Being charged with driving under the influence or impaired driving creates immediate legal problems that threaten your driving privileges, employment, and freedom. The consequences extend far beyond fines and court appearances to include license suspension, insurance rate increases, professional licensing issues, and potential jail time. Many people assume DUI charges automatically lead to conviction, but numerous defense strategies can challenge the prosecution’s case.
Our friends at Eastside DUI report that DUI enforcement involves standardized procedures that law enforcement must follow properly for charges to stand in court. When you’re facing impaired driving charges, an impaired driving lawyer can identify weaknesses in the prosecution’s case, challenge improper procedures, and build defenses that may result in reduced charges or case dismissal.
Challenging The Initial Traffic Stop
Police need reasonable suspicion to stop your vehicle. They cannot pull you over on a hunch or because they want to investigate potential DUI without specific articulable facts justifying the stop. Common justifications include traffic violations, equipment problems, or erratic driving patterns.
If the officer lacked reasonable suspicion for the initial stop, everything that followed becomes fruit of the poisonous tree. This includes field sobriety tests, breathalyzer results, and any statements you made. Successful suppression of this evidence often leads to case dismissal because the prosecution cannot prove their case without it.
We examine dash cam footage, officer testimony, and police reports to determine whether the stop was legally justified. Minor deviations from perfect driving don’t automatically create reasonable suspicion, and we challenge stops based on insufficient grounds.
Questioning Field Sobriety Test Administration
Standardized field sobriety tests must be administered according to NHTSA protocols to produce valid results. Officers who deviate from proper procedures generate unreliable test results that shouldn’t be admitted as evidence. Common administration errors include:
- Conducting tests on uneven surfaces or in poor lighting
- Failing to account for physical conditions affecting performance
- Giving unclear or improper instructions
- Scoring tests incorrectly
- Using non-standardized tests with no scientific validity
Medical conditions, injuries, age, weight, and footwear all affect field sobriety test performance. These tests are designed for healthy individuals under ideal conditions, and results become questionable when those conditions don’t exist.
We review video footage of your field sobriety tests to identify administration errors and factors that affected your performance unrelated to alcohol or drug impairment.
Disputing Breathalyzer Accuracy And Maintenance
Breathalyzer devices require regular calibration and maintenance to produce accurate results. Law enforcement agencies must follow manufacturer specifications for device maintenance and keep detailed records. Devices that haven’t been properly maintained or calibrated generate unreliable results.
Operator error also creates problems with breathalyzer results. Officers must observe you for a specified period before testing to make certain you haven’t consumed anything or regurgitated. They must follow proper testing procedures including control tests. Failure to comply with these requirements renders test results questionable.
Medical conditions like acid reflux, diabetes, and certain diets can produce elevated breath test results unrelated to alcohol consumption. Mouth alcohol from recent use of mouthwash or breath spray can also affect readings. We investigate these alternative explanations for elevated breath test results.
Blood Test Chain Of Custody Issues
Blood tests require proper collection, storage, and analysis to produce valid results. The chain of custody must be maintained from collection through laboratory analysis. Any gaps or irregularities in this chain raise questions about sample integrity.
Blood samples must be drawn by qualified personnel using proper procedures. They must be stored at appropriate temperatures and analyzed within specified timeframes. Fermentation can occur in improperly stored samples, creating alcohol that wasn’t present when the blood was drawn.
Laboratory analysis must follow established protocols. We review lab procedures, analyst qualifications, and quality control measures to identify problems that affect result reliability.
Rising Blood Alcohol Defense
Your blood alcohol concentration continues rising for 30 to 90 minutes after your last drink. This means your BAC when tested may be higher than it was when you were actually driving. The rising BAC defense argues that while your BAC exceeded the legal limit when tested, it was below the limit during the time you were driving.
This defense requires expert testimony about alcohol absorption rates, the timing of your last drink, and when the test occurred. It’s particularly effective when significant time elapsed between when you stopped driving and when testing occurred.
Challenging Officer Observations And Opinions
Officers often testify about bloodshot eyes, slurred speech, unsteady gait, and alcohol odor as evidence of impairment. These observations are subjective and can result from causes unrelated to alcohol or drug use. Allergies, fatigue, illness, nervousness, and medications all produce symptoms officers commonly attribute to impairment.
We cross-examine officers about their observations and present alternative explanations. Video evidence sometimes contradicts officer testimony about your appearance and behavior, undermining their credibility.
Medical Conditions Mimicking Impairment
Various medical conditions produce symptoms that appear similar to impairment. Neurological conditions affect balance and coordination. Speech disorders affect communication. Eye conditions cause abnormal pupil responses. Hypoglycemia and other metabolic disorders create confusion and disorientation.
We gather medical records and expert testimony establishing that your symptoms resulted from medical conditions rather than alcohol or drug impairment. This defense is particularly powerful when your BAC was borderline or when testing showed no alcohol or drugs in your system.
Protecting Your Rights And Your Future
Impaired driving charges threaten serious consequences that affect every aspect of your life. Many cases involve defenses that can result in reduced charges or dismissal when properly presented.
