While expert witnesses are used in car accident cases, not every lawsuit requires one. Many claims can be settled using police reports and photos. Expert witnesses are only necessary when key facts are disputed, but their testimony can influence trial outcomes and insurance claims.
What Is an Expert Witness?
An expert witness is a professional who gives the court an unbiased opinion on a specific topic that is typically outside of the domain of public knowledge. Ordinary witnesses often testify to what they saw or heard. However, expert witnesses can explain data and interpret facts to help the jury decide a case. Expert witnesses are hired by a judge or a party to expand upon the evidence at hand.
The qualifications required to be an expert witness include:
• Education: Advanced degrees like a Ph.D., master’s, or medical degree
• Training: Specialized training
• Experience: Years of active work in a specific field
• Certifications: Board certifications or licenses
• Publications: Published articles, research papers, or peer-reviewed books
Not everyone working in a particular field is qualified to serve as an expert witness. Courts use a variety of methods to determine whether an expert has the necessary qualifications. The judge may hold a pretrial hearing to determine if the person qualifies, perform a relevance check to determine if the person’s knowledge directly fits the case, or apply the Daubert or Frye standard rules.
Expert opinions carry significant weight in court because they provide specialized insight. Rather than relying on emotions or guesswork, expert witnesses base their views on established scientific principles and verifiable facts. They can also help clarify complex cases by connecting the missing dots in medical or technical evidence.
Are Expert Witnesses Required in Every Car Accident Case?
No, expert witnesses are not required in every car accident case. In fact, many car accidents are relatively straightforward and eventually settle out of court.
Expert witnesses are not needed when:
• There is minor vehicular damage and clear liability
• There is minor property damage
• The insurance company accepts fault
• Injury claims are minor and not disputed by either party
On the other hand, expert witnesses become valuable when:
• Insurance companies dispute who is at fault
• Liability is unclear or shared
• There are severe injuries or fatalities
• The accident involves many cars or a commercial vehicle
• Cases don’t settle but proceed to litigation
When Are Expert Witnesses Most Commonly Used?
When an accident is complex, or there are fatalities, it’s important to bring in an expert witness to help the jury understand the evidence. Here are some instances where an expert witness may be especially beneficial:
Catastrophic Injuries
Expert witnesses are usually brought in to explain long-term medical prognoses for catastrophic injuries. They can help juries calculate lifetime financial damages for instances such as partial paralysis, spinal cord injuries, or traumatic brain injuries.
Wrongful Death Cases
Medical experts can help establish the actual cause of death, while accident reconstructionists can analyze the physical data to show how the accident happened.
Commercial Truck Accidents
Because commercial trucks have to abide by complex regulations, truck industry and safety experts are frequently called to testify. They evaluate whether the commercial truck driver complied with the Federal Motor Carrier Safety Administration (FMCSA) regulations and industry standards at the time of the accident.
Multi-Vehicle Collisions
When liability is disputed or is split amongst more than one driver, accident reconstructionists can simulate the crash using the physical data to determine who was at fault.
Motorcycle and Pedestrian Accidents
When accounts of an accident differ, forensic experts and accident reconstructionists are brought in to help establish the truth. They will examine physical data, interpret the facts, and recreate the accident. Physical data includes factors such as glare, line-of-sight obstructions, and skid marks.
Conflicting Witness Testimony
Witnesses to an accident often present conflicting accounts, particularly if the accident was traumatic. In these situations, experts can analyze and interpret dashcam footage, vehicle damage, and impact angles to provide an objective and evidence-based account of the crash.
Defective Vehicle Parts Cases
When a malfunctioning part in a vehicle is suspected of causing a crash, mechanical engineers may be called to testify. Their analysis can be used to determine whether there was a manufacturing flaw and whether the component failed before the accident and not because of it.
Road Conditions Cases
In instances where road conditions caused a vehicle accident, such as a missing stop sign, a pothole, or bad lighting, civil or traffic engineers may be called to testify. Their evaluations can prove that a government entity failed to maintain the road and is therefore liable for the accident.
What Evidence Expert Witnesses Often Review
Expert witnesses often review the following:
• Police accident reports: They interpret officers’ notes, diagrams, and initial fault estimates.
• Crash scene photographs: Accident reconstructionists analyze skid marks and the final resting positions for all vehicles.
• Surveillance or dashcam footage: Real-time video of how the collision happened can be simulated with computer models to determine speed and impact.
• Vehicle damage: The angle of impact and crush patterns can be especially helpful for accident reconstructionists recreating the accident to determine who is at fault.
• Electronic data recorder (“black box”) information: Black box data showing speed, braking, and steering wheel input can be helpful for trucking industry/safety experts to determine if the trucker or vehicle is responsible.
• Medical records: Diagnostic imaging, such as MRIs, X-rays, and CT scans, can show physical injuries caused by the accident.
• Phone records: Experts can analyze texts, calls, and data use logs to show when a driver was distracted.
• Road conditions: Experts can be brought in to show how poor lighting, missing road signs, or poor road conditions contributed to an accident.
Types of Expert Witnesses
Expert witnesses typically differ depending on what a court needs. Here is a breakdown of the different types of expert witnesses:
Accident Reconstruction Experts
Accident reconstruction experts use engineering, physics, and math to recreate collisions. By simulating and reconstructing the accident, they can effectively determine impact points and crush profiles. They also analyze skid marks, road evidence, surveillance footage, and black box data.
Medical Experts
Medical experts explain how the collision caused specific injuries using X-rays, MRIs, and CT scans. By showing how the force of the accident caused the injury, they rule out pre-existing injuries or conditions. They can also discuss future medical needs and long-term recovery schedules. For victims with permanent disabilities, medical experts can demonstrate how those disabilities will impact daily life.
Economic Experts
Economic experts accurately calculate lost wages and reduced earning capacity. They can also project long-term financial losses and evaluate disability-related employment limitations. Economic experts are valuable when a jury must decide the appropriate amount of financial compensation for the victim.
Mental Health Experts
Mental health experts tend to be psychologists, therapists, or licensed clinical social workers who can evaluate the victim’s emotional and psychological trauma, anxiety, PTSD, and depression following the crash. With their specialized training, they can also prove that the accident directly caused the emotional trauma.
Automotive Engineering Experts
Automotive engineering experts can determine if a vehicle defect or manufacturing flaw caused the crash rather than human error. Key areas they analyze include brake failures, tire failures, airbag malfunctions, or mechanical issues.
Human Factors Experts
Human factors experts study human behavior to determine how a vehicle collision happened. Areas they analyze include driver distraction, reaction times, fatigue, and even a driver’s perception – what the driver saw and understood.
How Expert Witnesses Can Strengthen Your Case
If you have a complicated legal case or there is a dispute over who is at fault, an expert witness can significantly strengthen your claim.
Expert witnesses use math and science to show how the crash happened and who is at fault. They can also take complex evidence and explain it in simple terms to a jury and a judge.
For accident victims seeking financial compensation, expert witnesses can also provide exact numbers needed for long-term rehabilitation, medical bills, or even lost wages. And they can often challenge the low numbers that insurance companies provide.
Expert witnesses reduce speculation, too, especially amongst conflicting witness accounts. By proving what really happened with precise simulation models, they can replace wild, inaccurate guesses with evidence-based science.
How Attorneys Choose Expert Witnesses
Relevant experience to the specific case is one of the most important considerations when choosing expert witnesses. Attorneys will usually seek out expert witnesses who have worked on similar cases.
Professional credentials are equally important. Strong candidates have advanced degrees, board certifications, specialized training, or active licenses.
Not every expert can handle a courtroom, though, which is what makes courtroom experience another valuable asset. Courtroom experience often means expert witnesses can better withstand tough questioning by opposing lawyers and will remain composed and professional under pressure.
A reputation for objectivity is crucial, too. Juries can often spot bias quickly, so credible expert witnesses provide an honest analysis that does not favor either side.
Finally, good communication skills are essential. Expert witnesses must be able to answer questions directly, explain complex concepts clearly, and listen well. They must also exude confidence that builds trust with the judge and the jury.
How Expert Witnesses Work During a Car Accident Case
If you’re considering using an expert witness for your vehicle accident case, it’s helpful to understand what the process involves. Here is what you can expect:
• Review evidence: Expert witnesses study the police report, damage data, surveillance footage/photos, and the scene of the accident to determine how the accident happened. If the crash involves a few vehicles, they may need to reconstruct the collision.
• Examine medical records: Medical experts review X-rays, doctor’s notes, MRIs, CT scans, and more to determine if the collision is directly responsible for any injuries.
• Conduct an independent evaluation: They may check car parts, tires, brakes, and even visit the scene of the accident to evaluate the case further.
• Write a report: After performing a thorough evaluation, they put their findings in a written report for both legal teams.
• Provide a deposition: They answer questions under oath before the trial starts.
• Testify during trial: Once the trial begins, they testify in the courtroom to explain their findings to the judge and the jury.
Can Insurance Companies Use Their Own Expert Witnesses?
Yes, insurance companies use their own expert witnesses to challenge liability or to minimize payouts. Here are some expert witnesses that insurance companies use.
Independent medical examinations (IMEs)
Although their title is “independent,” IMEs work for one side: the insurance company. IMEs are physicians who are hired to look for pre-existing injuries or over-treatment, such as whether a specific treatment or surgery was necessary.
Accident Reconstruction Experts
Insurers tend to hire their own accident reconstructionists to shift blame to the plaintiff. They study crash photos, skid marks, black box data, and surveillance footage.
When both sides hire their own expert witnesses, a “battle of the experts” ensues, where both sides present conflicting scientific facts or medical opinions.
In these situations, it’s up to the judge and jury to weigh the different methodologies presented and decide on a fair outcome.
It’s important to remember that expert witnesses present facts and expert opinions on a case, but they do not decide who wins the case. In addition, their opinions must be grounded in accepted principles and scientific evidence. Even then, a judge may choose to challenge or even exclude their testimony.
