5 Effective Defenses To DUI Charges In San Bernardino County Your Legal Options Explained

5 Effective Defenses to DUI Charges in San Bernardino County: Your Legal Options Explained

If you’ve been arrested for driving under the influence (DUI) in San Bernardino County, California, you may wonder what your options are for defending yourself.

In California, DUI charges can be fought in several ways. Depending on the situation and the available evidence, one or more of the following defenses could be used to challenge the charges against you.

 This article will discuss some of the most common defenses to DUI charges and how they can help you fight your case. But remember, you should consult an experienced attorney for the best possible defense for your case. 

1. Challenging the Stop

One of the most common defenses to a DUI charge is challenging the legality of the stop that led to your arrest.

Law enforcement officers must have at least reasonable suspicion that you were driving under the influence, committing a crime, or committing a traffic violation before they can pull you over.

If there was no legal justification for making the stop, any evidence gathered after the stop may be inadmissible in court.

2. Contesting Field Sobriety Tests

Another common defense to a DUI charge is contesting the results of field sobriety tests (FSTs). These tests, such as the walk-and-turn or one-leg stand tests, are designed to assess your physical coordination and balance.

However, many factors can impact the accuracy of these tests, including medical conditions, nervousness, and poor weather conditions.

A driver’s performance on the field sobriety tests (FSTs) can often become part of a prosecutor’s case against them. However, it is important to note that these tests are notoriously inaccurate and subjective, so an experienced attorney may be able to challenge the results.

3. Questioning Breathalyzer Results

Breathalyzers are devices used to measure a person’s blood alcohol concentration (BAC) level. However, they can be inaccurate due to various factors, such as a person’s medical conditions or even the temperature outside. 

Breathalyzers are a standard tool used by law enforcement to measure BAC levels. However, many factors can affect test results, so an attorney may be able to cast doubt on their accuracy in court.

If you can successfully challenge the accuracy of the breathalyzer results, you may be able to get your charges reduced or dismissed.

4. Arguing Against Blood Tests

Another defense to DUI charges is to argue against the accuracy of blood tests. While blood tests are generally more accurate than breathalyzers, they can still be subject to errors.

For example, if the blood sample was mishandled or not stored properly, it could lead to inaccurate results.

A blood test is generally more accurate than a breathalyzer, but a skilled attorney may still be able to challenge the reliability of the results based on how and when the sample was taken.

5. Medical Defenses

Finally, if you have a medical condition that can impact your ability to perform sobriety tests or that can cause false positive results, you may be able to use this as a defense in your case.

For example, conditions such as diabetes or acid reflux can lead to false positives on breathalyzer tests.

Certain medical conditions can cause false readings when measured against DUI tests. An experienced attorney will know how best to use these defenses to build a strong case for their client.
