Sample Arkansas CDL Test Questions - General Knowledge

Question 1

Which statement about a commercial vehicle's overhead clearance is correct?

  1. A A posted clearance guarantees that every vehicle will fit
  2. B The vehicle's height can change when its load changes
  3. C A tilting road surface requires driving closer to the shoulder
  4. D A loaded van is always higher than the same van when empty

Correct answer: B – The vehicle's height can change when its load changes

A vehicle's height may change with its load. For example, an empty cargo van may ride higher than the same van when loaded, making a previously cleared structure unsafe on a later trip. Drivers must verify adequate clearance and account for repaving, uneven surfaces, tilting, and unmarked overhead hazards.

Question 2

Before backing with a helper, which hand signal is most important to agree upon?

  1. A Slow down
  2. B Pull forward
  3. C Continue straight back
  4. D Stop

Correct answer: D – Stop

The driver and helper should agree on understandable hand signals before backing, especially a clear stop signal. The helper should remain near the rear of the vehicle where the driver can see them. If the helper disappears from view or gives the stop signal, the driver should stop the maneuver.

Question 3

What are the two trailer air lines on a combination vehicle called?

  1. A Service and emergency
  2. B Service and brake
  3. C Brake and reserve
  4. D Pressure and return

Correct answer: A – Service and emergency

Combination vehicles use a service line and an emergency line. The service line, also called the control or signal line, carries air controlled by the brake pedal or trailer hand valve. The emergency line, also called the supply line, supplies the trailer tanks and controls the trailer emergency brakes.

Question 4

Which group of items should be monitored or checked during a trip?

  1. A Gauges, exhaust stack, shock absorbers, frame, and fuel cap
  2. B Gauges, heater, horn, wipers, and interior trim
  3. C Gauges, brakes, lights, cargo securement, and coupling devices
  4. D Only tires and wheels at the end of the trip

Correct answer: C – Gauges, brakes, lights, cargo securement, and coupling devices

During a trip, watch the gauges and use sight, sound, smell, and touch to detect problems. At stops, check critical items such as brakes, lights and reflectors, cargo-securement devices, and trailer couplings. Tires, wheels, rims, and trailer brake and electrical connections should also receive attention.

Question 5

If a hydraulic brake system loses pressure, which response is appropriate?

  1. A Downshift to help reduce speed
  2. B Pump the brake pedal to try to restore pressure
  3. C Control the parking brake while searching for an escape route
  4. D All of the above

Correct answer: D – All of the above

Downshifting can use the engine to help slow the vehicle, and pumping the pedal may generate enough hydraulic pressure for some braking. The separate parking brake may also be used with controlled pressure to avoid locking the wheels. While slowing, the driver should look for the least hazardous escape route available.

Question 6

How many numbered hazardous-material classes are used in the transportation system?

  1. A 3
  2. B 6
  3. C 9
  4. D 12

Correct answer: C – 9

Federal hazardous-materials regulations use nine numbered hazard classes, Classes 1 through 9. They cover explosives, gases, flammable liquids, flammable solids, oxidizers and organic peroxides, toxic and infectious materials, radioactive materials, corrosives, and miscellaneous hazardous materials. The Arkansas CDL manual presents the same nine-class framework.
