Why Are Witnesses Important After an Accident?

In some crashes, a driver may never see the other vehicle until the moment of impact.

That is one reason independent witnesses can be important after an accident.

A witness may have seen the collision from a different position and noticed something the drivers did not. Witnesses may provide information about vehicle movements, traffic signals, road conditions, or what happened immediately before or after the crash.

A witness statement does not automatically prove who caused an accident. However, it can provide another piece of evidence that investigators can compare with photographs, vehicle damage, video, crash reports, and other available information.

What Is an Accident Witness?

An accident witness is generally someone who saw or heard something related to a collision.

A witness does not necessarily have to see every second of the crash to have useful information.

For example, one person may have seen the vehicles immediately before impact. Another person may have seen only the collision itself. Someone else may have arrived moments afterward and observed where the vehicles stopped or what conditions were like at the scene.

Potential witnesses could include:

• Other drivers
• Passengers
• Pedestrians
• Nearby residents
• Employees of nearby businesses
• People working near the roadway
• Others who observed relevant events

What matters is what the person actually observed.

What Can a Witness See?

Witnesses may notice details that the people directly involved in the collision miss.

Depending on the circumstances, a witness might have information about:

• Which direction vehicles were traveling
• Whether a vehicle changed lanes
• A traffic signal
• A stop sign
• Vehicle movements before impact
• Where the collision occurred
• Road or traffic conditions
• Events immediately after the crash

A witness may also have a different viewing angle from either driver.

For example, two vehicles involved in an intersection accident may each have a limited view of the other. A person waiting at another part of the intersection might have been able to see both vehicles.

That different perspective can sometimes help investigators understand the sequence of events.

Why Can Independent Witnesses Be Important?

An independent witness is generally someone who does not have an obvious personal interest in the outcome of the accident.

For example, a person driving behind the vehicles who does not know either driver may be able to provide an outside account of what happened.

That does not mean an independent witness is automatically correct.

People can make mistakes. A witness may only see part of an event, misremember a detail, or have an obstructed view.

Instead of assuming that any one witness has the complete answer, investigators can compare the person's statement with other evidence.

If a witness's description is consistent with video, physical evidence, and vehicle damage, that consistency may help investigators understand what occurred.

Why Should You Get a Witness's Contact Information?

Witnesses may leave the accident scene before police finish their investigation.

Some may leave before law enforcement even arrives.

If someone tells you that they saw the accident and it is safe to speak with them, getting basic contact information may make it possible to reach them later.

Useful information can include:

• Full name
• Phone number
• Email address, if available

You do not need to conduct a detailed investigation at the roadside.

The important thing is preserving a way to identify and contact the person later.

Without contact information, finding a witness again can become difficult, especially if the person was simply passing through the area.

Should You Ask a Witness What Happened?

If circumstances allow, you can listen to what a witness says they observed.

However, it is important not to pressure the person or try to influence their account.

Questions should not suggest what the answer should be.

For example, there is an important difference between asking, "What did you see?" and telling someone, "You saw that driver run the red light, right?"

A witness's own recollection is more useful when it comes from what the person actually remembers rather than information suggested by someone else.

Investigators may later ask more detailed questions about where the witness was located, what the person could see, and what happened before and after the collision.

What If Witnesses Remember Things Differently?

Witness accounts do not always match.

Two people can watch the same event and remember certain details differently.

One witness might have been watching the traffic signal while another was focused on the vehicles. Their viewing angles may have been different. One person's view may also have been partially blocked.

Conflicting witness statements do not automatically mean someone is lying.

Investigators can compare each account with other evidence, including:

• Photographs
• Video
• Vehicle damage
• Physical evidence
• Crash reports
• Electronic vehicle information
• Roadway evidence

The goal is to determine which details are supported by the overall evidence.

Can a Witness Determine Who Was at Fault?

A witness can describe what they observed, but that does not necessarily mean the witness determines legal responsibility.

For example, a witness might say that they saw one vehicle enter an intersection before another. That observation could be important.

But determining responsibility may require additional information about traffic controls, vehicle movements, roadway rules, video, physical evidence, and other circumstances.

A witness may also give an opinion about who they believe caused the accident. Investigators should distinguish between what the person actually observed and the person's personal conclusion about responsibility.

Can Nearby Businesses Have Witnesses or Video?

Sometimes.

An accident near a gas station, restaurant, store, apartment complex, or other business may have been seen by employees, customers, residents, or other people in the area.

Nearby locations may also have surveillance cameras.

A person who did not directly witness the collision may still help identify whether a camera captured the roadway.

Video availability varies, and recordings may not be kept indefinitely.

This is another reason identifying nearby businesses and potential sources of evidence shortly after an accident can be useful.

What If There Were No Witnesses?

Not every accident has an independent eyewitness.

A lack of witnesses does not mean the accident cannot be investigated.

Other evidence may help explain what happened, including:

• Vehicle damage
• Accident-scene photographs
• Dashcam footage
• Surveillance video
• Police information
• Electronic vehicle data
• Roadway evidence
• Driver statements

In a commercial truck accident, additional records such as ELD information, dashcam video, GPS data, dispatch communications, and electronic truck data may also be available depending on the circumstances.

Witnesses are one possible source of evidence, not the only source.

Why Does It Matter After an Accident?

Witnesses can become harder to locate as time passes. A person who stops briefly at an accident scene may continue driving and never have another connection to the people involved.

Preserving a witness's name and contact information can allow investigators to follow up later.

At Jacqueline A. Scott & Associates, when we investigate a Louisiana car or truck accident, we can speak with available witnesses and compare their accounts with the other evidence surrounding the collision.

We may compare what a witness remembers with photographs, video, vehicle damage, crash reports, electronic information, and physical evidence from the scene.

If different witnesses give different accounts, we do not automatically assume one person is being dishonest. We can examine each person's perspective and determine how their observations fit with the rest of the evidence.

Witness information can help us build a more complete picture of what happened rather than relying only on the accounts of the drivers involved.
