In Texas, what is the blood alcohol concentration at which a driver 21 or older is considered legally intoxicated?
-
A.
0.08 Correct
-
B.
0.10
-
C.
0.15
-
D.
0.05
The answer is "0.08"
Texas law sets legal intoxication at a BAC of 0.08 for a driver 21 or older. The 0.10 pick in B trusts an older threshold a parent or older instructor learned and never updated to the figure Texas uses now.
The traps in the wrong answers
B. 0.10
Texas uses 0.08 for adult intoxication, not 0.10. This answer trusts a parent or older instructor who learned an earlier threshold and never updated to the 0.08 Texas uses now.
C. 0.15
Texas sets adult intoxication at 0.08, not 0.15. This answer picks a higher figure that shows up in aggravated-DWI news coverage instead of the ordinary threshold Texas sets.
D. 0.05
0.05 sits below the 0.08 threshold Texas sets for adult drivers. This answer picks a lower advisory figure some safety groups push for instead of the 0.08 Texas actually enforces.
