What is different in Utah

Utah in particular

Three of Utah's Driver License Division offices, Farmington, Logan, and Tooele, do not process CDLs at all, so an applicant who lives near one of those three has to travel to a different office or use a certified third party tester instead.

The written exams themselves are federal

Utah 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.
