Being charged with driving while intoxicated or driving under the influence is a serious matter that can have far-reaching consequences. A conviction can result in license suspension, hefty fines, mandatory alcohol education programs, increased insurance premiums, and even jail time. Beyond the legal penalties, a DWI or DUI conviction can affect your employment, your reputation, and your personal relationships. If you are facing DWI or DUI charges, having a skilled defense attorney is essential for protecting your rights and minimizing the impact on your life. In this article, we will explore DWI and DUI defense and how an attorney can help.
Understanding DWI and DUI Charges
While the terms DWI and DUI are often used interchangeably, some states distinguish between them. In general, both refer to operating a vehicle while impaired by alcohol or drugs. The legal limit for blood alcohol concentration is 0.08 percent for drivers 21 and older in all 50 states. However, you can be charged with DWI or DUI even with a BAC below the legal limit if the officer believes your ability to drive was impaired.
In recent years, drugged driving has become an increasingly common charge. With the legalization of marijuana in many states and the opioid crisis, law enforcement is paying more attention to drivers impaired by prescription and recreational drugs. Drug recognition experts are trained to identify signs of drug impairment, and chemical tests can detect the presence of drugs in your system. However, drug impairment is more difficult to prove than alcohol impairment, as there is no universally accepted legal limit for drugs.
The Traffic Stop and Probable Cause
Every DWI or DUI case begins with a traffic stop. For the stop to be legal, the officer must have reasonable suspicion that you committed a traffic violation or are engaged in criminal activity. If the officer did not have reasonable suspicion for the stop, your attorney can file a motion to suppress all evidence obtained from the stop, which may result in the dismissal of the charges.
After the stop, the officer must have probable cause to arrest you for DWI or DUI. Probable cause is typically based on the officer observations, such as the smell of alcohol, slurred speech, bloodshot eyes, and poor performance on field sobriety tests. Your attorney will carefully review the officer report and any dashcam or bodycam footage to determine whether there was sufficient probable cause for the arrest. If not, they can challenge the arrest and seek to suppress the evidence.
Field Sobriety Tests
Field sobriety tests are standardized tests used by law enforcement to assess a driver level of impairment. The three standardized tests approved by the National Highway Traffic Safety Administration are the horizontal gaze nystagmus test, the walk-and-turn test, and the one-leg stand test. These tests are designed to evaluate balance, coordination, and the ability to follow instructions.
However, field sobriety tests are not always reliable indicators of impairment. Many factors can affect performance on these tests, including age, weight, medical conditions, fatigue, nervousness, uneven road surfaces, and poor footwear. A skilled DWI attorney can challenge the results of field sobriety tests by pointing out factors that may have affected your performance and by questioning whether the officer administered the tests correctly.
You are not legally required to take field sobriety tests in most states. Your attorney can advise you on whether you should have declined the tests and can use the fact that you were not informed of your right to decline as part of your defense.
Chemical Tests and Implied Consent
Chemical tests, including breath, blood, and urine tests, are used to measure your BAC or detect the presence of drugs. Under the implied consent laws that exist in every state, by driving on a public road, you have implicitly consented to chemical testing if you are arrested for DWI or DUI. Refusing a chemical test can result in an automatic license suspension, and the refusal can be used as evidence against you in court.
Breath tests are the most common type of chemical test, but they are not always accurate. Breath testing machines can produce false readings due to improper calibration, operator error, medical conditions, and environmental factors. Your attorney will investigate whether the breath testing machine was properly calibrated and maintained, whether the officer was properly trained to operate it, and whether any factors may have produced a false reading.
Blood tests are generally more accurate than breath tests, but they are not infallible. Issues with blood testing can include improper collection, contamination, fermentation, and chain of custody problems. Your attorney will examine the blood testing procedures and may request that the blood sample be independently tested to verify the results.
Administrative License Suspension
In addition to the criminal case, a DWI or DUI arrest triggers an administrative process that can result in the suspension of your driver license. This process is separate from the criminal case and has its own deadlines and procedures. In many states, you have only a short period, often 10 to 15 days, to request an administrative hearing to contest the suspension. If you do not request a hearing within the deadline, your license will be automatically suspended.
A DWI attorney will help you request the administrative hearing and will represent you at the hearing. They will challenge the suspension by arguing that the officer did not have reasonable suspicion for the stop, did not have probable cause for the arrest, or did not properly administer the chemical test. If successful, your license suspension may be lifted, allowing you to continue driving while your criminal case is pending.
Building Your Defense
A skilled DWI attorney will examine every aspect of your case to identify defenses and weaknesses in the prosecution evidence. They will review the police report, dashcam and bodycam footage, breath or blood test results, maintenance records for testing equipment, and the officer training and certification records. They will look for procedural errors, constitutional violations, and factual inconsistencies that can be used to challenge the charges.
Common defenses in DWI cases include lack of reasonable suspicion for the stop, lack of probable cause for the arrest, inaccurate breath or blood test results, failure to read Miranda warnings, violation of the right to an independent blood test, and denial of the right to counsel. Your attorney will determine which defenses apply to your case and will develop a defense strategy accordingly.
In some cases, your attorney may file pretrial motions to suppress evidence, which can significantly weaken the prosecution case or lead to dismissal of the charges. If a motion to suppress is granted, the prosecution may be unable to proceed without the suppressed evidence.
Plea Negotiations and Alternative Sentencing
Not every DWI case goes to trial. In some cases, your attorney may be able to negotiate a plea to a reduced charge, such as reckless driving or wet reckless, which carries lesser penalties. This is more likely in cases where the evidence is weak, the BAC is borderline, or it is your first offense.
Many states offer alternative sentencing programs for first-time offenders, such as deferred adjudication, pretrial diversion, or ignition interlock device programs. These programs may allow you to avoid a conviction on your record or to have the charges dismissed upon successful completion. Your attorney will explore all available alternatives and advocate for the most favorable outcome.
If you are convicted, your attorney can advocate for lenient sentencing. They may present mitigating factors, such as your clean criminal record, your employment, your family responsibilities, and your willingness to attend alcohol education programs, to persuade the judge to impose a lighter sentence.
The Consequences of a DWI Conviction
The consequences of a DWI conviction extend far beyond the legal penalties. A DWI conviction stays on your criminal record and can affect your ability to get a job, obtain professional licenses, rent an apartment, or volunteer with organizations. It can also result in significantly higher auto insurance premiums or the cancellation of your insurance policy.
For certain professions, a DWI conviction can be particularly damaging. Commercial drivers, healthcare workers, teachers, and government employees may face additional professional consequences, including the loss of their professional license. If you hold a commercial driver license, a DWI conviction can result in the loss of your CDL, even if you were driving your personal vehicle at the time.
Repeat offenders face increasingly severe penalties. A second or third DWI conviction can result in mandatory jail time, longer license suspensions, higher fines, and the installation of an ignition interlock device. Your attorney will work to minimize the consequences, especially if you are facing enhanced penalties for prior convictions.
Conclusion
A DWI or DUI charge is a serious matter that requires skilled legal representation. The consequences of a conviction can affect every aspect of your life, from your driving privileges to your career to your personal relationships. A knowledgeable DWI defense attorney can examine the evidence, identify defenses, challenge the prosecution case, and work to achieve the best possible outcome for your situation. Whether through dismissal, reduction of charges, or minimized sentencing, the right attorney can make a significant difference in the outcome of your case. If you are facing DWI or DUI charges, do not try to handle the case on your own. Contact a qualified DWI defense attorney as soon as possible to protect your rights and your future.
