In Cincinnati, an OVI can carry serious consequences—jail, license suspension, steep fines, and a permanent criminal record. It can also disrupt your career, family life, and future.
However, OVI convictions often hinge on evidence that isn’t as reliable as it may seem. From illegal DUI traffic stops to faulty breathalyzers and flawed field sobriety tests, there are ways to challenge how the evidence was obtained and whether it holds up in court.
If you’ve been charged with OVI in Cincinnati or anywhere in Hamilton County, flawed evidence could be your strongest defense. At Luftman, Heck & Associates, our Cincinnati DUI lawyers have helped countless people in situations like yours fight OVI charges.

The Role of Evidence in Cincinnati OVI Cases
From the initial traffic stop to chemical testing and officer observations, the state must prove—beyond a reasonable doubt—that you were impaired while operating a vehicle. But when that evidence is weak, mishandled, or obtained unlawfully, it creates powerful opportunities for your defense attorney to challenge the charges.
Common forms of evidence in Cincinnati OVI cases include police dash cam or body cam footage, breathalyzer or blood test results, field sobriety test performance, and the arresting officer’s testimony. Each of these elements must meet strict legal and procedural standards. If they don’t, your lawyer may be able to file a motion to suppress, which can result in key evidence being excluded.
That’s why early and aggressive legal representation is so important if you’re arrested for OVI. A skilled defense attorney will carefully review the evidence, identify any violations, and use proven strategies to weaken the prosecution’s case. In many instances, successfully challenging DUI evidence can lead to reduced charges or even dismissal.
Improper DUI Stops & Lack of Probable Cause
Before police can stop a vehicle in Ohio, they must have reasonable suspicion that a violation or crime has occurred. To make an arrest for OVI, they must have probable cause to believe the driver is under the influence.
If the stop or arrest lacks proper legal justification, any evidence gathered afterward—such as breath test results or field sobriety tests—may be ruled inadmissible.
If police pulled you over based solely on vague suspicions—like driving late at night or “acting suspicious”—without specific, articulable facts, the stop may not meet the legal standard. In these situations, your attorney can challenge the stop or arrest. If successful, the court may exclude key evidence of impairment, which can significantly weaken the case.
Faulty Testing & Tainted OVI Evidence
Chemical tests—such as breath, blood, or urine tests—are often seen as the strongest evidence of an OVI. But these tests are far from foolproof. Mistakes in how these tests are administered, processed, or interpreted can significantly affect the results and your DUI defense.
Breathalyzers must be properly calibrated and maintained according to strict state guidelines. If the device is malfunctioning, not routinely inspected, or used by an untrained officer, it can produce inaccurate blood alcohol concentration (BAC) readings. The same goes for blood or urine tests, which must follow a documented chain of custody and lab protocols to ensure accuracy. Even slight errors—such as improper storage, contamination, or lab technician mistakes can compromise the reliability of the results.
Unreliable DUI Field Sobriety Tests
Field sobriety tests are another common form of evidence in OVI cases. But they’re often subjective and prone to error. These roadside DUI tests are used to help officers determine whether a driver is impaired, but factors unrelated to alcohol or drug use can easily affect the outcome.
Tests like the walk-and-turn, one-leg stand, and horizontal gaze nystagmus (HGN) rely heavily on the officer’s interpretation. Physical conditions such as back or leg injuries, inner ear issues, balance disorders, or even nervousness can cause a sober person to perform poorly. Environmental conditions—uneven pavement, poor lighting, bad weather—can also lead to unreliable results.
If the officer failed to properly administer the test or didn’t take medical or environmental factors into account, your attorney may be able to challenge its validity. In many Cincinnati OVIs, undermining the reliability of field sobriety tests can raise reasonable doubt and strengthen your DUI defense.
Violations of Your Rights in OVI Cases
When police collect evidence in a possible OVI case, how they gather it matters just as much as what they find. If officers violate your constitutional rights during the investigation or arrest, that evidence may be excluded.
One common issue involves Miranda rights. If you’re taken into custody and interrogated without being properly advised of your rights, any statements you make may be inadmissible in court. Similarly, if law enforcement conducts an illegal search, seizure, or DUI blood draw without a warrant or valid consent, it may violate your Fourth Amendment protections.
These violations happen more often than most people realize, especially in fast-paced traffic stops and OVI investigations. Fortunately, a n experienced DUI lawyer will know what to look for, from incomplete police reports to missing body cam footage or unconstitutional questioning. Identifying these missteps early gives you a stronger chance of challenging the case against you.

How an OVI Lawyer Challenges DUI Evidence
Successfully defending against an OVI charge often comes down to how quickly and effectively your attorney can challenge the prosecution’s evidence. At Luftman, Heck & Associates, we take a strategic, aggressive approach that pinpoints weaknesses early and uses every available legal tool to secure the best possible outcome.
One of the most powerful tools is a motion to suppress, which asks the court to exclude evidence that was illegally obtained or mishandled—whether that’s a faulty breath test, an unlawful traffic stop, or statements made without proper Miranda warnings. We also work with expert witnesses to evaluate chemical testing methods, inspect lab results, and refute inaccurate police observations. These professionals can provide critical insights that help cast doubt on the prosecution’s version of events.
Equally important is timing in your DUI case. Video footage from dash cams or body cams can be pivotal in showing what really happened. But this evidence is often overwritten or deleted if not requested promptly. That’s why early legal intervention is so important. The sooner you have a DUI attorney, the better your chances of preserving evidence, protecting your rights, and steering the case in your favor.
