Idaho DUI Defenses

There are a number of different defenses that can be utilized by a skillful DUI defense attorney to cast reasonable doubt on any DUI investigation. If you have been arrested for a DUI, you may be extremely worried about the impact it will have on your life. It is important to remember that an arrest does not equal a conviction, even if your BAC was over the legal limit.

Traffic Stops

Police need a good reason to stop drivers, like suspecting drunk driving or a traffic violation. They can't stop someone just because they feel like it. A lawful traffic stop requires Police will stop reasonable suspicion that you might have committed a crime - this includes a suspicion that you might be intoxicated or under the influence of drugs. Possible signs of driving impairment include:

  • Taking a turn too wide
  • Straddling or crossing lane lines
  • Weaving and swerving
  • Striking or almost striking another vehicle
  • Braking too quickly
  • Speeding
  • Running red lights or stop signs

If an officer stops you for an unrelated traffic violation, such as speeding, you may end up with a drunk driving charge. The officer may smell alcohol on your breath, hear slurred speech, or observe bloodshot eyes. These can be possible signs that provide the officer with probable cause for a drunk driving arrest.

Potential Challenges to the DUI Traffic Stop

  • Reasonable Suspicion
  • Pretextual Stop
  • Roadblock or Avoidance of a Roadblock

A Traffic Stop is often the first step in a DUI investigation. An experienced attorney will be able to help you navigate through the defenses available due to an illegal or unjustified traffic stop. 

Officer Confirmation Bias

Confirmation bias is defined as "the tendency to interpret new evidence as confirmation of one's existing beliefs or theories". In criminal investigations this is the tendency of law enforcement to interpret new information in a way that conforms with their pre-existing beliefs about the case.

Indicators of Intoxication

Pursuant to Idaho law, officers must have multiple indicators of intoxication in order to initiate a DUI investigation. This is not always the case...

Field Sobriety Tests

An experienced DUI attorney will be able to show how difficult these tests are to pass, even sober, and what factors the officer failed to take into account when administering the tests.

Breath and Blood Testing

Breath tests are considered reliable enough to stand up in court, but that doesn't mean they don't come with a margin for error. If drivers are tested and the results are close to the legal limit, DUI attorneys can often argue that the machine gave an incorrect reading, and therefore help your case. 

Breath test machines must be properly maintained with regular accuracy checks and calibration.  Failure to do so will result in the breath test machines giving inaccurate test results.  Proper records must be kept if the test results are to be used against you.

Proper blood draw procedures must be followed if a blood test is given and the blood vial must be handled properly during the period prior to the testing or the BAC result will not be accurate. Blood is often shipped from location to location, leaving a lot of room for mishandling and contamination. Proper handling procedures, documenting chain of custody and preventing contamination, must be followed if the test results are to be used against you.

Presently, drug testing labs do not have the ability to identify drugs in an individual's system accurately enough to determine whether or not an individual was driving while actually under the influence. This means that DUI charges involving drugs can often be made more on speculation, rather than hard facts and evidence.

Warrantless Blood Testing and "Implied Consent" 

The recent United State Supreme Court decision in the case of Birchfield v. North Dakota, may have an impact on your case, depending on the circumstances. That case involved a man who refused to submit to a blood test to determine his blood alcohol concentration. At the time, as in many states, North Dakota law made it illegal to refuse a blood draw. The law said that by driving on state roads the driver implied consent for the taking of a blood sample. The Supreme Court overturned these laws. It said that a blood test is so invasive that it requires express consent or a warrant.

Refusal of Breath Testing

Some people mistakenly think that refusing to submit to a breathalyzer test will make it more difficult for the state of Idaho to prove that they were driving under the influence. This is not necessarily true.

Drug Recognition Experts

A Drug Recognition Expert (DRE) is a law enforcement officer trained to identify people whose driving is impaired by drugs other than, or in addition to, alcohol. While there is some training that these officers receive, they are not "experts." In the end, their conclusions are nothing more than a guess.
