Understanding the top defenses against DUI charges in New Hampshire can be the difference between a conviction and having your case dismissed.

Challenging the Legality of the Traffic Stop
One of the first steps in any DUI case is determining whether the officer had a legal reason to stop your vehicle. Law enforcement cannot stop a driver without probable cause, which means they must observe a traffic violation or have reasonable suspicion of illegal activity. If the officer stopped you without a valid reason, this could be grounds to have the DUI charges dismissed. For example, if you were pulled over for no apparent reason and no traffic laws were broken, your defense attorney could argue that the stop was unlawful. Without a legal stop, any evidence gathered afterward, such as the results of a breathalyzer test, could be thrown out.
Questioning the Accuracy of Field Sobriety Tests
Field sobriety tests are commonly used by police officers to determine if a driver is under the influence of alcohol or drugs. These tests may include walking in a straight line, standing on one leg, or following an object with your eyes. However, the results of these tests can be subjective and influenced by factors other than alcohol. For instance, certain medical conditions, poor balance, or even nerves can affect how someone performs. Additionally, the conditions of the test, such as uneven pavement or poor lighting, may also impact the results. Your lawyer can argue that these factors compromised the reliability of the tests.
Disputing Breathalyzer Results
Breathalyzer devices are used to measure the blood alcohol concentration (BAC) of a driver. In New Hampshire, if your BAC is 0.08 percent or higher, you can be charged with DUI. However, breathalyzer results are not always accurate. These machines must be properly calibrated and maintained to provide accurate readings. If the device was not properly maintained, or if the officer administering the test did not follow the required procedures, the results may be challenged. Furthermore, certain medical conditions, medications, or even the consumption of certain foods can lead to false positives on a breathalyzer test.
Arguing That the Driver Was Not Impaired
In some cases, a driver may argue that they were not impaired at the time of the stop. While the prosecution will rely on the results of field sobriety tests, breathalyzer readings, or blood tests, the defense can argue that these results do not accurately reflect the driver’s condition. Factors such as fatigue, stress, or illness can cause a driver to exhibit signs of impairment even when they are not under the influence of alcohol or drugs. Additionally, if the driver consumed alcohol after driving but before being tested, this could also challenge the DUI charge. For instance, if someone drank alcohol after parking their car and was later tested by police, the BAC results would not accurately reflect their state while driving.
Highlighting Inaccuracies in Blood Test Results
Blood tests are considered more accurate than breathalyzers for determining BAC, but even these tests can have errors. Mistakes can occur during the collection, handling, or analysis of the blood sample. Contamination or improper storage of the sample can affect the results. Additionally, if there was a delay between the time of the traffic stop and the blood test, the BAC levels might have risen, giving a false reading. A knowledgeable attorney can examine the details of how the blood sample was handled and analyzed to identify any potential errors or discrepancies.
Asserting a Medical Condition Affected the Results
Certain medical conditions can affect how a person’s body processes alcohol or how they perform on sobriety tests. For instance, conditions such as acid reflux, diabetes, or hypoglycemia can lead to false positives on breathalyzer tests or cause a person to appear impaired when they are not. Diabetes, in particular, can lead to the production of ketones, which can mimic alcohol in the bloodstream. Similarly, neurological disorders, like multiple sclerosis or inner ear problems, can affect a person’s balance and coordination, causing them to fail field sobriety tests. A defense based on medical conditions can be highly effective in challenging DUI charges.
Proving a Lack of Probable Cause for Arrest
Even if an officer stops a vehicle legally, they must still have probable cause to arrest the driver for DUI. This means the officer must have enough evidence to reasonably believe that the driver is impaired. Probable cause can be based on the results of field sobriety tests, breathalyzer readings, or the officer’s observations, such as slurred speech or the smell of alcohol. If there was insufficient evidence to justify the arrest, your defense attorney can argue that the DUI charge should be dismissed. For example, if the officer only based the arrest on a hunch or minor behavior that does not indicate impairment, this could be grounds for a successful defense.
Showing That the Driver Was Not in Actual Physical Control
In some cases, a person may be charged with DUI even if they were not actively driving the vehicle. For example, someone may be found sleeping in their car while intoxicated and still be charged with DUI. However, New Hampshire law requires that the driver be in actual physical control of the vehicle to be convicted of DUI. This means that the prosecution must prove that the driver had the ability to operate the vehicle. If the defense can show that the person was not in control, such as if the keys were not in the ignition or if the vehicle was parked in a way that made it clear they were not planning to drive, the charges could be dismissed.
Questioning the Officer’s Conduct During the Arrest
Law enforcement officers must follow specific procedures during a DUI arrest to ensure that the driver’s rights are protected. If the officer failed to follow these procedures, it could impact the validity of the DUI charge. For example, officers are required to read a person their Miranda rights after an arrest, informing them of their right to remain silent and their right to an attorney. If the officer failed to do this, any statements made by the driver could be inadmissible in court. Additionally, if the officer used excessive force or engaged in any misconduct during the arrest, this could also be used as part of the defense.
Raising Questions About Witness Testimony
In some DUI cases, witness testimony may play a role in the prosecution’s case. This could include statements from passengers in the vehicle or other drivers on the road. However, witness testimony is not always reliable, especially if the witness was far away from the scene or did not have a clear view of what happened. Additionally, witnesses may have biases or other reasons to misinterpret what they saw. Your defense attorney can challenge the credibility of witnesses by raising questions about their observations and pointing out inconsistencies in their statements. By doing so, the defense can create doubt about the prosecution’s version of events.
