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

In a DUI case, Breathalyzer results and video footage are considered strong forms of evidence because they provide objective and quantifiable data related to the driver's intoxication level and behavior at the time of the incident. Breathalyzer tests measure blood alcohol concentration (BAC) and can give law enforcement a precise indication of alcohol impairment. Video footage, such as traffic surveillance or officer body cameras, can capture the driver's actions before, during, and after being pulled over, further supporting or contesting claims of sobriety or impairment.

In contrast, personal opinions of witnesses can be subjective and may not provide concrete proof of intoxication. While police reports are important, they typically summarize the evidence rather than serving as evidence themselves. Character references from friends, while potentially useful in other contexts, do not pertain to the specific evidence of the DUI incident and therefore lack relevance in directly determining the driver's level of impairment.
