What is the standard size of a glass of wine according to SFST?

The standard size of a glass of wine according to the Standardized Field Sobriety Tests (SFST) is 5 ounces. This measurement is important in various contexts, including law enforcement and public safety, as it helps establish a baseline for understanding alcohol consumption and its effects on a person's impairment.

Knowing that a standard serving contains 5 ounces allows officers to use this information in conjunction with blood alcohol concentration (BAC) levels when assessing a driver's level of intoxication. Furthermore, standardized measures in alcohol serving sizes help ensure consistency in reports and evaluations related to driving under the influence (DUI) and other alcohol-related incidents.

Understanding these standard sizes is critical for both officers and the public when discussing intoxication levels and legal limits, as they provide a clear reference point for what constitutes moderate drinking versus excessive alcohol consumption.
