Free Rhode Island CDL practice test online
Take a free Rhode Island CDL practice exam online with clear explanations—no sign-up. Coverage includes general knowledge, vehicle systems, combination vehicles, cargo, and endorsements. Then verify current requirements with Rhode Island Division of Motor Vehicles.
CDL knowledge tests are federally regulated, so the passing score in Rhode Island is the same as everywhere else: 80% correct on every knowledge test. You must also hold a commercial learner’s permit for 14 days before the skills test.

Requirements before you test
Rhode Island CDL test requirements
Commercial licensing is largely federal. Any figure above credited to a 49 CFR section applies in every state — see 49 CFR 383.135(a)(1) and 49 CFR 383.25(e). A figure credited to Rhode Island Division of Motor Vehicles is Rhode Island’s own, and may be stricter than the federal floor. Test length, fees, and scheduling are set by Rhode Island Division of Motor Vehicles (official source).
Entry-Level Driver Training comes first
Since February 7, 2022, a new Class A or Class B CDL, a class upgrade, or a first passenger, school bus, or hazardous materials endorsement requires training from a provider on the FMCSA Training Provider Registry (49 CFR 380.600). Practice questions are study material and do not satisfy that requirement.
FMCSA Training Provider RegistryYou need a Rhode Island licence first
A commercial learner’s permit only counts if you already hold an ordinary licence from the same state (49 CFR 383.25(a)(2)). The Rhode Island non-commercial knowledge test runs 40 questions and needs 28 correct, with permits issued from age 16.

5 Rhode Island CDL practice questions
Try these Rhode Island sample questions now — each shows the correct answer with a plain-language explanation and a source section. The full 600-question bank is in the practice run.
1. A placarded vehicle must normally display identical placards on:
- AThe driver’s door only
- BThe rear only
- Front, rear, and both sides
- DThe roof only
Answer: Front, rear, and both sides. Four-side visibility lets responders and the public identify the hazard from any approach.

2. If hydraulic brakes fail, pumping the brake pedal may:
- ADamage ABS permanently always
- Generate enough pressure to help stop the vehicle
- CFill the air tanks
- DRelease spring brakes
Answer: Generate enough pressure to help stop the vehicle. Also downshift and carefully use the parking/emergency brake while modulating to avoid lockup.

3. In a doubles combination, the heaviest trailer should be placed:
- AOn the converter dolly
- BWherever loading is quickest
- CAt the rear of the combination
- Directly behind the tractor
Answer: Directly behind the tractor. Putting the heavy trailer first improves stability and traction. A heavy rear trailer amplifies swing and raises rollover risk.

4. Compared with climbing the same hill, modern fuel-efficient trucks often need:
- ANo engine braking
- BA higher gear going downhill
- A lower gear going downhill than was needed to climb
- DNeutral on every downgrade
Answer: A lower gear going downhill than was needed to climb. Less friction and air drag mean less hold-back on descents, so drivers may need a lower gear down than up.

5. Longer combination vehicles offtrack more, so in turns the rear of the last trailer:
- Takes a shorter inside path you must allow for
- BNever leaves the lane center
- CTracks exactly on the steer-tire path
- DFollows a wider outside path than the tractor
Answer: Takes a shorter inside path you must allow for. Plan turns so the inside rear path clears curbs and vehicles. Longer combinations need more space.

CDL knowledge areas
Classes and endorsements, organized.
Each area below scopes the reviewed question bank to one knowledge test. The material is federal, so it applies in Rhode Island just like everywhere else — the endorsement guide explains how the codes fit together.
