Delaware's official DMV CDL page and CDL Manual (v4.0, Feb 2025) do not state which languages the knowledge test is offered in. Third-party test-prep sites (not official) claim Spanish and Haitian Creole are available for the written test, with the skills test required in English -- unconfirmed against a Delaware .gov source. No evidence found of a 2025/2026 change to Delaware's test-language policy.
Delaware rolled out a 'CDL Skills Test Modernization' beginning February 26, 2025 with new pre-trip/basic-control testing protocols and an updated manual.
As of April 14, 2025 (mandatory June 23, 2025), Delaware requires CDL/CLP medical certificates to be submitted electronically by examiners on the National Registry; paper submissions no longer accepted.
Delaware has a Non-CDL Class A/B waiver track for farm, firefighting, and other emergency vehicles.
Hazmat endorsement requires a $5 endorsement fee plus a separate TSA background-check/fingerprinting fee paid directly to the TSA agent.
