Real Vermont 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 Vermont Department of Motor Vehicles (DMV)'s own site, verified 2026-09-03.

Administering agency

Vermont Department of Motor Vehicles (DMV)

CLP (permit) fee

$18.00 (1-year CLP, new/renew/replacement) -- dmv.vermont.gov/licenses/fees

CDL license fee

$72.00 (2-year) or $108.00 (4-year); +$8/yr with motorcycle endorsement. Enhanced CDL: $108/$144.

Road/skills test fee

$39.00 road test + $29.00 road test scheduling deposit; Knowledge Test fee $39.00; Endorsement test $17.00

CLP validity

Conflicting official figures: the main CDL program page states 180 days, while the separate CLP subpage states 1 year, non-renewable. This discrepancy is unresolved and should be confirmed directly with VT DMV before publishing a specific number.

Spanish-language knowledge test

Unconfirmed

Could not confirm from an official Vermont DMV source whether the CDL knowledge test itself is offered in Spanish. Vermont's general (non-commercial) driver manual and learner-permit test are published in Spanish and roughly 15 other languages, but nothing on the official CDL pages states this extends to the CDL knowledge test. Third-party test-prep sites give contradictory, unofficial claims. No evidence found of a 2025/2026 policy change in Vermont specifically. Recommend confirming with VT DMV (802-828-2000) before publishing.

HazMat endorsement requires a TSA background check and fingerprinting.
School Bus endorsement must be issued directly by Vermont DMV; cannot be added to an out-of-state CDL.
All CDL/CLP holders must be registered in the FMCSA Drug & Alcohol Clearinghouse.
