The statement is false.
<h3><u>Explanation</u>:</h3>
The acronyms DUI stands for the Driving under influence and BAC stands for blood alcohol concentration. The blood alcohol concentration gives a value which signifies how many grams of alcohol is present in 100ml of blood. The BAC of a person is 0.2 means the person has 200mg of alcohol per 100ml of blood. Its much higher than the safety limit certified by American Medical Association.
The American Medical Association certifies that the maximum blood alcohol level can be upto 0.1 in worst case which can be allowed for a safe driving, although the levels under 0.05 are preferred. So the statement is false by its level.
