Driving under the influence (DUI) is a serious offense that can lead to severe consequences, including fines, license suspension, higher insurance costs, job loss, and even jail time. If you find yourself facing a DUI charge, understanding your rights is crucial. This blog post will guide you through the essential aspects of DUI defense, your rights, and the steps you can take to protect yourself.

What is DUI?
DUI, or driving under the influence, typically refers to operating a vehicle while impaired by alcohol or drugs. In South Carolina, the legal limit of blood alcohol concentration (BAC) is 0.08% at which an evidentiary inference of impairment can be drawn. However, even lower levels can lead to charges if a driver exhibits signs of impairment. Evidence of drug use, including legally prescribed or over the counter medication can also be used.
Common Signs of Impairment
Law enforcement officers are trained to recognize signs of impairment. Some common indicators include:
Erratic driving: Swerving, speeding, variations in speed, or sudden stops.
Physical appearance: Bloodshot eyes, slurred speech, disheveled clothing or the smell of alcohol.
Behavioral cues: Incoherent responses, fumbling for documents, difficulty following directions, or aggressive behavior.
Understanding these signs can help you recognize when you might be at risk of being pulled over.
Your Rights During a DUI Stop
When stopped by law enforcement, it’s essential to know your rights. Here are some key rights you should be aware of:
Right to Remain Silent
You have the right to remain silent. While it’s often advisable not to be uncooperative with the police, you are not obligated to answer questions that may incriminate you.
Right to Refuse a Field Sobriety Test
Field sobriety tests are designed to assess your level of impairment. However, you have the right to refuse these tests, in which case, the police must make any charging decisions without the benefit of such tests.
Blood and Breath Tests
South Carolina law requires anyone under arrest and charged with DUI to submit to a breath test to determine the percent of blood alcohol concentration in your system. The law also requires a person charged to provide a blood sample, if requested by the arresting officer, to further test for alcohol and/or drugs. The results of these tests can be admitted as evidence of impairment at trial. You have the right to refuse such tests, but the law imposes an automatic driver's license suspension for a refusal. You also have the right to challenge the automatic driver's license suspension at an administrative hearing if you timely and properly file a request. Doing so usually allows you to obtain a temporary driver's license while the admin hearing is pending.
Right to an Attorney
You have the right to consult with an attorney before answering any questions or taking any tests. You should ask to be permitted to contact your attorney before submitting to any field sobriety tests or answering questions about alcohol or drug use at the time of the stop. It is crucial to have legal representation to navigate the complexities of DUI charges.
Understanding DUI Penalties
DUI penalties vary significantly by state and the specifics of the offense. Common penalties include:
Fines: Ranging from hundreds to thousands of dollars.
License Suspension: Temporary or permanent loss of driving privileges.
Jail Time: Depending on the severity of the offense, jail time can range from a few days to several years.
Ignition Interlock Device: Some offenders may be required to install an ignition interlock device that requires a clean breath sample before the engine will start.
Mandatory Alcohol and Drug Education Classes: Successful completion of the ADSAP program will be required before your driving privileges are restored.
Collateral Consequences: In addition to the legal penalties, a DUI conviction will result in higher insurance costs and could result in loss of current and employment opportunities, as well as having an adverse impact on one's family.
First vs. Subsequent Offenses
The penalties for a DUI conviction can increase with repeat offenses, as well as based upon the percent of blood alcohol content. The penalties can be dramatically more severe, if it involves an accident with injuries. A first offense that is not accident related is a misdemeanor and that may typically culminate in a fine and driver's license suspension until the requirements for reinstatement are met. More severe cases can be classified as a felony and carry a lengthy prison sentence.
Building a DUI Defense
If you are charged with a DUI, building a strong defense is critical. Here are some common defense strategies:
Challenging the Traffic Stop
If the police did not have legal grounds to stop you, any evidence obtained during the stop may be inadmissible in court. This can include breathalyzer results or field sobriety tests. In addition, the officer must have probable cause to make a DUI arrest. Absent probable cause, the arrest will not be valid and any evidence obtained as a result, will likewise be inadmissible.
Questioning the Breath Test Results
Breathalyzer tests can be inaccurate due to various factors, including:
Calibration Issues: If the device was not properly calibrated, results may be unreliable.
Proper Protocol: If the proper procedures and protocol were not followed to administer the breath test, the results can be suppressed.
Medical Conditions: Certain medical conditions can affect breathalyzer readings.
Proving Impairment
Your attorney may argue that you were not impaired at the time of driving, even if your BAC was above the legal limit. This can involve presenting evidence of your behavior, such as:
Witness Testimony: Friends or family can testify about your condition and circumstances before driving.
Video Evidence: Surveillance footage may show you driving safely.
Burden of Proof: The police and the state always bear the burden of proving the you guilty of DUI beyond a reasonable doubt. You never have to prove your innocence.
The Importance of Legal Representation
Navigating a DUI charge without legal representation can be daunting. An experienced DUI attorney can provide invaluable support by:
Explaining Your Rights: Ensuring you understand your rights throughout the process.
Building Your Defense: Crafting a defense strategy tailored to your specific case.
Mitigating the Impact: In some cases, where a complete defense may not be available, your attorney may be able to mitigate the severity of the impact upon you, by negotiating a plea deal to reduce penalties.
What to Expect in Court
If your case goes to court, here’s what you can expect:
Pre-Trial Hearings
Before the trial, there may be pre-trial hearings to address motions, such as suppressing evidence or dismissing charges.
Trial Process
During the trial, both the prosecution and defense will present their cases. Key components include:
Opening Statements: Each side outlines their arguments.
Witness Testimony: Witnesses may be called to testify, including law enforcement officers and experts.
Defendant's Rights at Trial: You have the absolute right to remain silent, you never have to testify, and this cannot be held against you at trial. You also have the right to testify, though if you choose to do so, you will be subject to cross examination. This part of the process should be thoroughly worked out with your attorney prior to making any decision. You also have the right to confront the witnesses against you, therefore, any witnesses must actually testify in court, rather than merely being quoted by a police officer, which would be impermissible hearsay.
Closing Arguments: Each side summarizes their case, emphasizing the strengths of their evidence and any weaknesses of the other's, before the jury or judge renders a verdict.
Verdict
After deliberation, the jury or judge will render a verdict of guilty or not guilty. If found guilty, sentencing will follow. If the case is tried to a jury, the jury must be unanimous in it's verdict before you can be convicted. Remember, the State always bears the burden of proof beyond a reasonable doubt, the Defendant never has to prove his innocence.
Post-Conviction Options
If you are convicted of a DUI, there are still options available:
Appeal Process
You may have the right to appeal the conviction based upon any legal errors during the trial. Trial courts can make mistakes and higher courts exist to correct those errors of law. An attorney can guide you through this process.
Expungement
If you are found not guilty at trial, or if your case is dismissed or nolle prossed (the State decides to drop the charges), you would be eligible to have your arrest expunged, allowing you to move forward without the stigma of a DUI on your record.
Conclusion
Facing a DUI charge can be overwhelming, but understanding your rights and the legal process is essential. Remember, you have the right to remain silent, to refuse certain tests, and to seek legal representation. Building a strong defense can significantly affect the outcome of your case. If you find yourself in this situation, you consult with a qualified attorney to navigate the complexities of your case and protect your rights more effectively.
Be informed and proactive. Have a knowledgeable and experienced attorney to represent you, who can take the necessary steps to defend you against the DUI charges and work towards a better resolution.
