📘 Study Tips & State Info
Delaware DMV examiners focus hard on placarding. They'll ask you which placard goes with which hazard class, and they'll throw in scenarios like "you're hauling gasoline from the Delaware City Refinery — what placard do you display?" Know the difference between flammable liquid (Class 3) and combustible liquid. That's a common trick question.
Shipping papers are another big one. The basic description has to be in the right order: proper shipping name, hazard class, ID number, packing group. Delaware examiners will give you a list and ask which is correct. Practice writing them out until it's automatic.
Also, study the Hazardous Materials Table in the CDL manual. You don't need to memorize every entry, but you need to know how to read it — columns A through H. If you can find the right column for packaging exceptions, you'll pass that section.
Delaware DMV handles hazmat testing at all full-service CDL locations: Dover (the main office), Wilmington (on Airport Road), and Georgetown (in Sussex County). You need an appointment for CDL written tests — walk-ins aren't guaranteed, especially at Dover. Call or book online at dmv.de.gov.
Before you take the hazmat test, you must pass the General Knowledge exam and provide a valid Medical Examiner's Certificate. You also need to pass the TSA threat assessment (hazmat endorsement requires it). The TSA process takes 4-6 weeks, so plan ahead. The fee for adding the hazmat endorsement is $30, plus the $10 knowledge test fee.
One Delaware wrinkle: if you're hauling hazmat through the Delaware Memorial Bridge or the C&D Canal, you need to know the specific restrictions. The bridge has hazmat escort requirements for certain loads. The test might not ask about it directly, but it shows you're thinking like a local driver.
About the Delaware Hazmat Test
Delaware might be small, but we move a ton of hazardous materials through here. The Port of Wilmington handles everything from chemicals to fertilizers, and the refineries along the Delaware River keep tankers rolling on I-95 and Route 1. The Hazmat endorsement on your CDL isn't just a piece of paper — it's proof you know how to handle dangerous goods legally and safely.
This test covers federal hazmat rules plus the specific things Delaware examiners look for: proper placarding, shipping papers, loading and unloading procedures, and the security measures you need to follow. You'll also see questions about the Hazardous Materials Table and how to find the right information fast.
The Delaware DMV gives you 30 multiple-choice questions, and you need 24 right to pass. That's 80%. You'll take this test after you pass the General Knowledge exam. If you already hold a CDL, you can add the hazmat endorsement without retaking the skills test — but you still need to pass the written portion and the TSA background check.
Don't underestimate this one. Delaware examiners are thorough, especially on placarding and the basic description on shipping papers. Use this practice test to find your weak spots before you walk into the DMV.
