What is the legal BAC limit for a driver under 21 operating a vehicle in Texas?
-
A.
0.08
-
B.
Zero Correct
-
C.
0.02
-
D.
0.05
The answer is "Zero"
Texas allows zero detectable alcohol in a driver under 21. Landing on C applies an under-21 trace allowance seen in another state and assumes Texas prints the same tolerance.
The traps in the wrong answers
A. 0.08
0.08 is the adult standard; the manual explicitly excludes minors from any tolerance. This answer treats the one BAC number a driver has seen as if it applied to every age group on the road.
C. 0.02
0.02 is a trace allowance some states use for underage drivers; Texas does not. This answer applies an under-21 rule seen elsewhere and assumes Texas prints the same tolerance.
D. 0.05
0.05 is a threshold discussed in federal safety debates, not the minor's limit here. This answer reads the number from a national headline as if it had already been adopted for young drivers in Texas.
