Delaware Tanker Vehicles Test

About the Delaware Tanker Vehicles Test

Delaware tanker drivers haul everything from gasoline to vegetable oil on busy roads like I-95 and DE-1. You face stop-and-go traffic near Newark and cross the C&D Canal bridges. Loads shift with every brake and turn.

Winter brings icy roads around Smyrna and foggy mornings on the Delaware Memorial Bridge. You must control surge without jackknifing. A spill on I-495 could shut down a major freight route.

Local industries include refineries, poultry plants, and chemical manufacturers near the Port of Wilmington. You'll often navigate narrow streets in Wilmington's industrial zone. The test checks your ability to load, drive, and unload safely.

This practice test uses real Delaware DMV questions. Each one prepares you for the actual exam. You don't need to memorize the whole handbook, but you should understand how liquid affects handling.

What This Test Covers

• Liquid surge and its effect on braking — critical on Delaware's winding Route 9 near Dover Air Force Base.
• Loading and unloading procedures — especially for chemicals at the Port of Wilmington.
• Special driving techniques for curves and ramps — I-95's S-curves near Christiana Mall require smooth steering.
• Emergency procedures for spills — DE-1 sees heavy tanker traffic near Rehoboth Beach in summer.
• Proper coupling and inspection — check your hoses before crossing the C&D Canal bridges.
• Weight distribution and baffles — hauling chicken fat from Sussex County plants means partial loads.

Study Tips

Focus on how liquid moves in a tanker. The Delaware DMV asks about surge at least three times on the exam. Practice with the CDL handbook's Section 2.9. You'll also need to know Delaware's specific inspection rules for hazmat loads.

Take this test until you score 100% three times in a row. On the real test, you get 20 questions and 25 minutes. That's about 75 seconds per question. Don't rush, but don't second-guess yourself. Delaware doesn't allow walk-ins – you must book a written test appointment online.

Delaware DMV Information

Delaware offers the Tanker Vehicles endorsement test at six DMV locations: Wilmington, Dover, Georgetown, Milford, New Castle, and Newark. You need an appointment. Book online at dmv.de.gov. The test costs $12 for the endorsement, plus a $25 CDL knowledge test fee if you haven't paid yet. Bring your valid Delaware driver's license and Social Security card.

The test is computer-based. You can take it in English or Spanish. If you fail, you must wait one day to retest. There's no limit on attempts, but you pay each time. Many drivers schedule at the Dover DMV because it's central and less crowded.

After you pass, you still need a skills test with a tanker vehicle. You can use a rental truck or your company's rig. Delaware requires the vehicle to have a valid inspection sticker and your CDL learner's permit must be current.
