Understanding Field Sobriety Tests in Maryland

Field sobriety tests serve as a way for law enforcement to gauge your physical and cognitive impairment due to alcohol or drugs when driving. These tests typically include the Horizontal Gaze Nystagmus (HGN), Walk and Turn (WAT), and One-Leg Stand (OLS) tests. You may be asked to perform these tests after a routine traffic stop or during a DUI checkpoint. It is important to know your rights if you refuse a DUI test in Maryland. 

What are the Field Sobriety Tests

The Horizontal Gaze Nystagmus test involves observing the driver’s eye movements as they follow an object, such as a pen or flashlight, moved horizontally. Nystagmus, an involuntary jerking of the eyes, becomes more pronounced under the influence of alcohol or drugs and is what the officer will be looking for.

During the Walk and Turn test, the driver is instructed to take a certain number of steps along a straight line, heel to toe, then turn and return in the same manner. Officers assess the driver’s ability to maintain balance, follow instructions, and execute the task accurately.

In the One-Leg Stand test, the driver is asked to stand on one leg while keeping the other foot elevated for a specified duration. This test evaluates the driver’s ability to balance and focus, with impairment potentially leading to swaying or putting the foot down early or often while trying to balance.

4 Ways to Challenge Field Sobriety Test Results in a DUI Charge

If you’ve been charged with a DUI due to the results of your field sobriety test, you may have an easy DUI defense case. There is a lot that goes into the subjective nature of a field sobriety test, and if you don’t additionally have a breathalyzer or blood test, your lawyer can easily work with you to dispute the field sobriety test results.

DUI Defense #1: Environmental Factors

Despite their widespread use, field sobriety tests are not infallible. Various factors, including environmental conditions, physical limitations, and officer subjectivity, can impact test results. Adverse weather, uneven terrain, or medical conditions may affect a driver’s performance, leading to inaccurate conclusions and serving as a valuable DUI defense in DUI cases.

Your lawyer may argue the condition of the weather, road, or other factors hindered your ability to perform the test accurately – not due to the presence of drugs or alcohol. 

DUI Defense #2: Officer Experience and Subjectivity

Given the potential for inaccuracies in field sobriety tests, DUI defense attorneys often challenge field sobriety test results in court. Strategies from your lawyer may include questioning the officer’s training, the use of proper testing protocols, highlighting environmental factors that could have influenced the driver’s performance, or presenting evidence of medical conditions that may have affected the outcome.

Not all officers are equally trained or experienced in reading or administrating field sobriety tests. If they don’t account for environmental factors, this can lead to their conclusion being faulty and this is a DUI defense standpoint your lawyer may take. 

DUI Defense #3: Expert Witnesses

Expert witnesses can also provide invaluable testimony. Professionals specializing in fields such as forensic science or human physiology offer expert analysis and interpretation of test results, shedding light on potential inaccuracies or misinterpretations that can be used in your DUI defense.

DUI Defense #4: Strong Defensive Arguments on Accuracy

Supplementing expert testimony, scientific evidence can further add to the defense’s arguments. Studies and research findings may challenge the reliability and validity of field sobriety tests, emphasizing the subjective nature of these assessments. Your lawyer will use their time to read up and gather evidence that argues against the credibility of field sobriety tests to present in court during your case.
