Can You Be Charged With DUI Without Evidence?

Yes, drunk driving has devastating effects and an arrest for Driving Under the Influence (DUI) is one of the most serious charges a person can face. And one of the most common mistakes that people make after a DUI arrest is to assume the charge is undefeatable. Just because you were arrested for a DUI does not mean you have to be convicted for drunk driving. In many cases, the authorities may have made a mistake and it is entirely possible that you were not technically in violation of the law.

Regardless of the charges, you have rights! Fighting a drunk driving accusation can be overwhelming, even terrifying. The thought of the penalties that range from losing your license to jail time can be traumatic. But there is always a possibility of defeating your DUI charges. In order to do so, however, you need a skilled and experienced legal advocate.

The evidence, or lack of evidence, is often the key to the entire case. An experienced DUI attorney will meticulously evaluate your case and build an individualized and effective defense strategy that challenges the evidence brought against you.

The Lack of Evidence

It is important to remember that a DUI charge does not mean a conviction is inevitable. There are many proven defense strategies available to effectively fight a drinking and driving charge.

A knowledgeable DUI lawyer is aware of the pitfalls that can occur when a person is pulled over for suspected drunk driving. For instance, a capable attorney understands that everyone metabolizes alcohol differently. This makes it extremely difficult to look back in time to accurately pinpoint the blood alcohol level (BAC) at the exact time when the driver was behind the wheel. This difficulty increases with the passage of time and it can become increasingly speculative when trying to isolate the specific level.

Testing for DUI

When pulled over for drunk driving, there are several traditional DUI tests that can be administered. This includes breathalyzers and other chemical evaluations. All these assessments are prone to both human and mechanical error. Additionally, medical conditions, medications, and certain foods can produce false chemical test readings.

Due to the potential inaccuracies of these tests, a driver involved in a DUI arrest should immediately seek the guidance of a lawyer. There are many challenges to the validity of these tests for driving under the influence that only an experienced attorney identify. For example:

Field Sobriety Testing

When pulled over for suspected driving under the influence, the police will likely initiate a field sobriety test (FST).  The point of this is to gauge a person’s physical and mental impairment. Basically, the test examines whether the individual is mentally capable of following detailed directions that are given by the officer and whether they are capable of carrying out those instructions.

Field sobriety tests have long been used as a means of determining sobriety, but they are neither scientific nor objective. This test is not required in Arizona, and due to the subjective nature of the tests, they may not be recommended. So, it is almost always in your best interest to decline participation in any and all field sobriety tests. Refusal to participate cannot be used as incrimination against you nor does it authorize an arrest.

There are several physiological factors that could affect a driver’s performance during a sobriety test, including:

  • Age
  • Weight
  • Health
  • Poor hearing or eyesight
  • Fatigue
  • Weather conditions
  • Slippery road surfaces
  • Uneven surface
  • Anxiety
    Many of these conditions would make the test deceptive even for a completely sober person.

Breath Testing

Breathalyzer devices are not 100% accurate and depend heavily on proper operation. The most basic challenge to breath tests lies in the calibration, maintenance, and accuracy of the testing machine.  The results can even be compromised by operator error.

Additionally, a driver who submits to a breath test shortly after having a drink will likely have a higher blood alcohol reading because alcohol residue may remain in the mouth. This is known as residual mouth alcohol and will inflate test results.

Blood Testing

The integrity of a blood test hinges on whether the sample was properly collected, stored, and tested. Improper blood-drawing procedures are a common error. In addition, a driver who is pulled over soon after drinking and is given a blood test may have a higher BAC level at the time of the drawing because the alcohol level continues to rise for a period after it has entered the body.

Urine Testing.  This is the least reliable method of testing for blood alcohol content. These tests have strict protocols but are prone to human error. In addition, it is common that technicians fail to follow the required procedures, making test results unreliable.
