At a glance
Police reports aren't always accurate. Officers sometimes exaggerate signs of impairment, record field sobriety test failures that didn't happen, or write accounts that contradict video evidence.
When your attorney can prove the report doesn't match what actually occurred, it can lead to evidence being suppressed, damage the officer's credibility at trial, or strengthen your position in plea negotiations.
If something in your OWI report doesn't add up, document your own account immediately and work with an experienced attorney who can obtain video footage and identify problems with the officer's version of events.
You've been arrested for OWI in Wisconsin, and when you finally see the police report, something doesn't add up.
The officer claims you failed field sobriety tests you don't remember failing. The report says you were slurring your words when you know you weren't. Details are exaggerated, or just plain wrong.
It happens more often than you might think. And while it's frustrating, finding inaccuracies in your police report can actually become an important part of your defense.
Why Police Reports Matter in OWI Cases
In Wisconsin, OWI prosecutions depend heavily on evidence. The police report documents the officer's observations, the results of field sobriety tests, and the circumstances of your arrest.
Prosecutors rely on this report to build their case against you.
But police reports aren't always accurate. Officers may misremember details, exaggerate observations, or in some cases intentionally misrepresent what happened. When the report doesn't match reality, it can create opportunities to challenge the charges against you.
Common Inaccuracies in OWI Police Reports
Some of the most common problems defense attorneys find in OWI reports include:
-
Exaggerated signs of impairment. Officers are trained to look for specific indicators, such as red or glassy eyes, slurred speech, and the odor of alcohol. Sometimes reports claim these signs were present when they weren't, or overstate their severity.
-
Incorrect field sobriety test results. The report may claim you "failed" tests when video evidence shows otherwise. Officers sometimes record signs of impairment that didn't actually occur.
-
Improper test administration. Field sobriety tests must be conducted according to specific procedures established by the National Highway Traffic Safety Administration (NHTSA). If an officer doesn't follow the correct protocols (wrong number of passes on the eye test, incorrect timing, missing instructions) the test results may be invalid.
-
Inconsistencies with video evidence. Many traffic stops are recorded on dashcam or body camera footage. When the video contradicts what's written in the report, it raises serious questions about the officer's credibility.
How Inaccurate Reports Can Help Your Defense
Discovering that an officer lied or exaggerated in your OWI report doesn't automatically mean your case gets dismissed. But it can significantly impact your defense in several ways.
Suppression Motions
Your attorney can file a motion to suppress evidence if the officer's conduct violated your constitutional rights.
-
For example, an officer cannot extend a routine traffic stop to conduct an OWI investigation without reasonable suspicion of intoxication. If the officer claims in the report that you showed signs of impairment, but those signs didn't actually exist, the subsequent investigation may have been unlawful.
When evidence is suppressed, the prosecution loses access to key pieces of its case. Without certain evidence, they may be unable to prove the charges against you.
Attacking Credibility at Trial
If your case goes to trial, the officer's credibility becomes a central issue. When defense attorneys can demonstrate that the officer lied or exaggerated in the police report—especially when video evidence contradicts their written account—it calls into question everything else the officer claims.
Jurors who learn that an officer was dishonest may develop reasonable doubt about the entire prosecution. If the officer can't be trusted on one detail, why should they be trusted on others?
Strengthening Plea Negotiations
Even if your case doesn't go to trial, evidence of officer dishonesty can improve your position in plea negotiations. Prosecutors who recognize weaknesses in their case, including credibility problems with their primary witness, may be more willing to offer reduced charges or favorable terms.
What You Should Do
If you believe the police report in your OWI case contains false or exaggerated information, here's what to do:
-
Write down your own account immediately. Document everything you remember about the traffic stop, the field sobriety tests, and your interactions with the officer while the details are fresh.
-
Request all available evidence. Your attorney can obtain dashcam footage, body camera recordings, and any other documentation related to your arrest. Video evidence is often the most powerful tool for exposing inaccuracies in police reports.
-

The Bottom Line
Police officers are human, and their reports aren't always accurate. Sometimes mistakes are innocent. Other times, they're not. Either way, inaccuracies in your OWI police report can become a powerful defense tool when handled correctly.
If something in your police report doesn't match what actually happened, don't assume there's nothing you can do. An experienced attorney can review the evidence, identify problems with the officer's account, and build a defense strategy that holds law enforcement accountable for the truth.
