Understanding Field Sobriety Tests in Maryland DUI Cases

Field sobriety tests are a common method used by law enforcement officers to determine if a driver is under the influence of alcohol or drugs. In Maryland, as in many other states, these tests are administered during a traffic stop when an officer suspects that a driver may be impaired. The purpose of these tests is to provide the officer with evidence to support a DUI arrest. However, these tests are not foolproof and can be challenged in court. Understanding how these tests work and the factors that can affect their accuracy is crucial for anyone facing a DUI charge in Maryland.

Field Sobriety Tests Explained

Field sobriety tests typically include the Horizontal Gaze Nystagmus test, the Walk-and-Turn test, and the One-Leg Stand test. The Horizontal Gaze Nystagmus test involves the officer observing the driver’s eyes as they follow a moving object, usually a pen or flashlight. The officer looks for involuntary jerking of the eyes, which can be an indicator of impairment. The Walk-and-Turn test requires the driver to take nine steps, heel-to-toe, along a straight line, turn on one foot, and return in the same manner. The One-Leg Stand test involves the driver standing on one leg while counting aloud. These tests are designed to assess a driver’s balance, coordination, and ability to follow instructions.

However, the results of these tests can be influenced by a variety of factors unrelated to alcohol or drug impairment. For instance, medical conditions such as inner ear problems, neurological disorders, or injuries can affect a person’s balance and coordination. Medications, fatigue, and even nervousness can also impact a driver’s performance on these tests. Environmental factors such as uneven or slippery surfaces, poor lighting, and inclement weather can further compromise the accuracy of field sobriety tests. Given these variables, it is possible to challenge the validity of these tests in court.

Legal Grounds for Challenging Field Sobriety Tests

Challenging field sobriety tests in Maryland DUI cases involves questioning the administration, conditions, and interpretation of the tests. One of the primary grounds for challenging these tests is the officer’s failure to follow proper procedures. Field sobriety tests must be administered according to specific guidelines established by the National Highway Traffic Safety Administration (NHTSA). If the officer deviates from these guidelines, the accuracy of the tests can be called into question. For example, if the officer did not provide clear instructions, did not demonstrate the test, or did not score the test correctly, these procedural errors can be used to challenge the test results.

Another ground for challenging field sobriety tests is the influence of external factors. As mentioned earlier, environmental conditions can significantly affect a driver’s performance. If the tests were conducted on an uneven surface, in poor lighting, or during adverse weather conditions, these factors can be used to argue that the tests were not reliable indicators of impairment. Additionally, if the driver has a medical condition or is taking medication that could affect their performance, this information can be used to challenge the test results. It is important to gather and present evidence that supports these claims, such as medical records, witness statements, and photographs of the test site.

The officer’s training and experience can also be scrutinized when challenging field sobriety tests. Law enforcement officers are required to undergo specific training to properly administer and interpret these tests. If the officer did not receive the appropriate training or has limited experience in conducting field sobriety tests, this can be used to question the accuracy of the test results. Cross-examining the officer about their training and experience can reveal inconsistencies and weaknesses in their testimony.

The Role of an Experienced DUI Defense Attorney

Challenging field sobriety tests in Maryland DUI cases requires a thorough understanding of the law, the science behind the tests, and the specific circumstances of the case. An experienced DUI defense attorney can play a crucial role in mounting an effective challenge to these tests. The attorney will review the details of the traffic stop, the administration of the tests, and the officer’s conduct to identify any procedural errors or inconsistencies. They will also gather and present evidence to support the argument that the test results were influenced by external factors or medical conditions.

An attorney will know how to cross-examine the arresting officer to expose weaknesses in their testimony. This may involve questioning the officer about their training, experience, and adherence to NHTSA guidelines. The attorney may also call upon witnesses to testify about the limitations and potential inaccuracies of field sobriety tests. These witnesses can provide valuable insights into how medical conditions, medications, and environmental factors can affect test results.

In addition to challenging the field sobriety tests, a DUI defense attorney will explore other aspects of the case to build a strong defense. This may include questioning the legality of the traffic stop, examining the accuracy of breathalyzer or blood test results, and identifying any violations of the driver’s rights. By taking a comprehensive approach, the attorney can create a compelling case that raises reasonable doubt about the driver’s impairment.

Verdicts & Settlements

DUI

All Charges Dropped

Found in his parked car with a friend and some open bottles, our client was facing a fourth DUI offense, along with 3 years of prison time and 2 more for probation violation. We didn’t back down in court, and the state dropped all charges after a short recess. Our client did not receive jail time, points, or probation – and he only paid a $50 fine.

DUI

Probationary Deal on a Second Offense

Our client had a .18 BAC in a notoriously heavy-handed jurisdiction, Harford County, where people can easily do 60 days active time on a second offense. Our firm negotiated a plea deal for our client that achieved no conviction, no points, and no jail. The Judge was incredibly impressed with the mitigation package we presented on behalf of client, who was very pleased with the results.

DUI

No Jail Sentence

Our firm secured a no-jail sentence for our client from a very tough Judge in Frederick County. Our client blew a .20 on a third offense, and the prosecutor was asking for active jail time. The Judge said the mitigation package we devised for the client made all the difference and led him to ignore the prosecutor’s jail recommendation in favor of just probation.

DUI

Charge Reduced

One of our DUI clients was facing up to 1 year in jail if convicted, plus $1000 in fines, 12 points on her driving record, and 3 years of supervised probation. By negotiating with the prosecution, we were able to secure a much better result. Our client did not receive a conviction, points, or jail time – instead, she paid only a few hundred dollars and received 1 year of unsupervised probation.

DUI

Not Guilty

After his fifth DUI charge, our client was facing up to 3 years in prison for a conviction. By showing that the field sobriety test result was affected by the client’s disability, our defense attorneys were able to secure a “not guilty” verdict on all counts, after the jury deliberated for only 12 minutes.

DUI

Probationary Deal on 6th Offense

After being arrested for their sixth DUI, our client faced 3 years in jail, up to $3,000 in fines, and a system inclined to award maximum penalties to repeat offenders. Our team managed to secure a probationary deal with no jail time for this client.
