Many semi trucks now come equipped with what is know as the "black box." The black box is essentially an electronic data recorder that monitors and reports information when certain things happen.
Not all trucks are equipped with a black box. An experienced truck accident lawyer will know which 18-wheelers have the event recorders and which do not.
It takes a special technician to download the crash data from the black box or event recorder. It's important to hire an experienced truck accident lawyer soon after your accident because the trucking company may try and delete the material before you can gain access to it. The data in the black box can help explain what happened in the accident and give us concrete data to show the insurance company.
If you or a family member has been seriously injured in an 18-wheeler accident, obtaining the black box information can be critical to the success of your case. The driver of the 18-wheeler may try and lie about the wreck, but the black box data will help us recreate the accident and prove what really happened.
