What this exam covers
Real Montana 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 Montana Motor Vehicle Division (MVD), Department of Justice's own site, verified 2026-09-03.

Administering agency
Montana Motor Vehicle Division (MVD), Department of Justice
CLP (permit) fee
No separate CLP-specific fee line; official fee schedule combines CLP and CDL under one 'CDL or CLP' fee table (see cdlFee)
CDL license fee
Intrastate CDL/CLP: $35.54 (ages 21-67, no REAL ID) / $61.29 with REAL ID. Interstate CDL/CLP: $41.72 (ages 21-67, no REAL ID) / $67.47 with REAL ID. Rates step down for ages 18-20. Confirmed via official mvdmt.gov Licensing Fees page.
Minimum CLP hold before road test
14 days minimum after CLP issuance before the skills test may be scheduled (confirmed on official 'Getting a New CDL in Montana' page)
Retake wait after a failed knowledge test
If pre-trip inspection or basic-control skills steps are failed, must wait at least 24 hours to retest. If those pass but the on-road driving portion is failed, must wait at least 1 week to retest (confirmed on official MVD page).
Spanish-language knowledge test
Unconfirmed

No official mvdmt.gov or dojmt.gov page or the 2026 CDL Manual explicitly states whether the CDL knowledge test is offered in Spanish or another non-English language. Montana's standard (non-CDL) license fee table lists a distinct 'FARSI B or C' fee line, suggesting some non-English testing infrastructure exists for standard licenses, but this does not confirm CDL knowledge test language options. No evidence found either way of a 2025/2026 policy change. Recommend a direct call to Montana MVD (406-444-1772) or the CDL Helpdesk (cdlhelpdesk@mt.gov, 406-444-3244) before publishing.
