Event data recorders were introduced to American open-wheel championship [[Championship Auto Racing Teams|CART]] in the [[1993 IndyCar season|1993 season]],<ref name=indyrec>{{cite web|title=Indy race cars are equipped with Crash Data Recorders to improve safety|url=http://www.nhtsa.gov/DOT/NHTSA/NRD/Articles/EDR/PDF/Research/Indy_race_cars_are_equipped_with_CRASH_DATA_RECORDERS-safety.pdf|website=NHTSA|publisher=Instrumented Sensor Technology, Inc.|access-date=19 June 2017|date=7 August 2001}}</ref> and the [[Formula One]] World Championship in 1997.<ref name=f1rec>[http://papers.sae.org/2000-01-3551/ The Analysis of Accident Data Recorder (ADR) Data in Formula 1] - Peter G.

In North America, EDRs are not mandated on new vehicles, however, if they are installed, they must meet US DOT requirements governing the data they collect,.<ref name="CFREDR"/> however in the EU EDRs are required to be fitted to all new vehicles and the data from such vehicles must be accesible to law enforcement<ref>{{Cite web |date=2024-07-09 |title=Event data recorder (EDR) now fitted to every new car |url=https://www.drivenforensics.co.uk/event-data-recorder-edr-now-fitted-to-every-new-car |access-date=2024-11-24 |website=www.drivenforensics.co.uk |language=en}}</ref> As of 2004, an estimated 40 million passenger vehicles are equipped with the devices.<ref name="TRB-report" /><ref name="usatoday-blackbox" />

In the UK many police and emergency service vehicles are fitted with a more accurate and detailed version that is produced by one of several independent companies. Both the Metropolitan police and the City of London police are long-term users of EDRs and have used the data recovered after an incident to convict both police officers and members of the public.

Line 84:

Another 11% of model year 2016 and newer vehicles are supported by other EDR tools. The limited need to cover less commonly supported vehicles may make the initial investment in software and equipment unnecessary for many in the accident reconstruction or related industries.{{citation needed|date=July 2017}}

=== Crash Scan ===

[https://www.collision-sciences.com/ Collision Sciences] produce a commercially available tool called Crash Scan. The tool works similarly to the Bosch CDR tool (as described above), allowing users to image a vehicles event data recorder. The device is available worldwide and provides access to a wide range of vehicles.

==Information EDR can provide==

The information an event data recorder (EDR) provides varies from vehicle to vehicle. Whilst there are some standard information sets, manufacturers may include additional information. This may include<ref>{{Cite web |date=2024-07-09 |title=What does event data record? |url=https://www.drivenforensics.co.uk/what-does-event-data-record |access-date=2024-11-24 |website=www.drivenforensics.co.uk |language=en}}</ref>:

* Vehicle speed,

* Engine speed,

* Whether the brake pedal and/or accelerator were being depressed,

* Angle of the steering wheel,

* Whether seatbelts were being worn (and sometimes a profile of the person wearing it),

* Forces involved.
