Nevada Practice DUI & Impaired Driving

What blood alcohol concentration triggers illegal per se administrative penalties for a driver holding a Nevada commercial driver license?

  1. A.
    0.08%
  2. B.
    0.02%
  3. C.
    0.06%
  4. D.
    0.04% Correct
The Why

The answer is "0.04%"

For the illegal per se administrative action listed in the DUI penalties table, a CDL holder's driving privilege is revoked at .04% or more but less than the .08% adult limit. Separate CDL consequences may apply for any detectable amount of alcohol.

Why the others miss

The traps in the wrong answers

A. 0.08%

This is the general adult limit; a CDL holder is covered by the stricter .04% figure in the illegal per se table. This answer uses the familiar .08% DUI figure most drivers remember, missing that CDL holders fall under a stricter row in the same table.

B. 0.02%

This is the under-21 figure in the illegal per se table, not the .04% threshold listed for a person who holds a commercial driver license. This answer recalls that Nevada sets a tighter alcohol threshold for certain drivers and pins the .02% under-21 figure to CDL holders instead.

C. 0.06%

The manual uses no .06% cutoff; the CDL figure is .04% and the general adult figure is .08%. This answer splits the difference between the .04% CDL threshold and the .08% adult limit under the assumption CDL sits somewhere between them.
