Are you thinking of adding a doubles and triples endorsement to your Class A commercial driving license? Take a peek at the kind of questions you will be asked during the T endorsement exam, with our Missouri doubles and triples endorsement practice test – it’s totally free! A standard Class A driving permit will qualify you to operate single trailer combination vehicles such as flat-beds, livestock trucks and combination tank-trucks. If you want to drive a combination vehicle with two or three trailers, you will also need the doubles and triples endorsement on top of the compulsory Class A qualifications. Our CDL doubles and triples practice test for Missouri drivers will help you achieve this quickly, by showing you what to expect from the assessment, providing a source of realistic questions by which you can track your progress and as a result, reducing the likelihood that you will need more than one shot at passing the test.

We should warn you that driving students can only apply for a MO doubles and triples permit having successfully completed the other Class A written tests. If you have yet to pass the CDL general knowledge permit test, the air brakes endorsement exam or the Missouri CDL combination test, studying T endorsement material with this 2019 permit practice test now would be pointless. No matter how certain you are that you will ultimately require a doubles and triples endorsement for your license, familiarizing yourself with the study material for that test when there are other more pressing exams to pass is a bad idea. You could end up confusing this study material with the information you actually need for your next DPS permit test and undermine your chances of passing it. This DMV doubles and triples practice test will still be here when you need it later.

Future double and triple-trailer combination vehicle drivers who have not yet passed the CDL general knowledge assessment should stick with our CDL general knowledge practice test for Missouri drivers, until that initial permit test has been dealt with. The two mandatory Class A endorsements can be studied for in any order using our air brakes quiz and MO combination CDL practice test. Despite there being no rule stating in which order these qualifications should be acquired, we recommend leaving the Missouri combination CDL test until last. Much of the material explored on our Missouri CDL combination practice test and the real combination vehicles test has relevance to the doubles and triples endorsement, so sitting the two exams consecutively makes the most sense.

You will be familiar with many of the challenges faced by double and triple trailer drivers, as they are also relevant to single trailer truck drivers and as such, have been addressed in the Combination Vehicles endorsement material. One issue which will not be familiar to you is the “crack the whip” effect which can cause rear trailers in a chain to swing out of line when the vehicle changes lanes. Managing this risk and various other important topics such as coupling procedures, vehicle inspection and emergency protocol are explained in the T endorsement section of the permit book. Answering questions on our Class A license Missouri practice test for doubles and triples applicants will make sure you understand this information fully, before attempting to pass the real endorsement exam.
The questions you will face while working on this MO doubles and triples practice test for 2019 students are every bit as challenging as those on the real test. The grade you achieve here should give you a good indication of whether you have what it takes to earn a pass on the Missouri CDL doubles and triples test!
