Sample Rhode Island CDL Test Questions - General Knowledge

Question 1

Which statement about tires in very hot weather is correct?

  1. A Release air whenever a tire becomes warm
  2. B Tire pressure does not need to be checked during an inspection
  3. C Tire air pressure rises as temperature increases
  4. D Hot tires should be cooled by driving faster

Correct answer: C – Tire air pressure rises as temperature increases

The Rhode Island CDL manual notes that tire pressure increases with temperature. Do not release air merely because a tire is hot, because its pressure may become too low after it cools. During very hot weather, inspect tires every two hours or 100 miles. If a tire is too hot to touch, remain stopped until it cools.

Question 2

Which brake defects require attention during a vehicle inspection?

  1. A Cracks in a brake drum
  2. B Oil, grease, or brake fluid on a shoe or pad
  3. C Missing, broken, or dangerously thin friction material
  4. D All of these

Correct answer: D – All of these

Inspect brake drums for cracks and examine shoes or pads for contamination by oil, grease, or brake fluid. Friction material must not be missing, broken, or worn dangerously thin. Any of these defects may reduce braking performance and must be addressed before the vehicle is operated.

Question 3

If an emergency forces your commercial vehicle onto the shoulder, how should you brake?

  1. A Move every wheel off the pavement immediately
  2. B Apply the brakes as hard as possible when leaving the road
  3. C If possible, wait until about 20 mph, then brake very gently
  4. D Accelerate until you reach a paved area

Correct answer: C – If possible, wait until about 20 mph, then brake very gently

If possible, avoid braking until the vehicle has slowed to about 20 mph. Then apply the brakes very gently because a loose shoulder can provide less traction than the pavement. Keep one set of wheels on the pavement when possible, and remain on a clear shoulder until you can stop safely.

Question 4

Which group belongs in the commercial-vehicle emergency-equipment inspection?

  1. A Flashlight, tire gauge, and inflation sealant
  2. B First-aid gauze, pain reliever, and water
  3. C Fire extinguisher, warning devices, and spare fuses if used or identification of circuit breakers
  4. D Cell phone, wheel chock, and portable work light

Correct answer: C – Fire extinguisher, warning devices, and spare fuses if used or identification of circuit breakers

The inspection includes a properly charged and secured fire extinguisher, required warning devices, and spare fuses if the vehicle uses them; otherwise, the driver identifies the circuit breakers. Federal equipment rules require covered power units to carry a suitable extinguisher and warning devices. Rhode Island’s current CDL manual retains the fuse-or-circuit-breaker check in its vehicle-inspection procedure.

Question 5

On a Rhode Island roadway, what does a yellow right-curve warning sign with a “40 MPH” plaque indicate?

This sign warns drivers to _______________.
  1. A Vehicles under 40 mph must stay in the right lane
  2. B Drivers must maintain a minimum speed of 40 mph
  3. C The recommended operating speed for the curve is 40 mph
  4. D Drivers should exceed 40 mph while traveling through the curve

Correct answer: C – The recommended operating speed for the curve is 40 mph

An advisory-speed plaque supplements a warning sign and states the recommended operating speed for the condition ahead. It is not a minimum speed or a regulatory speed-limit sign. The driver must still consider vehicle stability, cargo, visibility, weather, and road conditions and use a lower speed when necessary to negotiate the curve safely.

Question 6

Below a .04 BAC, what alcohol finding still requires a 24-hour out-of-service order?

  1. A A BAC of exactly .04
  2. B Any detectable amount of alcohol
  3. C A BAC of .05 or higher
  4. D A BAC of .08 or higher

Correct answer: B – Any detectable amount of alcohol

Federal regulation prohibits a CMV driver from operating or being on duty with a measured alcohol concentration or detected presence of alcohol. A measurable amount below .04 requires a 24-hour out-of-service order. Rhode Island’s CDL manual also states this rule. A BAC of .04 or higher carries separate CDL disqualification consequences in addition to removal from service.
