What types of evidence can be used in a DUI case?

In a DUI case, the types of evidence that can be utilized to establish impairment or intoxication are crucial for the prosecution's argument. The correct choice encompasses a broad range of evidentiary sources that directly contribute to determining the driver's state at the time of the stop.

Field tests, such as standardized field sobriety tests, provide objective measures of a driver's physical and cognitive abilities, which can indicate impairment. Breathalyzer results offer quantifiable data regarding blood alcohol concentration (BAC), serving as crucial evidence in demonstrating whether a driver is over the legal limit. Witness testimony, including accounts from police officers or other road users, can add context and support regarding the driver’s behavior. Video footage, whether from police body cameras or dashboard cameras, can visually document the driver's conduct during the stop, further enhancing the overall evidence presented.

In comparison, the other options lack the comprehensive nature required for effective prosecution in DUI cases. While expert testimonies and laboratory reports are helpful, they are more circumstantial and often not available at the moment of the stop, making them less immediate as evidence compared to the elements included in the correct answer. Driver’s background checks and vehicle history reports, although potentially useful in some legal contexts, do not directly address impairment or intoxication-related behavior
