TL;DR
CDL General Knowledge (South Dakota): a 124-question practice bank for the real CDL Permit & Endorsement Exams standard, 2 full papers of 50 questions each with no repeats, every question citing the real regulation it comes from.
Where these questions come from
Every question in this bank cites a real source -- primarily FMCSA CDL Manual (77%) and 49 CFR (23%) of this exam's citations.
Real South Dakota 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 South Dakota Department of Public Safety (SD DPS), Driver Licensing Program's own site, verified 2026-09-03.
CDL license fee
$33 base CDL fee, plus $15 per endorsement, per the state-run South Dakota Truck Information site (sdtruckinfo.sd.gov). CDL renewal: $33 ($48 if it includes a hazmat endorsement, per a cached dps.sd.gov fee page).
Road/skills test fee
Third-party (private) testers may charge up to $90 per skills test attempt, per sdtruckinfo.sd.gov. State-administered road test fee not separately confirmed.
Minimum CLP hold before road test
14 days -- official: 'There is a 14-day waiting period between the date the CLP is issued and the date a skills test can be completed' (sdtruckinfo.sd.gov, Motor Carrier Handbook Ch. 8)
CLP validity
1 year -- official: 'A South Dakota commercial learner's permit (CLP) is issued for a one-year period for behind-the-wheel training on public roads'
Retake wait after a failed knowledge test
2-day waiting period between when a skills test is scheduled and when it can be taken, per sdtruckinfo.sd.gov. Knowledge-test-specific retake wait time not found on an official page.
Spanish-language knowledge test
English only
No dps.sd.gov or sdtruckinfo.sd.gov page explicitly states the CDL knowledge test's language options -- the DPS main CDL/fees pages redirected to a generic landing page during this research session. Secondary sources (news coverage of SD Senate Bill 164, February 2026, on codifying federal English-proficiency standards into state law) report SD's CDL knowledge test is English-only already. No official confirmation of a specific 2025/2026 dated change was found -- treat SD's 'English-only' status as pre-existing rather than a documented recent policy shift, pending direct confirmation with SD DPS.
- SD's official CDL guidance is split across dps.sd.gov (Driver Licensing Program, application/testing logistics) and sdtruckinfo.sd.gov (SD DOT's Motor Carrier Handbook, more detailed CDL qualification/fee rules) -- cross-reference both.
- A 2-day minimum gap exists between scheduling and taking the skills test, distinct from the 14-day CLP holding period.
- Third-party (private) skills testers may charge up to $90 per attempt, separate from state fees.
- SD Senate Bill 164 (2026 session) sought to codify federal English-proficiency roadside/testing standards into state law -- a live legislative item worth monitoring, not yet confirmed as enacted law as of this research.
