What this exam covers
Real Maryland 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 Maryland Department of Transportation Motor Vehicle Administration (MDOT MVA)'s own site, verified 2026-09-03.

Administering agency
Maryland Department of Transportation Motor Vehicle Administration (MDOT MVA)

Minimum CLP hold before road test

Spanish-language knowledge test
Available

Confirmed via an official MVA news release titled 'MVA Now Offering Commercial Driver's License Knowledge Test in Spanish' (published May 20, 2024, mva.maryland.gov/news/). Per MVA Administrator Chrissy Nizer, this applies ONLY to the knowledge test, administered in Spanish without an interpreter per FMCSA guidance (49 CFR 383.133(b)(3)); the skills test and pre-trip inspection remain English-only because applicants must understand verbal examiner instructions in real time. No 2025/2026 announcement rescinding this was found. This is a separate matter from the federal roadside English Language Proficiency (ELP) enforcement described in the research brief -- ELP enforcement applies to drivers during roadside inspections, not to knowledge-test eligibility -- so the two policies are not in direct conflict as far as could be verified. Given the volatility flagged in the brief, recommend a fresh live check of mva.maryland.gov immediately before publishing, since this rests on a 2024 announcement rather than a 2026 re-confirmation.
