You can become an unsafe driver at bac levels of

a. 0.03.

b. 0.08.

c. 0.10.

A 0.03 I think its the best answer to go with

Your answer will probably be A. 0.03 because this is the start of when intoxication will begin to take effect. Take for example that you are considered legally drunk and cannot be driving at a count of 0.05 in Utah, U.S. starting later next year. But even before that, you are creating danger by risking it. Good Luck!

Iwould say a is correct
