How long is EDR data stored?

Few passenger cars have event data recorders. The insurance companies rarely obtain any readings from EDR except in very severe accidents involving 18-wheelers (that do carry them). The insurance companies never see the EDR.

Do insurance companies check black box?

In modern diesel trucks, EDRs are triggered by electronically sensed problems in the engine (often called faults), or a sudden change in wheel speed. One or more of these conditions may occur because of an accident.


What do EDRs record?

Event data recorders (EDRs), also known as “black boxes” or “sensing and diagnostic modules,” capture information, such as the speed of a vehicle and the use of a safety belt, in the event of a collision to help understand how the vehicle's systems performed.


Do car black boxes track location?

Black box technology uses GPS tracking to monitor the roads you use and the speed limits, but we would never monitor your location in real time unless you ask us to. However, GPS can be beneficial in rare circumstances - if your car is stolen, for example.Apr 6, 2018

What is an EDR and why do you need it?

  • By imaging the data contained on an EDR from a crash, a claims professional can gain a better picture of what occurred. Recently, the National Insurance Crime Bureau (NICB) warned of a rise in parked and unattended vehicle accident fraud. EDR data can be a valuable asset in these claims.


How is the EDR used to verify an insurance claim?

  • In order to verify the claim occurred as reported, the EDR of the insured vehicle is imaged. The EDR image may either support the insureds’ version of events or it will provide proof that the vehicle was in motion or being driven at the time of the accident.


Do EDRs make roads safer?

  • The price of safer roads is thus the risk that private EDR data may be used by insurance companies, the legal system, or other bodies. Currently, EDRs are widely installed and used by vehicle manufacturers, insurance companies, law enforcement agencies, and researchers.


Who is the owner of the data collected from an EDR?

  • Ownership of the EDR and EDR data is a matter of State law, and such provisions vary considerably. NHTSA considers the owner of the vehicle to be the owner of the data collected from an EDR. NHTSA will always ask permission from the owner of a vehicle before downloading any information for use in government databases.
