Overview
The HazMat endorsement is for drivers who transport hazardous materials that require placards.
Hazardous Materials for Delaware CDL Applicants
Delaware handles heavy chemical and pharmaceutical freight along the busy I-95 Northeast corridor. With chemical and pharmaceutical manufacturing, port and container freight, food distribution driving much of the freight in Delaware, the Hazardous Materials material below is the part of the Delaware CDL that those employers screen for first.
HazMat is the one Delaware endorsement with steps beyond the knowledge test: a TSA security threat assessment (fingerprints) must clear before Delaware Division of Motor Vehicles adds the H, and it has to be renewed with the license. Start the TSA application early.
Where Delaware drivers use this
- Chemical and pharmaceutical manufacturing: roofing, coatings, and compressed-gas deliveries to job sites
- Port and container freight: placarded containers and ISO tanks coming through the ports
- Food distribution: cleaning agents, batteries, and other placarded retail freight
Most Delaware CDL work runs the I-95, I-295 corridors and the Dover area, so the examples in the practice questions lean on the vehicles and loads you will see there.
Delaware rules worth knowing
- Delaware DMV states its CDL manual covers CDL requirements, CDL procedures, testing requirements, and basic knowledge needed to obtain a CDL.
- Delaware DMV notes CDL renewals may only be completed within 30 days before expiration.
- Delaware began implementing the modernized CDL skills test at DMV locations on February 26, 2025.
Testing, appointments, and fees are handled by Delaware Division of Motor Vehicles. See the Delaware CDL classes and Delaware endorsements pages for the full licensing picture.
Common Delaware questions
- Is this Hazardous Materials material specific to Delaware?
- Yes. The knowledge test content is federal (49 CFR 383), so the questions apply in Delaware, and this page adds Delaware details: where you test (Delaware Division of Motor Vehicles), which Delaware industries use this license, and the Delaware corridors the examples are drawn from.
- Where do I take the Hazardous Materials knowledge test in Delaware?
- Knowledge tests are given by Delaware Division of Motor Vehicles. Bring your Delaware driver license, proof of residency, and your medical certificate; most Delaware offices require an appointment for CDL testing.
- How long do I have to study the Delaware Hazardous Materials material?
- Access lasts 120 days from purchase, which is enough to study, take the practice tests, and pass at Delaware Division of Motor Vehicles with time to spare. Retakes in Delaware are allowed after a short wait, so a second attempt is covered too.
- Does Delaware require anything extra for HazMat?
- Yes. In addition to passing the H knowledge test at Delaware Division of Motor Vehicles, Delaware HazMat applicants must clear a TSA security threat assessment (fingerprint-based). The endorsement is renewed with the license and the TSA check is repeated.

Topics Covered
Federal regulations require specific placards for each hazard class. Using the wrong placard or placing it incorrectly is a serious violation. The exam tests placard selection from the hazard class table and placement rules by quantity.
Every hazardous load must travel with shipping papers that identify the material, quantity, hazard class, and emergency contact. You will learn what information is required on the papers and where they must be stored in the cab.
Hazardous materials have strict rules for how they may be loaded together. Certain combinations are prohibited due to reaction risks. The exam covers compatibility tables and loading prohibitions by hazard class.
When hazardous cargo is involved in an accident, the driver's first actions are critical, including who to notify and how to use the Emergency Response Guidebook. Exam questions cover the exact steps for each type of HazMat incident.
HazMat drivers face additional security requirements including route planning restrictions and theft prevention protocols. The exam includes questions on reporting suspicious activity and the security plan requirements tied to the TSA background check.
