What this exam covers
Real Utah 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 Utah Driver License Division (DLD) -- a separate agency from the Utah DMV, which handles vehicle registration only's own site, verified 2026-09-03.

Administering agency
Utah Driver License Division (DLD) -- a separate agency from the Utah DMV, which handles vehicle registration only
CDL license fee
CDL with Written Knowledge Test: $52.00 (Class A, B, or C, 5-year expiration); CDL Driving Skills Test: $78.00 for two attempts (per dld.utah.gov, found via search; not independently re-verified by direct page fetch)
Road/skills test fee
$78.00 covers two attempts at the driving skills test; retake fee after both attempts fail is $52.00 (skills) / $26.00 (knowledge retake)
Minimum CLP hold before road test
14 days -- CDL learner permit must be held before the skills test; matches the federal 14-day floor
CLP validity
180 days (dld.utah.gov/cdl-info page states "permit is good for 180 days")
Spanish-language knowledge test
English only

Confirmed directly from Utah DLD (dld.utah.gov/cdl-info/): "All CDL tests are administered in English only; the use of translation materials is strictly prohibited." This is stated as a federal-alignment policy (English proficiency needed for signs, records, and communicating with officials), not described as a new 2025/2026 change -- it reads as an existing, standing Utah policy, but Utah DLD does not offer Spanish (or any other language) for the CDL knowledge or skills test. Note this differs from Utah's REGULAR (non-CDL) driver license written test, which dld.utah.gov/written-knowledge-test/ confirms IS offered in multiple languages including Spanish -- the English-only rule applies specifically to CDL tests.
