An Accident Changes the Landscape. It Doesn't Change the State's Burden.

A DWI arrest involving an accident is a different situation from a routine traffic stop case or welfare check.

When a collision is involved in a DWI, the criminal case rarely exists in isolation. There are damaged vehicles, insurance claims, civil exposure, injured parties, and in many situations, prosecutors who approach negotiations differently than they would in a standard DWI. Understanding how these pieces fit together is part of building an effective defense.

At Denuna & Westbrook, PLLC, we represent individuals facing DWI charges involving accidents throughout Houston and the Gulf Coast region. We’ve handled accident cases at every level, from minor fender-benders with no injuries to serious collisions with significant injuries.

Regardless of the Charge, the State Has to Prove Intoxication

An accident doesn’t change what the State must prove. In every DWI case, even one involving a collision or crash, prosecutors must prove that a person operated a motor vehicle in a public place while intoxicated.

What changes is the context. Officers arrive after the accident rather than observing any driving. They piece together the investigation from witness statements, vehicle positions, physical evidence, and the circumstances at the scene. Assumptions about fault and intoxication develop quickly, and those assumptions aren’t always supported by the evidence.

How an Accident Affects Plea Negotiations

This is where accident cases diverge from routine DWI prosecutions.

When there’s an accident involving property damage or injuries, prosecutors evaluate the case differently. Restitution becomes part of the conversation, and obtaining a favorable outcome is more complicated. Injured parties may have expectations. Insurance companies may be involved. In many cases, the State wants to see financial accountability addressed before agreeing to diversion programs, reduced charges, or other favorable resolutions.

That doesn’t mean favorable resolutions aren’t available. It means the path to get there is more difficult, and additional factors have to be managed simultaneously. A defense strategy in an accident case must account for criminal exposure, civil exposure, and the practical realities created by the accident, not just what happens in the courtroom.

An Accident and Nondisclosure Eligibility

Texas allows nondisclosure relief for certain first-time DWI convictions under the Second Chance Law. But a DWI involving an accident involving another person is generally not eligible, even when the BAC was below 0.15 and no one was seriously injured. A conviction that might otherwise qualify for nondisclosure becomes permanently visible on future background checks.

That distinction is important when evaluating how to resolve the case. A plea that closes the criminal matter quickly may foreclose record-sealing options that would otherwise remain available.

Bond Conditions Become Stricter When an Accident Occurs

Courts view accident cases differently from the start, and that shows up in bond conditions. Even when the BAC is below 0.15 and there’s no prior criminal history, some courts may still impose stricter conditions if a collision occurred. Depending on the court, these conditions may include:

• Ignition interlock device requirements
• Alcohol monitoring
• Travel restrictions
• Reporting obligations

Bond practices vary across Texas courts. Knowing what to expect at the outset helps avoid violations that could jeopardize the case and available options.

When an Accident Leads to a Felony Charge

Many accident-related DWI cases remain misdemeanor prosecutions. Property damage alone doesn’t elevate the charge.

However, when another person suffers serious bodily injury, the allegation may become Intoxication Assault, a Third-Degree Felony requiring the State to prove intoxication caused both the accident and the injury. When a fatality occurs, the charge will likely become Intoxication Manslaughter, a Second-Degree Felony with a punishment range of two to twenty years.

Those are fundamentally different cases with additional elements to prove and a higher evidentiary burden. Unlike a misdemeanor DWI involving an accident where nobody was seriously injured, a felony DWI involves issues of causation, accident reconstruction, and medical evidence. The State’s burden is different, and so is the defense.

Chemical Testing After an Accident

Testing in accident cases may occur in a hospital rather than a jail, and that creates its own set of complications and issues.

Blood may be drawn for medical purposes before law enforcement even makes a formal request. Chain of custody, preservation procedures, the purpose for which the sample was originally collected, and whether it satisfies the requirements for criminal prosecution all become relevant. A hospital blood draw may not be admissible without examination of how it was obtained and handled.

When testing occurs well after the accident, there’s also a timing issue. The result may not accurately reflect the driver’s condition at the time of driving, which is what the State must prove.

Whole Blood vs. Serum: Why the Type of Sample Matters

Hospital blood draws and forensic blood draws produce different types of samples, and that difference matters significantly in a DWI prosecution. Forensic labs test whole blood, which contains all cellular components including red blood cells, white blood cells, and platelets. Hospitals test serum, which constitutes the remains after blood is centrifuged and cellular components are removed. Because serum contains more water than whole blood, alcohol concentrates at a higher level, and serum results run 16 to 25 percent higher than a true whole blood alcohol concentration.

A hospital serum result of 0.10 may reflect a true whole blood BAC of only 0.08 to 0.086. A result that appears to show intoxication may significantly overstate what a forensic test would show. Whether the State can use a hospital blood result in a criminal prosecution, and what that result actually means after proper conversion, is a legitimate defense issue in every accident case involving a hospital draw.

Building an Effective Defense When an Accident is Involved

Accident cases require managing more moving parts than a standard DWI. Chris Denuna and Nick Westbrook have represented hundreds of clients facing DWI charges involving minor accidents to serious collisions with lasting consequences.

When evaluating these cases, we review how the officer arrived at the scene, what assumptions were made, what the videos show, and whether the evidence of intoxication holds up independent of the accident. We understand the practical reality of these cases, including potential restitution, insurance claims, civil exposure, and how a conviction could impact our clients’ lives and futures.

Getting the criminal case right means accounting for all of these issues, not just the charge itself.

Frequently Asked Questions – DWI Accidents & Injuries in Texas

If there was an accident, does that mean I'm guilty of DWI?

No. The State must still prove intoxication beyond a reasonable doubt. An accident changes the context of the case, not the legal standard.

Does property damage automatically lead to a felony DWI?

No. Property damage alone doesn’t elevate the charge. Felony allegations arise when a serious bodily injury or fatality is involved.

Will an accident affect my ability to seal the record later?

Yes. A DWI involving an accident with another person is generally not eligible for nondisclosure, where your record is sealed by the court, even for a first-time offense. How the case is resolved affects what options are available.

What if another driver contributed to the accident?

That may become relevant to the investigation and the prosecution’s theory of the case, depending on the circumstances.

Does an accident affect plea negotiations?

In some cases, yes. Restitution, civil exposure, and injured parties all factor into how prosecutors approach negotiated resolutions in accident cases.

What if someone was seriously injured?

When serious bodily injury is alleged, the charge may become Intoxication Assault, which carries felony consequences and a higher evidentiary burden for the State.
