What is the legal blood alcohol concentration (BAC) limit for adult drivers?

A Less than 0.08%

The legal blood alcohol concentration (BAC) limit for adults is less than 0.08%. (In Montana, the BAC limit for drivers under 21 years of age is less than 0.02%.) If your BAC is 0.08% or more, you are considered legally intoxicated and can be charged with DUI. (Note: An average 180-pound man will reach a BAC of 0.10% from the alcohol in three 1.5-ounce shots of 80-proof liquor, three 12-ounce cans of beer, or three 5-ounce glasses of wine before his body starts to break down the alcohol.)

In the midst of finishing up learning on the older app, it told me to download this newer version. However, I didn’t want to have to go through all those questions again, so I simply finished reviewing on the old app and took the practice test on this newer app. Upon completion of the tests, it would not let me move forward or see my score! How should I know if I have done well enough to pass if I cannot see my own score?
