Using a Vehicle’s Black Box to Help Prove Liability for an Austin Car Crash

How a Black Box Works

Austin accidents happen quickly and unexpectedly. The impact of an accident can be so intense and chaotic that soon after, you may find that you do not have a clear idea of how the accident occurred. The other driver may have an entirely different and even contradictory version of the timeline and story, even if you recall what happened. Furthermore, suppose you do not have witnesses that can provide a statement or could not report your account to the police right away. In that case, you may be at risk of losing essential facts and information that can be critical to your car injury case.

If you have been hurt in a car accident and are unclear about what happened, you may be interested in how using a vehicle’s black box can help.

Most importantly, a black box can help you to determine liability for the Austin car crash and hold the other driver responsible for paying the damages and injuries sustained by victims and their families.

How a Black Box Works

A black box is critical to your case as it can help to determine what occurred in the crash. Importantly, the black box can potentially prove fault between you and the other driver in the case.

A black box can show that the other driver was speeding before crashing into your vehicle. In fact, in cases where impaired drivers were speeding, the black box revealed the exact speed at which they were traveling, effectively filling in critical gaps in the facts of what happened.

If you were not fortunate to have witnessed at the scene to recount what happened, then a black box is a great next bet. The major benefit of a black box is that it holds useful information and cannot be altered or tampered with, making the information on it reliable.

Event Data Recorder

Black boxes are also referred to as Event Data Recorders (EDR’s), which hold 15 to 20 seconds of rich information that took place directly before the crash and information that happened 5 to 10 seconds after the crash.

EDR’s can capture the following data:

  • vehicle location and direction vehicle are traveling
  • speed and change in speed after an accident
  • steering wheel performance
  • safety belt status
  • brake performance, including whether the anti-lock brake was activated before the accident
  • duration and force of the crash
  • vehicle roll angle in rollover accidents
  • airbag release and speed
  • ignition attempts following the accident

Black Box Data to Prove Liability

A common way that a black box can help to prove liability is in cases where the parties disagree over how the accident occurred and who is at fault. The data contained in the black box is critical to your case as it can help to assess what happened in a crash and potentially determine fault.

For example, if you have been in a car crash and the other driver is denying they were at fault despite you recalling otherwise, then gap-filling information from a black box will clear up the inconsistent stories regarding what circumstances surrounding the accident.

Multi-Vehicle Crashes

Multi-Vehicle Crashes

In cases where there are multiple cars involved, you can use data contained in the black box can reveal your use of the brakes and even show if you pressed brake performance, including whether the anti-lock brake was activated before the accident, which is made to stop your car from skidding when the driver brakes in a sharp manner. This information would help to prove that you did stop before the car ahead and were hit by a car behind you.


Critical black box information, including the force, speed, and direction of impact, can all contribute to helping to support your injuries and their severity, such as brain or spinal cord injury.
