Expert Witnesses and the Role They Play in Your Personal Injury Claim

Sometimes, in a personal injury case, general witnesses may be called upon to help provide clarity on some issues that may have been contested. However, in other cases, expert witnesses are called in because they have technical or scientific knowledge regarding a particular area that may prove valuable to the case.

Types of Expert Witnesses


Let's take a closer look at some of the different types of expert witnesses you may come across during an auto accident claim.

Car Accident Reconstructionist


These experts may be consulted for a collision analysis. They work on reconstructing the accident and provide reports that focus on collision speed and vehicle safety. They can testify regarding the amount of acceleration during the accident, the person who had the right of way, braking and steering angles, and other issues that related to the auto accident in question.

DOT Regulations Specialist


Department of Transportation (DOT) regulations experts make sure that helmets, tires, airbags, and other safety features of a vehicle were in proper working condition and tested for safety before they were put on the market. Their expert testimony provides plausible opinions as to whether DOT regulations were followed and how the car accident may have occurred.

First Responders


These experts include police officers, firefighters, and EMTs who are witnesses and can testify to the facts of the case. They often have specialized knowledge that ordinary witnesses to the accident do not. As long as the judge agrees that the first responder is qualified, they will be able to testify.

Medical Doctors


When medical doctors are called for expert testimony in a case, they review all of the facts regarding the case so they can gain a more objective and clear understanding of all the circumstances. They understand medical issues and can clarify if there are any questions regarding such.

How Expert Witnesses Can Help


Lay witnesses are not considered experts and are instead just individuals who saw the accident take place. They can offer a witness statement and testify about:

• The speed and direction of the vehicles involved
• The weather and traffic conditions during the accident
• Lane markings
• Visibility conditions
• Other observations made at the scene

If the case is being disputed for liability, then their testimony can help prove who was at fault for the accident.

The testimony of an expert, even though they didn't witness the accident, is still essential. They have specialized knowledge, training, education, and experience on the subject matter at hand, so they can help back up specific claims.

Your personal injury attorney can call on the testimony of expert witnesses in your case ahead of the trial date so that they can be qualified as an expert in court. Their testimony is especially important to help draw conclusions on how the accident happened. Expert witnesses can also develop models to present in court, including physical and computer models depicting the accident.

If you have been involved in an accident and want to have someone represent you and walk you through the process, you will want to consider hiring a reputable and knowledgeable personal injury attorney. They can help you gather expert witnesses to testify and help prove liability in the car accident.
