The charge of driving under the influence (DUI) is serious and can have a significant impact on the lives of those accused. In South Carolina, DUI arrests are subject to stringent legal procedures, and any deviations from these can lead to errors that might affect the validity of the arrest and subsequent charges. Understanding these common mistakes is crucial for those who find themselves facing DUI charges, as they can form the basis of a strong legal defense.

Improper Traffic Stops
One of the most common mistakes made by police officers in DUI cases involves improper traffic stops. According to South Carolina law, an officer must have reasonable suspicion to believe that a driver is violating the law to make a traffic stop. This could include observing erratic driving, speeding, or any other behavior that suggests impairment. However, if an officer stops a vehicle without reasonable suspicion, any evidence gathered during the stop, including the results of field sobriety tests or breathalyzer tests, may be deemed inadmissible in court. Challenging the legality of the initial stop can be a powerful defense strategy for those accused of DUI.
Failure to Follow Field Sobriety Test Protocols
Field sobriety tests are often used by officers to determine whether a driver is under the influence of alcohol or drugs. However, these tests are highly subjective and can be influenced by various factors, including the officer’s interpretation and the driver’s physical condition. Police officers must adhere to standardized procedures when conducting these tests, including the horizontal gaze nystagmus, walk-and-turn, and one-leg stand tests. If an officer deviates from these protocols, the validity of the test results can be called into question. For example, failing to give clear instructions, conducting the tests on an uneven surface, or not accounting for the driver’s medical conditions can all lead to inaccurate results and provide grounds for challenging the arrest.
Inaccurate Breathalyzer Administration
The breathalyzer test is a critical component of DUI arrests, providing quantitative evidence of a driver’s blood alcohol concentration (BAC). However, these tests are not infallible and are prone to human error. Police officers must be thoroughly trained in the operation and calibration of breathalyzer devices. Failure to properly calibrate the machine or administer the test according to established protocols can result in inaccurate readings.
Factors such as medical conditions, certain foods, or mouthwash containing alcohol can also affect the results. If there is any doubt about the accuracy of the breathalyzer results, it may be possible to challenge the evidence in court.
Lack of Probable Cause for Arrest
In order to make a DUI arrest, officers must have probable cause to believe that the driver is impaired. This means that there must be sufficient evidence to support the arrest, such as failed field sobriety tests, breathalyzer results indicating a BAC above the legal limit, or other observable signs of impairment. If the arresting officer cannot demonstrate probable cause, the arrest may be deemed unlawful. This is an important aspect of a DUI defense, as it can lead to the dismissal of charges if it can be shown that the arrest was not justified.
Improper Handling of Evidence
The integrity of the evidence is paramount in any DUI case. Police officers must follow strict protocols when collecting, storing, and presenting evidence to ensure that it is not tampered with or contaminated. This includes handling blood or urine samples, maintaining the chain of custody for all evidence, and accurately documenting all procedures.
Any lapse in these procedures can compromise the evidence and provide grounds for challenging its admissibility in court. For example, if a blood sample is not stored at the correct temperature or is not properly labeled, its validity as evidence can be questioned.

Failure to Read Miranda Rights
The Miranda rights are a critical aspect of any arrest, ensuring that individuals are aware of their right to remain silent and to have an attorney present during questioning. In DUI cases, if an officer fails to read the Miranda rights at the appropriate time, any statements made by the accused during custodial interrogation may be inadmissible in court. It is important to note that Miranda rights must be read once the individual is in custody and subject to interrogation. If there is any doubt about whether these rights were properly administered, it can be a significant factor in a DUI defense strategy.
Inadequate Documentation and Reporting
Police officers are required to document every aspect of a DUI arrest, from the initial traffic stop to the administration of tests and the final arrest. This documentation serves as a critical record of the events and is often scrutinized during legal proceedings. Inadequate or inconsistent reporting can undermine the prosecution’s case. For instance, if an officer’s notes contradict the official report, or if there are missing details about the testing procedures, it can raise questions about the accuracy and reliability of the evidence. Thorough and accurate documentation is essential to uphold the integrity of the arrest process.
Mistakes in Arrest Warrant Procedures
The issuance of an arrest warrant in DUI cases must follow specific legal procedures to be valid. If an officer fails to comply with these procedures, such as obtaining the warrant from a magistrate or failing to provide sufficient evidence to support the warrant’s issuance, the arrest may be challenged. This is particularly relevant in cases where a DUI suspect is arrested after an accident or when the arrest does not occur immediately. Ensuring that all warrant procedures are correctly followed is crucial to the legitimacy of the arrest.

Errors in Blood and Urine Testing Procedures
In some DUI cases, blood or urine tests are conducted to determine the presence of alcohol or drugs in the driver’s system. These tests must be carried out according to strict protocols to ensure accuracy. Mistakes in the collection, handling, or analysis of samples can lead to unreliable results. For example, using expired testing kits, improper labeling, or failing to adhere to time-sensitive testing procedures can all compromise the integrity of the evidence. When there are doubts about the reliability of blood or urine test results, they can be effectively challenged in court.
Lack of Training and Experience
The effectiveness of a DUI arrest often depends on the training and experience of the arresting officer. Officers must be adequately trained to administer field sobriety tests, operate breathalyzer machines, and follow legal procedures. A lack of training or experience can lead to errors in judgment and the mishandling of evidence. In some cases, an officer’s inexperience may be evident in their inability to properly assess a driver’s condition or to accurately interpret test results. Highlighting an officer’s lack of training or experience can be a key component of a DUI defense strategy.
Impact of Police Mistakes on DUI Cases
Understanding the impact of police mistakes on DUI cases is essential for anyone facing such charges. These errors can have significant legal implications, potentially leading to the reduction or dismissal of charges. By identifying and challenging mistakes made by the police, defendants can strengthen their defense and increase their chances of achieving a favorable outcome.
One of the most direct impacts of police mistakes is the potential for evidence to be deemed inadmissible in court. If evidence is obtained through an illegal traffic stop, improper testing procedures, or any other violation of legal protocols, it can be excluded from the trial. This can weaken the prosecution’s case and create reasonable doubt, which is crucial in achieving a not-guilty verdict.
Police mistakes can also undermine the credibility of the arresting officer and the overall integrity of the case. If it can be demonstrated that an officer failed to follow standard procedures or made errors in judgment, it can cast doubt on the reliability of their testimony and the validity of the arrest. This can be particularly influential in cases where the evidence is largely based on the officer’s observations and interpretations.
Additionally, the identification of police mistakes can lead to plea negotiations or the reduction of charges. Prosecutors may be more willing to negotiate a favorable plea deal if they recognize weaknesses in their case due to police errors. This can result in reduced penalties, such as lower fines, shorter license suspensions, or participation in diversion programs instead of incarceration.
Strategies for Addressing Police Mistakes in Court
When defending against DUI charges, it is crucial to develop a comprehensive strategy that addresses any mistakes made by the police. This involves thoroughly reviewing all aspects of the arrest, from the initial stop to the collection and handling of evidence. By identifying procedural errors and inconsistencies, an attorney can effectively challenge the prosecution’s case and advocate for their client’s rights.
One strategy for addressing police mistakes is to file pre-trial motions to suppress evidence. These motions argue that evidence was obtained unlawfully or in violation of the defendant’s rights and should therefore be excluded from the trial. By successfully suppressing key evidence, such as breathalyzer results or statements made without a proper Miranda warning, the defense can significantly weaken the prosecution’s case.
Another important strategy is to cross-examine the arresting officer and other witnesses to highlight inconsistencies or errors in their testimony. This can involve questioning the officer’s adherence to standard procedures, their observations during the arrest, and any discrepancies in their reports. By casting doubt on the officer’s credibility, the defense can challenge the reliability of the evidence presented against their client.
Expert testimony may be used to counter the prosecution’s evidence and provide alternative interpretations of the facts. For example, a forensic toxicologist can testify about the potential inaccuracies of breathalyzer tests or the effects of medical conditions on field sobriety test performance. This can provide a more comprehensive perspective on the evidence and support the defense’s arguments.
