📘 Study Tips & State Info
Connecticut examiners focus on the exact coupling sequence — they want the steps in order, from backing under the trailer to locking the fifth wheel. Don't skip the part about checking the air lines and glad hands for damage. In winter, those connections freeze up, and a proper inspection catches that. The CT CDL manual has a checklist on page 42 (or whatever the actual page is — memorize it).
Practice the off-tracking questions by visualizing a turn on I-84 eastbound at exit 25 in Waterbury. That ramp is a tight right-hander. The manual says longer trailers cut corners sharper — apply that to a real road you know. Also, wind questions come up a lot. Connecticut gets gusty conditions from coastal storms. Know how to reduce speed when your trailer starts to sway. The DMV doesn't test on the Merritt Parkway because doubles are banned there, but the principles apply everywhere.
One tip from years of watching students: don't rush the inspection questions. The pre-trip for doubles includes checking the dolly tires, the pintle hook, and the safety chains. If you skip a step in your head on the written test, you'll likely miss the question. Slow down, read each answer carefully.
You take the Connecticut Doubles and Triples test at any of the full-service DMV offices that offer CDL written exams. The main locations are Wethershead, Hamden, Norwalk, Waterbury, and New Britain. You don't need an appointment for the written test — walk-ins are accepted, but arrive early because CDL testing lines can be long, especially Monday mornings.
The test fee is included in your CDL permit application — currently $30 for the permit, which covers all written tests you take on that visit. If you fail the Doubles and Triples test, you can retake it the same day? Actually, Connecticut requires a 24-hour wait between retakes. Bring your valid Medical Examiner's Certificate and your Social Security card. Out-of-state applicants need to provide proof of Connecticut residency.
Connecticut follows the federal standard for this endorsement: 20 questions, 80% to pass. The test is available in English and Spanish. If you need a translator, you can bring one, but they must sign an affidavit. The DMV's CDL unit in Wethershead handles all special cases — call them if you're unsure about your eligibility.
About the Connecticut Doubles and Triples Test
Connecticut's highway system wasn't built for long combination vehicles. I-84 through Waterbury has tight curves and steep grades that'll test your coupling and braking skills. I-95 south of New Haven stacks up with traffic and narrow lanes. That's why the Connecticut Doubles and Triples test isn't just a formality — it's about keeping you and everyone else safe when you're pulling 100 feet of trailer through rush hour.
The test covers coupling and uncoupling step by step. Connecticut examiners want to know you can hook up a set of doubles on a wet lot in January without skipping a step. They'll ask about off-tracking — because when you turn off I-91 onto Route 34 in New Haven, you need to know where your rear axle is going. Trailer stability matters here, especially when a Nor'easter kicks up crosswinds on the Merritt Parkway (though doubles aren't allowed there, the principle applies).
You'll also face questions about braking distances with extra trailers, the dangers of rearward amplification (the crack-the-whip effect), and how to inspect a dolly. Connecticut's distribution centers — like the Amazon facility in Windsor Locks and the rail yards in Waterbury — mean you'll see plenty of doubles on the road. Passing this test is your ticket to those jobs.
The test is 20 multiple-choice questions. You need 80% — that's 16 correct. The Connecticut DMV gives you 25 minutes. Our practice test mimics that exact timing so you're ready for the real thing.
