Field sobriety tests are routinely presented as objective and standardized. Officers describe them as scientific. Prosecutors rely on them as indicators of impairment to obtain OVI convictions . But the National Highway Traffic Safety Administration (“NHTSA”) , which developed these tests, makes clear in its current training materials that the tests are not universally reliable and are not validated for everyone . This is not a defense invention. It is a limitation built

When people picture field sobriety tests during an OVI stop, they often imagine the One-Leg Stand (“OLS”) . It looks simple. It sounds simple. And officers routinely treat it as a reliable indicator of impairment. But the OLS test is one of the most misunderstood and misapplied tools used in Ohio OVI investigations. Despite its reputation as a straightforward balance test, the OLS is highly sensitive to physical limitations, medical conditions, anxiety, roadside environments

Most people pulled over for suspected OVI in Ohio are asked to perform the Walk-and-Turn test, also known as the heel-to-toe test. Officers describe it as simple, straightforward, and easy to follow. In reality, the Walk-and-Turn is one of the most complex divided-attention tests in the National Highway Traffic Safety Administration (“NHTSA”) system. It requires coordination, balance, mental focus, clear instructions, and multiple divided-attention skills that many complet

When someone is pulled over for suspected OVI in Ohio , most people assume the officer conducts the field sobriety tests under conditions that allow for accurate results. The truth is that the National Highway Traffic Safety Association (“NHTSA”) requires specific environmental conditions for these tests to have any reliability at all. Lighting, surface conditions, footwear, weather, distractions, and traffic all matter. Yet in real-world stops, officers almost never follow

When someone is stopped for suspected OVI in Ohio, the Horizontal Gaze Nystagmus ("HGN") test is often the first “scientific” tool the officer relies on. Most drivers know it only as “the eye test,” and officers often describe it as the most reliable field sobriety test . In reality, HGN is the most technical, the most error-prone, and the least consistently administered test in the entire NHTSA system. The moment an officer deviates from the required procedure , the result

When someone is charged with an OVI in Ohio , it often feels as though the entire system is stacked against them. Officers talk about standardized training, scientific procedures, and field sobriety protocols as if they are objective and neutral. But beneath the surface of the National Highway Traffic Safety Administration (“NHTSA”) Standardized Field Sobriety Testing system lies a flaw that experienced defense attorneys can use to shift how juries see the case. That flaw a

Field sobriety tests play a major role in OVI investigations . Officers rely on them to decide whether to arrest someone, prosecutors use them to justify charges, and courts often assume they are backed by reliable science. Most people have heard of the three main tests: the Horizontal Gaze Nystagmus (HGN) , Walk and Turn , and One Leg Stand . What most people do not realize is that these tests are only validated when they are performed under strict, standardized conditions.

When an officer conducts a roadside investigation for suspected OVI , much of what happens is guided by formal training . Officers are taught specific procedures, specific sequences, and specific methods for evaluating impairment. These procedures are not optional. They exist to create structure and consistency in a situation that otherwise relies heavily on human judgment. Over time, however, officers often drift from the procedures they were taught. They shorten instruction

Field sobriety tests often look official and scientific, but their reliability depends entirely on whether the officer followed very specific procedures. Most people do not realize that these roadside exercises only work when they are administered exactly as the National Highway Traffic Safety Administration ("NHTSA") designed them. If an officer changes instructions, rushes through the test, skips required steps, or conducts the tests in poor conditions, the results lose v

Ohio’s open container law is much broader than most drivers realize. Many people think you can simply place an open drink in the back of the car and be safe. Others believe an open container only matters if the driver is drinking. In reality, Ohio law restricts where any open alcoholic beverage can be stored inside a vehicle, and a simple mistake can lead to criminal charges or trigger an OVI investigation . This article explains what counts as an open container, the narrow
