Are there any limitations on what types of evidence can be used in a DWI case?

Yes, there are certain limitations on the types of evidence that can be used in a DWI case in South Carolina. The type of evidence that can be used in a DWI case depends on the specific facts of the case and the applicable laws. Generally, prosecutors may submit physical evidence such as blood or urine samples showing the presence of drugs or alcohol in the defendant’s system, or circumstantial evidence such as statements made by the defendant, witness statements, or observations made by law enforcement officers. In addition, the evidence must be legally obtained. This means that the evidence must have been gathered in accordance with the law, including the Fourth Amendment’s protections against unreasonable search and seizure. For example, if a police officer stops a driver without reasonable suspicion or probable cause, or searches a vehicle without a proper warrant, any evidence obtained as a result may be inadmissible in court. In some cases, experts may also give testimony regarding the impact of alcohol on the driver, or may offer opinions as to why the driver may have been impaired. However, if the expert’s testimony is based on hearsay or lacks scientific basis, it may be excluded from evidence. Even if evidence is obtained legally, it must still be relevant to the case in order to be admitted. Relevant evidence is evidence that is logically connected to the defendant’s alleged offense and that tends to prove the defendant’s guilt or innocence. Ultimately, it is the judge who decides what evidence will be admitted in court.
