How Many Questions Are on Rhode Island's CDL General Knowledge Test?
50 questions. That count is fixed by 49 CFR Part 383, the same across every state — Rhode Island administers the federal format at a single Cranston headquarters rather than at local branches.
One location for every CDL transaction
The federal government owns the question count and 80% threshold. Rhode Island's own arrangement charges $11.50 for the CDL application, plus $10 for each individual written knowledge test.
Unlike many license transactions available at local branch offices, every Rhode Island CDL transaction runs through the single DMV headquarters in Cranston.
A Class A applicant studies one more section
A Class B or C applicant studies Driving Safely, Transporting Cargo Safely, Air Brakes (if applicable), and Vehicle Inspection.
A Class A applicant studies all of that plus a Combination Vehicles section, since a Class A vehicle typically involves towing a trailer.
How our practice tests are structured
Our practice tests break results down by topic immediately, so a weak spot doesn't stay hidden inside an otherwise decent overall score.
Each question includes an explanation and a source reference, so you learn why an answer is correct instead of just memorizing a letter.
