According to SFST, what is the size of a shot of whiskey (80 proof)?

A shot of whiskey, particularly at 80 proof, is typically standardized at 1.5 ounces. This standard measurement is widely accepted in the United States for various types of distilled spirits. Understanding this measurement is important in law enforcement and traffic safety, particularly when evaluating potential driving under the influence situations.

This knowledge can aid officers in assessing alcohol consumption accurately, as it helps correlate the amount of alcohol consumed with impairment levels. Accurate information on alcohol serving sizes is crucial for effectively implementing the Standardized Field Sobriety Tests (SFST) and ensuring the enforcement of DUI laws is based on sound evidence.
