed and validated methodologies based on the laws of physics, such as the conservation of linear momentum, work-energy methods, and occupant kinematics to explain traffic crashes. Our reports, while technical in nature, are written in a clear and concise fashion. For case specific questions, please contact us.

Is event data recorder information admissible in court?

Yes. Regardless of state, EDR data has been consistently accepted in criminal prosecutions and civil litigation. In many states, including Illinois, EDR data has been tested and found to meet the Frye standard for admissibility (Illinois App. Ct., 4th Dist., No. 4-01-0237, Appeal from Circuit Court of Woodford County, Case No. 98L21 - 2002).

Do any event data recorders store the date, time, or location of an accident?

No. While many vehicles have the ability to monitor the date, time and their location through onboard navigation systems or global positioning systems, no EDRs are currently configured to record that information in the event of an accident.
