Sample Rhode Island CDL Test Questions - General Knowledge

Question 1

Before inspecting beneath a tractor-trailer coupling, why should you shut off the engine and keep the ignition key with you?

  1. A To prevent the key from becoming dirty
  2. B To prevent another person from starting or moving the vehicle
  3. C To unlock the fifth-wheel release mechanism
  4. D To test the trailer’s electrical connection

Correct answer: B – To prevent another person from starting or moving the vehicle

Before inspecting the coupling, place the transmission in neutral, apply the parking brakes, shut off the engine, and take the key. Keeping the key with you prevents another person from starting or moving the vehicle while you are in a dangerous position. The vehicle must remain secured throughout the inspection.

Question 2

When cargo is stacked, the heaviest pieces should be placed beneath lighter pieces.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Heavy cargo placed high raises the vehicle’s center of gravity and increases the chance of a rollover, particularly in curves or during sudden steering. Distribute the load as low as possible by putting heavier pieces beneath lighter ones. The load must also be properly balanced and secured against movement.

Question 3

Which practice helps prevent overdriving your headlights at night?

  1. A Use high beams at all times
  2. B Look directly into approaching headlights
  3. C Keep your speed low enough to stop within the visible roadway
  4. D Turn instrument lights to their brightest setting

Correct answer: C – Keep your speed low enough to stop within the visible roadway

At night, drive slowly enough to stop within the distance illuminated ahead. Headlights provide less sight distance than daylight, and obstacles may not become visible until the vehicle is close to them. High beams cannot always be used, and looking at approaching headlights can impair your night vision.

Question 4

Which action helps you monitor the vehicle’s condition while driving?

  1. A Measure tire tread while the vehicle is moving
  2. B Open the brake-fluid reservoir during travel
  3. C Watch the dashboard gauges for signs of trouble
  4. D Inspect trailer connections without stopping

Correct answer: C – Watch the dashboard gauges for signs of trouble

During a trip, watch the vehicle’s gauges and instruments for unusual temperature, pressure, voltage, or air-pressure readings. Also use sight, hearing, smell, and feel to recognize possible trouble. When stopped, inspect critical components such as tires, wheels, brakes, lights, trailer connections, coupling devices, and cargo securement.

Question 5

In defensive commercial driving, what is a hazard?

  1. A Any road condition or road user that presents a possible danger
  2. B Only an object blocking the travel lane
  3. C Only a damaged section of pavement
  4. D An event involving chance rather than driving

Correct answer: A – Any road condition or road user that presents a possible danger

A hazard is any road condition or road user that could create danger. It may involve another driver, bicyclist, pedestrian, work zone, parked vehicle, or changing roadway condition. Recognizing hazards early gives you more time to slow down, change position, or prepare another safe response before an emergency develops.

Question 6

What does communicating your intentions mean in safe commercial driving?

  1. A Using a mobile telephone while driving
  2. B Applying the brakes repeatedly without a reason
  3. C Sounding the horn before every maneuver
  4. D Using signals to show what you plan to do

Correct answer: D – Using signals to show what you plan to do

Other road users cannot know your planned movement unless you communicate it. Use turn signals early and continuously before turns and lane changes, then cancel them after completing the maneuver. Brake lights and four-way flashers can also warn traffic behind you when you are slowing substantially or stopped.
