FAQ

What’s black box data, and how is it used in car accidents?

Black box data includes information like speed, braking, and seatbelt use before crashes. This evidence helps prove exactly what happened, supporting or disproving witness statements and establishing fault.

Do all cars in Michigan have black boxes / EDRs?

All vehicles manufactured after September 1, 2014, must have EDRs. About 96% of new cars include these devices, so your car is likely to have one. 

How long does black box data last?

EDR data can be overwritten within days or after another impact. Contact a car accident lawyer in Michigan immediately so they can send preservation letters preventing vehicle disposal. It’s important to gather this evidence as quickly as possible so it can be used for your case. 

Can insurance companies access black box data without a lawyer?

Insurance companies need owner consent or court orders to access EDR data. Legal representation makes sure they can’t misuse this evidence against you. 

What's the cost of retrieving black box evidence?

EDR extraction often costs several thousand dollars, plus expert witness fees. On contingency, these costs are covered up front and repaid only if we win. 

How do Michigan courts treat black box evidence?

Michigan courts accept properly authenticated EDR data as reliable scientific evidence when presented correctly with expert testimony.
