What is required for a DUI conviction apart from a BAC measurement?

For a DUI conviction, while a blood alcohol concentration (BAC) measurement is a critical piece of evidence, it is often not the sole factor that law enforcement and prosecutors consider. Additional indicators of impairment are essential in establishing whether a driver was indeed impaired at the time of the offense. These indicators can include observable behaviors such as erratic driving, the presence of physical symptoms (like slurred speech, bloodshot eyes, or difficulty maintaining balance), and the results of field sobriety tests.

When combined with the BAC results, these additional indicators help create a more comprehensive picture of the driver's condition, supporting the case for a DUI conviction. Courts look at the totality of the circumstances surrounding the incident, and multiple types of evidence can contribute to a stronger case. Thus, additional indicators of impairment are indispensable for upholding a DUI charge effectively.
