About the Indiana Doubles and Triples Test
Topics Covered
- ✓Coupling and uncoupling procedures — Indiana examiners expect the full step-by-step sequence. Miss a step on a snowy day in Gary, and you've got a jackknife waiting.
- ✓Trailer stability and rollover prevention — Indiana's flat farmland might seem easy, but crosswinds on I-70 near Terre Haute can push a light trailer sideways fast.
- ✓Jackknife causes and prevention — Lake-effect snow on I-80/94 means slick roads. Knowing how to avoid a jackknife when a semi slams its brakes ahead of you is survival.

📘 Study Tips & State Info
Indiana BMV examiners love asking about the exact order of coupling and uncoupling. They don't want general ideas — they want the sequence. Start with securing the tractor, then the first trailer, then the second. Memorize it like a recipe. If you mix up the steps on the test, you'll mix them up on the road.
Pay attention to the section on trailer stability when braking in curves. Indiana has plenty of highway ramps that bank the wrong way. The manual talks about 'trailer push' — that's when your rear trailer tries to pass your tractor on a downhill curve. That's a real problem on I-74 coming into Indianapolis. Understand why it happens and how to correct it.
Finally, don't skip the air brake questions just because you passed General Knowledge. The doubles/triples test has specific questions about how air systems work with multiple trailers — like which gladhand goes where. Indiana examiners include those every time. Use our practice tests to drill those until they're automatic.
The Indiana BMV administers the Doubles and Triples test at all CDL testing locations across the state. You'll find them in major cities like Indianapolis (the BMV Central branch on N. Meridian Street), Fort Wayne, Evansville, and South Bend. Smaller branches may require an appointment — check the BMV website before you go.
You need to pass the General Knowledge test first. Then you can take the Doubles and Triples endorsement test on the same day if you're ready. The fee for the endorsement is $5 added to your CDL license fee. You'll also need a valid Medical Examiner's Certificate.
One thing that catches people off guard: Indiana requires you to have a CDL learner's permit for at least 14 days before you can take the skills test. So plan ahead. And bring your own vehicle for the skills portion — the BMV doesn't provide one. If you're testing with doubles or triples, make sure the equipment meets safety standards.
About the Indiana Doubles and Triples Test
If you're planning to pull doubles or triples on Indiana highways, you need this endorsement. The Indiana BMV requires it for any Class A CDL holder who wants to tow more than one trailer. We're talking about the trucks you see hauling grain on I-65 or moving freight through the I-80/94 Borman Expressway corridor. That traffic is no joke, and neither is this test.
Indiana's combination vehicle rules follow federal standards, but the BMV adds its own emphasis. Expect questions about coupling and uncoupling in all weather — especially winter. Indiana gets lake-effect snow off Lake Michigan that can dump a foot in a few hours. You need to know how to secure those trailers when the roads turn to ice.
The test has 20 multiple-choice questions. You need 80% to pass. That's 16 correct. The BMV gives you 25 minutes, but most people finish in 15 if they know the material. This practice test mirrors the real exam, so you'll know exactly what to expect before you walk into a BMV branch in Indianapolis, Evansville, or Fort Wayne.
You'll also learn about off-tracking — that's when your rear trailer cuts corners differently than your tractor. On Indiana's narrow two-lane roads in farm country, that can put you in the ditch if you're not careful. This test covers all of it.
