Would my trucking accident attorney use expert witnesses to prove fault in my big rig accident?

In many cases involving an accident with an 18-wheeler, it is well advised to bring on expert witnesses to help with the accident investigation. They have the ability to sift through and analyze information garnered at an accident scene to determine liability and thus be in a position to provide testimony in court relating to the question of liability. Experts are also often retained to ensure driving logs and safety inspections were done in accordance with the law.
