Free MS CDL Double/Triple Trailers Practice Test 2024
From the scenic Gulf Coast to the rolling hills, forests, and open farmlands of the Delta, you will see incredible diversity as you drive through Mississippi. Since you’re here, you must be considering adding the Double/Triple Trailers endorsement to your Mississippi Commercial Driver’s License (CDL). Before we dive into what is needed to obtain this certification, just know at the outset that adding it to your commercial license opens a new world of career opportunities and income-producing marketability. More on that point in a moment. The main hurdle is a 20-question multiple-choice knowledge test. To pass, you’ll need a score of 80%, which means getting 16 correct answers. After passing, you’ll receive the “T” endorsement on your CDL, authorizing you to pull two or three trailers (where allowed) (Mississippi CDL Handbook 2024).
As you drive through Mississippi, you’ll see historic small towns, agriculture, and of course the Mississippi River, but what you won’t see are 18-year-olds with the “T” endorsement. In the Magnolia State, you must be 21 or older to add this certification to your CDL, and even with a Double/Triple Trailers endorsement, you’re only allowed to pull double trailers. Rest assured, though, double trailers are often used throughout Mississippi for the transport of agricultural products, timber and wood, petrochemicals and industrial products, construction materials, and seafood from the Gulf Coast fishing industry. By now, you’re probably wondering, “Great! How can I best prepare for the test?”
With a sea of information online, it’s easy to drown in it all. That’s why a systematic, focused approach is key —and that’s exactly what you’ll get with our online Mississippi CDL Double/Triple Trailers practice test. With our test, you’ll receive instant, detailed feedback on each answer in real time instead of being overwhelmed with a host of end-of-test feedback. Up to date as of December 2024, it includes 20 multiple-choice questions that resemble what you will face at the DPS on your test day!
Once you’ve prepared, practiced with our free tests, and feel confident, simply apply at the DPS. You’ll show up with your documents, pay the fee, pass the official test, and immediately open your career to more opportunities.
