How Can Eyewitness Testimony Affect a Personal Injury Lawsuit?

Maybe a stranger told the police officer the other driver ran the red light, then left before you could get their name. Finding that witness could be important to your case. Eyewitness testimony can help or hurt a personal injury lawsuit because it often answers the case's biggest question: who caused the injury, and how much each person is to blame.

There is one catch. A witness only helps if the jury believes them. If their story changes or doesn’t match the physical evidence, it can hurt the side that relies on it. 

At The Law Office of Thomas C. Hall, I help injured people in San Antonio and across South Texas find and protect the witness evidence their cases depend on. If someone saw your crash, fall, or work accident, or if you’re not sure whether anyone did, a free consultation can help you understand what that evidence may mean for you. 

What Can an Eyewitness Say in Court?

An eyewitness can only testify about what they saw, heard, or noticed. The Texas Rules of Evidence require witnesses to have personal knowledge of what they describe. A regular witness, unlike an expert, can share an opinion only if it’s based on what they observed and helps the jury understand what happened. 

For example, a bystander can say the light was red, which way each car was going, or that the other driver was looking at a phone. That witness usually can’t guess what the driver was thinking. They also can’t repeat details someone told them later. 

What a witness heard can sometimes count, too. The rules usually limit secondhand statements, but exceptions exist. One covers statements made in the shock of the moment. Another covers a party’s own words used against them. So if the other driver said, “I never saw you,” while a bystander was nearby, the bystander’s memory of it could become important evidence. 

How Witnesses Affect Who Is at Fault

Witnesses often matter most when both sides share some blame. Texas uses a system called proportionate responsibility. Under it, the jury gives each person a percentage of fault. Your money award is reduced by your share. If you’re found more than 50 percent at fault, you can’t recover anything. 

Here’s how that works in real numbers. If a jury awards $100,000 in damages and finds you 20 percent at fault, you would receive $80,000. Insurance companies know this, so they look for any detail that shifts blame to you. A neutral witness who says you had the green light can shut down that argument. A witness who says you were speeding gives the insurer something to use. 

Even if your case never goes to trial, witnesses still matter. Settlement offers are based on what each side thinks a jury would do, so strong witnesses can lead to better offers. 

What Makes a Witness Believable?

A jury looks at who the witness is, where they were, and whether they have a reason to take sides. That often matters more than how many witnesses you have. In many personal injury cases, one neutral stranger with a clear view can carry more weight than several friends or one driver's passengers. 

Here are some of the things a jury may consider: 

• Connection to the people involved: A stranger is usually harder to doubt than a relative, coworker, or passenger. 

• What they could see: Distance, lighting, weather, and anything blocking the view can affect what the witness could notice. 

• When they spoke up: A statement given to police at the scene often counts more than one given months later. 

• Whether the story stays the same: Under Texas rules, the other side’s lawyer can point out earlier statements that don’t match the witness’s testimony. If details change, the defense will use it. 

What If a Witness Blames You?

A witness who supports the other side doesn’t automatically end your case. Every witness’s story gets tested.

Good questions can uncover gaps, such as whether the witness had a clear view, whether they saw the crash itself or only what happened after, and whether they’re assuming things they didn’t actually see. Physical evidence can also contradict a witness. This can include vehicle damage, skid marks, security or dashcam video, and phone records. 

Even if a witness blames you, you may still recover money as long as you’re not more than 50 percent at fault. One word of caution: don’t contact an unfriendly witness to argue about what they saw. Pressuring someone to change their story can backfire and give the other side new ammunition. 

Why You Should Act Fast to Save Witness Statements

Witness evidence is strongest early, before memories fade and people move away. In Texas, you generally have two years to file a personal injury lawsuit. But most witnesses won’t remember clear details for that long. If you wait, you may end up with only a name and a fuzzy memory. 

If you can, get names and phone numbers at the scene. Check whether the police report lists any witnesses, and write down anything people said while it’s still fresh.

Also note any nearby businesses with cameras. Video is often erased quickly, and it can support or challenge what a witness remembers. After a lawsuit is filed, witnesses can give sworn testimony in a deposition. In a Texas civil case, you can generally use that deposition at trial, which helps if a witness later becomes hard to reach. 

Pursue the Compensation You Deserve After an Injury

Whether a witness helps your claim or creates a problem, it’s best to look at their account as early as possible. I’m a third-generation Texas attorney with more than 30 years of experience helping people. I represent injured clients in San Antonio and throughout South Texas. 

When I take a case, I work to find out who saw what happened. I compare their stories with police reports, photos, video, and the physical evidence. When a lawsuit moves forward, I take depositions to lock in what witnesses say under oath.

If an insurance company uses a witness to shift blame to you, I closely review that witness’s account and challenge its weak spots. And if the insurer won’t offer a fair settlement, I’m ready to present the evidence at trial. 

If you want an honest look at the witness evidence in your case, talk with a San Antonio personal injury lawyer who will go over it with you personally. Contact me to schedule a free consultation, and bring your police report and the names of anyone who saw what happened.
