Understanding the DUI Trial Process: A Step-by-Step Tutorial

Introduction

If you have been charged with a DUI, you may feel overwhelmed by the complex consequences of your actions. In the following article, DUI process is explained from the time of detention by the police to the final ruling in court. In addition, this article explains what happens when you are pulled over on suspicion of driving under the influence and how to proceed with the subsequent court case.

Overview of the DUI Trial Process

Most people who are charged with a DUI don’t know how to get through the process. Many DUI cases start with a traffic stop for an alleged DUI offense or some other traffic offense. To defend a DUI case, one needs to have some knowledge of the typical DUI trial process. If a police officer has sufficient cause to believe that he or she has arrested an impaired operator, he or she will then take the operator into custody and book them at the police station for the DUI offense. For the purpose of the DUI charge, the offense was allegedly committed in the state where the arrest occurred.

The Pre-Trial Phase in a DUI case begins with the Arraignment (described above). In the Pre-Trial Phase of a DUI case, the Judge in a DUI case holds several pre-trial hearings and discusses several matters including several motions filed by both the State and the Defense in a DUI case. Most DUI cases are resolved prior to trial in a DUI case but if for some reason they are not resolved prior to trial then your DUI case will proceed to trial in a DUI case. At trial in a DUI case we go through the process of selecting a jury in a DUI case and then the opening statements of both the State and the Defense in a DUI case are presented to the jury in a DUI case. After the opening statements in a DUI case then both the State and the Defense in a DUI case present the testimony of their respective witnesses in a DUI case. Following the presentation of the testimony of both the State's witnesses in a DUI case and the Defense's witnesses in a DUI case then both the State and the Defense in a DUI case present their respective closing arguments in a DUI case. After the closing arguments of both the State and the Defense in a DUI case then the case is submitted to the jury in a DUI case for their deliberations in a DUI case. The consequences of a DUI conviction can include payment of fines and even time in jail for a DUI conviction. In FY 2024 for example 58% of all DWI convictions in North Carolina were sentenced at the lowest level of punishment, i.e. Level 5. Six percent of all such convictions in that year were sentenced to active time of confinement and 29% were sentenced to supervised probation in a North Carolina DWI case.

While most DWI cases are resolved through guilty pleas, 92% of all DWI convictions were entered by way of guilty plea, there are certain steps in the process of how DUI cases are processed that must be understood. The most important factor that affects a person’s DWI case is how their breath test results will affect their case and how a good DWI defense attorney can assist a client in navigating the DUI trial process. While the most recent DWI conviction statistics in North Carolina do not have to apply to your case, defendants charged with Breath Test Refusals must be informed of the new penalties for such offenses found in Trenton's Law.

At Vasquez Law Firm, we understand how scary a DUI charge can be. That is why we work hard to represent our clients to the best of our ability in order to get the best result possible. We work on a contingency basis, which means we only get paid if we win your case. We are able to work with you and come up with a payment plan that suits your budget. We are available 24 hours a day, 7 days a week if you need assistance right away. Vasquez Law Firm has two locations: one in North Carolina and one in Florida. We can serve our clients from both locations. We are a bilingual law firm and can serve our clients who speak languages other than English.

This flowchart guides you through the DUI trial process step by step. Start at the top with the traffic stop, and follow the arrows down to see how the case progresses through arrest, pre-trial, and trial phases, ending with the jury's verdict. Each box represents a key stage in the process.

Initial Steps: Traffic Stop and Booking

While being pulled over for DUI is a scary thing, many people are unaware of the typical progression of events after being pulled over for impaired driving. Below we have outlined the typical progression of events after being pulled over for DUI in North Carolina or in Florida for DUI.

  1. The Traffic Stop: When a person is stopped for DUI in North Carolina or in Florida for example, the initial stop must have been for some lawful reason, such as failure to come to a complete stop at a stop sign for example. The officer pulling you over for a DUI stop must honor your rights as well.
  2. Field Sobriety Tests: The officer will ask you to perform several different field sobriety tests to see if you are impaired and should be taken off of the road. The success rate for these tests to accurately determine impairment is very low for most of them.
  3. Breath Test for DUI: During the process of a DUI impaired driving arrest the officer will demand that the defendant take a breath test to get a reading of the defendant’s BAC or blood alcohol content. Refusal to submit to the test(s) for which the officer requests will result in additional criminal charges for the offense of refusal to take a breath test. In Florida the offense of refusal to take a breath test for which a defendant is charged is a second-degree misdemeanor with potential punishment of up to 60 days in jail and a $500 fine and/or community service.
  4. Arrest for DUI: After impaired driving arrest, the person who has been arrested for DUI will be taken down to the police station for booking and for BAC testing of the chemical sample that was collected from him or her during the DUI arrest.
  5. The Booking Process: This is the process of booking the DUI arrested person for jail. The process includes finger printing, taking of a picture for the arrested person’s ID, as well as collecting other personal information about the arrested person. In addition to this information, the person arrested for DUI will be required to provide a chemical sample for testing of the person’s BAC during the DUI arrest.

At Vasquez Law Firm, we have years of experience defending clients against the harsh charges of DUI. Most traffic stops end in a DUI arrest, and it is very important to know your rights during the stop, as well as the consequences of each stop and test, in order to defend against an illegal arrest and/or misuse of evidence against you. It is also very important to act quickly in order to preserve your license for the 10 days following your DUI arrest. Our aggressive DUI attorneys are here 24 hours a day to provide a free evaluation of your DUI charges and to represent you in all of your DUI matters. Vasquez Law Firm is bilingual and we would be happy to serve you in Spanish (Se Habla Español).

Start at the top with the traffic stop, and follow the arrows down to see what happens next, all the way to the booking process. Each box represents a key step in the journey, helping you understand what to expect.

Court Appearances: Arraignment and Pretrial Hearings

DUI can be a very stressful offense for people and taking control of the situation by going through the DUI trial process can help ease the stress and anxiety of the charged individual.

  1. Arraignment: In the arraignment for your DUI case, the charges will be read to you and you can enter a guilty, not guilty or no contest plea for the DUI charges. The charges against you for DUI can include aggravated DUI charges or even DUI with property damage charges. In this important step in the DUI trial process, the Sixth Amendment right to be informed of the nature and cause of the charges against you will be enforced by your criminal defense attorney throughout the DUI trial process. The experienced DUI defense attorneys at Vasquez Law Firm will personally handle your DUI case and provide you with personal attention and you will have direct access to your criminal defense attorney every step of the way.
  2. Bail Hearing: In most DUI cases, the first hearing before a Judge is the Bail Hearing where the Judge will set the amount of bail and determine whether or not you will be released from custody prior to your DUI trial. The amount of bail that the Judge sets will generally be based on his/her perception of the amount of danger that you will pose to public safety while you are at large. It is possible that the Judge could deny you bail altogether at your first appearance, meaning that even if you have the money to pay for bail, you will not be released from custody after the arraignment. We will work hard to make sure that your rights are protected at this important hearing.
  3. Pretrial Hearings: Before your DUI trial can begin, the Judge, the State’s Attorney and your Attorney will attend several pretrial hearings. During these hearings the following matters can be heard by the Court and ruled upon by the Judge: Your Attorney’s motion to suppress evidence; Negotiations of a plea bargain; Other matters that need to be resolved prior to your trial. Although the majority of DUI cases are resolved by the parties entering into a plea bargain wherein the defendant’s DUI case is either dismissed or reduced as a result of the defendant’s guilty plea, Vasquez Law Firm has the necessary experience to handle your DUI case from start to finish.
  4. Discovery: Discovery is a part of the trial process where both sides of a case exchange evidence including police reports, photos, and the statements of witnesses. At Vasquez Law Firm, we prepare every case as if it is going to trial. This allows us to fully represent our clients in their case against DUI charges.

Each step of the DUI trial process must be understood by individuals facing charges of driving under the influence in order to receive the best representation possible. First time offenders accused of DUI account for approximately 60% of all DUI arrests annually. Additionally, the average DUI conviction rate in state courts is over 70%. It is also vital to understand the implications of a no-contest DUI plea, including how it affects a civil lawsuit against the DUI defendant. The skilled DUI lawyers at Vasquez Law Firm work tirelessly to aggressively defend our clients through all phases of the DUI process while maintaining the direct access of our clients to their attorney throughout the DUI trial process.

Trial Phase: Proceedings and Key Participants

Our experienced DUI defense attorneys at Vasquez Law Firm have provided this process for a DUI trial in hopes that it will help inform defendants of the steps that will take place at trial of their DUI case. Note that every DUI trial in the State of North Carolina proceeds in exactly the same manner and steps as detailed here. If you or someone close to you has been charged with a DUI, then it is likely that this is what will occur at your trial.

  1. Jury Selection: As mentioned above, there is a “jury” that decides your case at your DUI trial. Through questioning of potential jurors by both sides to your case, we attempt to select the “impartial” jurors in your case. The State has the opportunity to strike jurors for “cause” as well as exercise all of their “peremptory” challenges. For instance, in North Carolina, the State and the Defense each have 8 “peremptory” challenges that they can use in selecting an impartial jury in your case.
  2. Opening Statements: The two sides will give opening statements to the jury in regard to what evidence the respective sides will use to prove their respective contentions of fact in the case. The prosecutor will tell the jurors what evidence he will use to prove each of the elements of the charged offense(s) against the defendant. Thereafter, the defendant and his experienced attorneys at Vasquez Law Firm will outline all of the evidence that will be used to support the respective contentions of fact of the defendant.
  3. Witness Testimonies: The DA will call many different witnesses to try to prove their case against you including police officers, crime lab experts, etc. Each of these witnesses will be called by the DA and then be cross examined by your attorney. We have experienced DUI attorneys that have handled many DUI cases. We can explain the testimony of the many different witnesses called by the DA in your case. We have a large and bilingual staff at Vasquez Law Firm, and we have many Spanish speaking clients. We can explain all aspects of your case to you.
  4. Closing Arguments: The defense and the prosecution will give closing arguments to the jury. In these arguments the two sides will highlight the main points of their case and attempt to convince the jury to return a verdict in their favor. These arguments will summarize the evidence that was presented at trial.
  5. Jury Deliberation: The jury will retire to the jury room to discuss the case and arrive at a verdict which is then announced in open court. The key to the prosecution getting a guilty verdict in a DUI case is to prove each and every element of the offense charged beyond a reasonable doubt. In the case of a Level 5 DWI conviction (the most common level of punishment for a DWI conviction) the defendant will be placed on probation and required to pay a fine.

The trial process for a DUI case can benefit anyone charged with a DUI in understanding how the process works and can affect your case. According to the latest DUI conviction rates in North Carolina for the year of FY 2024, 92% of all DWI convictions were by way of guilty pleas. This further emphasizes the importance of choosing the right DUI attorney to best guide you through the trial process and help you receive the best possible results. Vasquez Law Firm offers competitive payment plans, and are available 24 hours a day, 7 days a week to handle any emergent matters that may arise. As experienced DUI defense attorneys, we treat each DUI case with the utmost care and strive to provide the best possible defense for our clients.

Sentencing and Consequences of a DUI Conviction

Because of the serious nature of DUI charges in North Carolina, if you have been found guilty of driving while intoxicated, you may be worried about the potential consequences that your sentence could have on your life.

  1. Sentencing Hearing: At the sentencing hearing for your DUI case the Judge will determine how serious of an offense you were involved in as well as consider your prior criminal conduct. We can assist you with the sentencing of your DUI case as well.
  2. Potential Penalties for a DUI: These will vary depending on several factors including prior DUI convictions, how high your BAC was and whether you were involved in an accident and caused serious physical injury or death to another person. First time offenders can expect to receive a 60 day sentence, a $200 fine and a 30 day license suspension. However, after serving 24 hours in jail, it is possible that the remaining time can be suspended. The longer you have been a drunk driver prior to your current conviction, the longer you will serve in jail and the more in fines you will pay. Also, if you have been convicted of multiple DUIs in the past, the DUI penalties will increase dramatically.
  3. License Suspension: As mentioned previously, after your DUI conviction your license will be suspended for several months to years. The new laws coming in 2026 may even increase the burden of having your license reinstated after a DUI conviction. For example, all DUI offenders may be required to install an ignition interlock device in their vehicles.
  4. Long-Term Consequences of a DUI Conviction: Most people do not realize the long-term consequences of being convicted of a DUI. These penalties can result in increased rates with your insurance company and even affect your ability to find employment. For non-citizens, even a first-offense DUI can result in removal from the U.S. or problems with obtaining a visa to return to the U.S. Felony DUI offenses can even result in an individual’s removal proceedings. Our skilled North Carolina DUI attorneys at Vasquez Law Firm can guide you through the complexities of your case. Vasquez Law Firm is bilingual and offers free initial consultations.
