DUI Defense Strategies

If you have been charged with DUI, it is extremely important that you contact an experienced lawyer as soon as possible. Don’t make the mistake of facing the charges alone. A skilled lawyer will present your options, explore possible DUI defense strategies, and discuss whether a plea bargain or trial is appropriate. Hiring an lawyer is your best chance at lessening the severity of the charge and the penalties associated with it, or possibly getting the DUI dismissed.

WHAT IS CONSIDERED “DRIVING UNDER THE INFLUENCE?”

Forty-nine states (including Arizona) define having a Blood Alcohol Concentration (BAC) of 0.08% while driving as a crime; this is the level at which a driver is considered too impaired to drive. Utah considers a BAC of .05% as the threshold.

WHY IS BAC IMPORTANT?

Blood Alcohol Concentration, or BAC, is the percent of alcohol present in your bloodstream. It is measured by breathing into a breathalyzer, a blood draw, or a urine test. When an officer pulls you over for suspected DUI, they will most likely give you a breathalyzer test, as well as other field sobriety tests. The physical and mental effects of alcohol vary at different BAC levels, from a feeling of relaxation to gross impairment of motor control. There are many factors affecting a person’s BAC, such as gender, weight, amount of body fat, and how quickly the alcohol was consumed.

BAC levels are extremely important because prosecutors believe they accurately reflect how much an individual is impaired by alcohol. BACs are considered objective medical evidence and are often used to convict a driver of DUI.

DUI DEFENSE STRATEGIES

1. Refuting Test Results or Administration of the Tests

Since the results of a breathalyzer, blood, or urine tests are considered objective scientific evidence and can be used to convict an alleged offender, a DUI defense lawyer will investigate the accuracy of the results and whether the test was administered correctly. A lawyer will review the maintenance logs of the breathalyzer, the machine operator’s skills, the timeliness of the test after the stop; the chain of custody of blood sample; how field sobriety tests were administered. A defense lawyer will try to attack the admissibility of the test results, and the accuracy of the test result itself.

2. Conditions That May Affect Field Sobriety Test Results

There are only three field sobriety tests that are officially endorsed by the National Highway Traffic and Safety Administration (NHTSA): horizontal gaze nystagmus, walk-and-turn, and one-leg stands.

Some people have medical conditions that may mimic being impaired by alcohol. Severe allergies may cause red and watery eyes; being very tired, having a neurological condition, or a drop in blood sugar can cause slurred speech and delayed reaction times; certain medical conditions such as hypoglycemia in a diabetic, effects of a concussion, or balance issues related to an inner ear problem can cause dizziness, being unsteady, and confusion.

In addition, the field sobriety tests may be improperly administered, invalid field sobriety tests may be used, or the driver may be “tricked” into thinking that he is required to take them.

3. Refusing Field Sobriety Tests

There are a number of field sobriety tests an officer may ask you to perform to determine your level of impairment, such as touching your finger to your nose, reciting the alphabet backward, or walking a straight line. It should be noted, however, that there are only three Standardized Field Sobriety Tests (SFSTs) tests that are considered scientifically reliable, and have been officially endorsed by the National Highway Traffic and Safety Administration (NHTSA):

• Horizontal gaze nystagmus (HGN),
• Walk-and-turn (WAT), and
• One-leg stand (OLS)

You are not legally required to take these tests; however, you may still be arrested for DUI if an officer believes there is other evidence of impairment.

4. Improper Police Stop

Law enforcement must have a reasonable suspicion that you are driving while impaired in order to pull you over or detain you. They have to physically see the driver doing something wrong. If there was no reasonable suspicion for you to be pulled over, your lawyer can contest the stop and get the charges thrown out. If an officer has a hunch that someone is driving drunk, that is not considered a valid reason to pull you over. A lawyer will work to get the DUI dismissed since the officer did not have reasonable cause for the police stop.

If you are pulled over, it is important that you remain respectful to the officers and act responsibly. Being combative with officers will only work against you in the long run. You do not have to consent to a field sobriety test or a handheld portable breathalyzer test; however, if you refuse a blood draw, be aware that your license will be immediately revoked for 12 months.

5. Miranda Rights Violations

If you are arrested, police are required to read you your Miranda rights. If they do not follow this established procedure, anything you said after your arrest – even if you admitted to driving drunk — can be thrown out in court.

6. Necessity Defense

There may be a situation where you’ve had a few drinks, and then a situation arose where you believe you are about to get seriously hurt if you remain on the scene. This is one of the less common DUI defense strategies, but a skilled lawyer can use a “necessity defense” to show that the only reason you drove while impaired is that you were in fear for your physical safety.
