What is different in Nevada

Nevada in particular

Nevada concentrates its own skills testing in just four offices out of thirteen CDL locations statewide, so most of this large, sparsely populated state depends on a third party certifier rather than the DMV to actually administer the drive test.

The written exams themselves are federal

Nevada decides the permit rules, the fees and who runs the skills test, but the knowledge you are tested on comes from 49 CFR Part 383 and is the same in every state, which is why the 145 questions here work wherever you apply.

Where you test

Only four Nevada DMV offices, in Elko, Winnemucca, Reno, and North Las Vegas, administer the driving skills test, and applicants elsewhere in the state typically test through an authorized third party certifier or school instead.
