Delaware CDL Practice Test and Test Prep (2026)
Delaware gives CDL tests through Delaware Division of Motor Vehicles (DMV), a division of DelDOT. Here is what you will be tested on, which of our practice quizzes match each test, and what the skills test involves in Delaware.
Knowledge tests for a Delaware permit
- General Knowledge (all applicants) — practice General Knowledge (60 questions)
- Combination Vehicles (Class A) — practice Combination Vehicles (30 questions)
- Air Brakes (if the test vehicle has air brakes) — practice Air Brakes (40 questions)
- Any endorsement tests you need (P, S, H, N, T)
Permit minimum age: 18 (in-state driving) or 21 (interstate). Holding period before the skills test: 14 days. Permit validity: 365 days.
Delaware endorsement tests and practice
- Hazmat (H) practice
Delaware notes for this endorsement
Hazmat. Must be 21+, hold a CDL or CDL permit, and pass the HME knowledge test at a DMV office (proof of U.S. citizenship/lawful status required). Delaware is NOT a TSA self-managed state — fingerprinting and the TSA Security Threat Assessment are done through the federal Universal Enrollment Services program (IdentoGO/IDEMIA) at universalenroll.dhs.gov, with an $85.25 federal fee. The STA and endorsement renew on a 5-year cycle; requires ELDT for first-timers before the knowledge test.
- Tanker (N) practice
Delaware notes for this endorsement
Tank vehicle. Knowledge test only.
- Passenger (P) practice
Delaware notes for this endorsement
Passenger. Knowledge and skills test required (plus air-brake knowledge if the vehicle has air brakes); ELDT for first-timers.
- School bus (S) practice
Delaware notes for this endorsement
School bus. Requires a CDL with the passenger endorsement, ELDT, a skills/road test in a school bus, DMV vision screening (or a federal medical waiver), and formal training coordinated with the Delaware Department of Education; minimum age 18 and a clean-record/criminal-history review apply.
- Doubles/triples (T) practice
Delaware notes for this endorsement
Doubles/triples. Knowledge test only.
The Delaware skills test
Components: Pre-trip vehicle inspection (modernized checklist effective Feb 26, 2025), Basic control skills, On-road driving test.
Test vehicle: You must supply a representative commercial vehicle for the skills test, along with a valid registration and insurance card; the DMV does not provide a test vehicle.
Where and how to book: Delaware runs a Third-Party CDL Testing program under Delaware Administrative Code Regulation 2226: approved organizations may administer the CDL skills exam after submitting an application, examiner list, testing site, and an approved road-test route. You can also test at a DMV lane. DMV skills tests are by appointment only and are offered every weekday except Wednesday. Program contact: [email protected].
Waits and retests: Delaware is a small three-county state with a handful of DMV lanes (Wilmington/New Castle, Dover, Georgetown), so skills-test appointments can book out during peak periods — many drivers test through a third-party school that furnishes a truck and offers faster or dedicated slots (rough planning estimates, not a DMV figure).
Practice the inspection part with our pre-trip inspection guide. Research dated 2026-10-12; confirm testing details with Delaware.
