What this exam covers
Real Michigan 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 Michigan Department of State (Secretary of State)'s own site, verified 2026-09-03.

Administering agency
Michigan Department of State (Secretary of State)
CDL license fee
Secondary sources cite state fees for a standard CDL 'starting at $25' with endorsements adding $5-$10 each -- NOT confirmed on an official Michigan.gov fee table in this pass (the official CDL-apply page returned an HTTP 403 error when fetched directly and could not be retrieved)
Minimum CLP hold before road test
14 days (federal minimum; not independently re-confirmed on an official Michigan.gov page in this pass -- the official page could not be retrieved, HTTP 403)
Spanish-language knowledge test
Unconfirmed

UNCONFIRMED. Secondary sources claim the Michigan Secretary of State offers the written knowledge test, including for CDL, in Spanish (among other languages: Arabic, Chinese, Vietnamese), with a requirement to bring a qualified interpreter for non-English testing. This is a low-confidence, non-primary-sourced claim -- the official michigan.gov CDL application page returned an HTTP 403 (blocked) when fetched directly in this pass, so NO official confirmation was obtained for language availability, fees, or CLP terms. Given the active federal ELP crackdown and Michigan's proximity to a major FMCSA-regulated freight corridor, this field should be treated as a priority follow-up: contact Michigan SOS directly or retry the official page through a different access method before publishing anything about Spanish-language CDL testing in Michigan.
