Drunk Driving Field Sobriety Tests in Monroe County 1st District Court: A Crucial Component of a DUI Defense

In a perfect world, one wouldn't find themselves being charged with a drunk driving offense, let alone be asked to submit to field sobriety tests. The truth of the matter, however, is that law enforcement officers are trained to administer these tests to assess an individual's level of intoxication and build a case for a DUI charge. In Monroe County 1st District Court, it's crucial for those facing DUI charges to have an attorney who understands the intricacies of field sobriety tests and how they can potentially be challenged in court.

Field Sobriety Tests: What They Are and How They're Conducted in Monroe County

The National Highway Traffic Safety Administration (NHTSA) recognizes three field sobriety tests that are designed to assess an individual's level of impairment due to alcohol consumption: the Horizontal Gaze Nystagmus (HGN), the Walk-and-Turn (WAT), and the One-Leg Stand (OLS). In Michigan, however, officers may deviate from these tests and administer tasks like singing the alphabet, counting backwards, or estimating time.

The tests sanctioned by the NHTSA have their own set of standards and protocols for administration. For instance, in the WAT, the defendant is required to walk heel-to-toe on a level surface. Any loss of balance, early start or finish, failure to touch heel-to-toe, usage of arms for balance, or incorrect number of steps could be interpreted as a failure, indicating the defendant's intoxication. The OLS test, on the other hand, requires the defendant to stand with one foot approximately six inches off the ground while maintaining balance. Swaying, hopping, or using arms for balance are considered signs of impairment. Finally, the HGN test is used to observe the involuntary jerking of a person's eyes as they gaze to the side – a reaction that may be exacerbated by alcohol consumption.

While these tests are designed to detect signs of impairment, they are not foolproof. Many sober people may fail these tests due to physical conditions, age, nervousness, or simply due to the difficulty of the tests themselves. Moreover, the administering officer's interpretation of the test results is highly subjective and may be influenced by bias, poor training, or even the officer's presumptions about the defendant's intoxication.

Furthermore, Michigan officers who choose to administer their own tests – which are not sanctioned by the NHTSA – can be accused of not following their own protocol. If a police officer cannot follow the rules set for field sobriety tests, what else did they potentially do incorrectly during the DUI investigation? A defense attorney skilled in DUI law can effectively challenge the validity of these unsanctioned tests, potentially undermining the prosecution's case.

Preliminary Breath Tests: The First Line of BAC Estimation in Monroe County

Alongside field sobriety tests, a Preliminary Breath Test (PBT) is another tool officers commonly use in DUI investigations. It's a roadside test administered to estimate the Blood Alcohol Content (BAC) of the defendant. In Michigan, the result of a PBT can be used to justify an arrest, but it typically won't be admissible in court with limited exceptions.

The decision to take or decline a PBT can be crucial in a DUI case. Police officers often do not clearly communicate the consequences of refusing a PBT. A common misconception is that refusing a PBT will result in the loss of one's driving license and incur 6 points on their license. However, this is not true. The sanctions for refusing a PBT in Michigan are much less severe - a 2-point civil infraction for those under 21, and 0 points for those over 21. Moreover, in most cases, this infraction is usually dismissed as part of an agreement with the prosecutor.

The decision to take a PBT for a Monroe County DUI Case should be made based on the likelihood of passing the test. If a defendant is confident that they are under the legal limit, taking the PBT may prevent an arrest. However, if there is uncertainty, declining the PBT could be beneficial as it leaves the officer with only their subjective observations and results from field sobriety tests (which can be challenged in court) to justify an arrest.

In some cases, the results of the PBT can be used to the defendant's advantage, especially in cases of a High BAC/Super Drunk offense. If the PBT reading shows a lower BAC at the time of the arrest compared to the BAC reading from a subsequent DataMaster test, it may suggest that the BAC was rising at the time of driving and therefore could have been below the legal limit when the defendant was driving.

It's important to note that while PBT results in Monroe County can be a useful piece of evidence, they are not as reliable as the DataMaster test, which is tested, calibrated, and checked regularly. PBT devices may go long periods without calibration and may be exposed to extreme temperatures, both of which can impact their accuracy.

In conclusion, understanding the nuances of field sobriety tests and PBTs is crucial when defending against a DUI charge in the Monroe County 1st District Court. A skilled attorney can effectively challenge the results of these tests and the officer's interpretation of them, and use the PBT results strategically to bolster the defense. This approach can lead to a successful defense, potentially resulting in a reduced sentence or even a dismissal of the charges.
