What this exam covers
Real Minnesota CDL requirements

The knowledge tested here is federal (FMCSA) and identical nationwide -- what varies by state is who administers it and under what terms. Researched directly from Minnesota Department of Public Safety, Driver and Vehicle Services (DPS-DVS)'s own site, verified 2026-09-03.

Administering agency
Minnesota Department of Public Safety, Driver and Vehicle Services (DPS-DVS)
CLP (permit) fee
$26.75 (Class A, B or C instruction permit / CLP; official fee page notes it is 'available at driver exam stations only')
CDL license fee
Class A: $65 original / $60 renewal ($45/$40 if under 21); Class B: $57 original / $52 renewal; Class C: $50 original / $45 renewal; plus $4 School Bus processing fee where applicable
Road/skills test fee
Not itemized as a flat stand-alone fee (folded into the class application fee above). Confirmed separately: $40 no-show fee (missed appointment or cancel/reschedule <24 hrs before); $20 late-cancellation fee (24-72 hrs before); $10 retesting fee for 3rd+ written test after failing first two; $20 retesting fee for 3rd+ road test after failing first two.
Minimum CLP hold before road test
14 calendar days — official DVS CLP page lists this explicitly as step 3 of the CDL application process ('Hold the CLP for at least 14 calendar days')
Retake wait after a failed knowledge test
No explicit 'must wait N days' language found on official pages; what is confirmed is the fee escalation structure above (extra $10/$20 charges apply only from the 3rd attempt onward, implying no separate wait/fee penalty for the first two retakes)
Spanish-language knowledge test
Unconfirmed

UNRESOLVED even after direct fetches of the official DPS-DVS CDL hub, CLP page, fee page, and forms/resources page. Confirmed officially: the CDL manual (written and audio versions) is published in English only on DVS's own CDL forms/documents page, with no Spanish/Hmong/Somali version listed there — unlike the general DPS site, which offers Spanish/Hmong/Somali navigation chrome, and unlike Minnesota's separate Class D (regular) driver's test, which IS confirmed multilingual. No official DPS press release, FAQ, or policy page was found stating whether the CDL knowledge TEST itself is currently offered in Spanish at MN exam stations, and no dated 2025/2026 policy change was found either way. Do not publish a definitive answer for Minnesota without a direct call to DVS (651-284-1234) or a MN driver exam station.
