Free RI CDL Double/Triple Trailers Practice Test 2025

Want to pull doubles in Rhode Island? You must hold a Class A CDL and obtain a Double/Triple (T) endorsement on your CDL. (It’s also highly advisable to be fully qualified to operate vehicles with air brakes.) There aren’t many drivers with all these qualifications and skills. Hence, such drivers tend to be in high demand and earn higher salaries than drivers limited to single-trailer vehicles.

Rhode Island prohibits double trailers in urban areas and has relatively strict bridge weight regulations elsewhere, especially on I-95 and I-195. Triple trailers are prohibited statewide.

Still, several of the state’s key economic sectors use doubles for efficient transport. Retailers use doubles to supply stores with goods from distribution centers in Connecticut and Massachusetts. In the logistics sector, companies use doubles to transport cargo arriving at the Port of Providence (Provport). Double trailers are also used for parcel and Less-Than-Truckload (LTL) shipping. (Demand for parcel shipping is high because of the state’s proximity to the logistics hubs of Boston, Hartford, and New York City.) Finally, Rhode Island’s manufacturing sector, including aerospace, defense, and electronics, operates doubles to transport parts and raw materials.

To obtain the Double/Triple endorsement on your CDL, you must pass the official Double/Triple knowledge test. Among the topics covered are safe handling, air brakes on doubles and triples, coupling and uncoupling, emergency situations, pre-trip inspections, and state and federal regulations on doubles and triples. (No special skills test is required.)

This knowledge test is based on the official Rhode Island CDL manual (Rhode Island CDL Handbook 2025), especially Chapter 7: Doubles and Triples.
