Question 1

Is this accurate enough for legal use?

Accepted Answer

No — only law enforcement testing counts legally. Individual metabolism, food intake, and medications alter BAC.

Question 2

What counts as one drink?

Accepted Answer

Typically 12 oz beer (5%), 5 oz wine (12%), or 1.5 oz spirits (40% ABV), each ~14 g alcohol.

Question 3

Can I drive below the legal limit?

Accepted Answer

Any alcohol impairs driving. Plan rideshare, transit, or a designated driver.
