Sample Indiana CDL Test Questions - General Knowledge

Question 1

Which driving actions can cause a commercial vehicle to skid?

  1. A Turning the steering wheel too sharply
  2. B Braking hard enough to lock the wheels
  3. C Driving too fast for conditions
  4. D All of the above

Correct answer: D – All of the above

A skid occurs when the tires lose their grip on the roadway. The Indiana CDL manual identifies over-braking, over-steering, over-acceleration, and excessive speed for conditions as causes. Hard braking can lock the wheels, while sharp steering can demand more traction than the tires have. Excessive speed contributes to many serious skids.

Question 2

Which items are among the limited hazardous-material exceptions that a passenger bus may transport under applicable conditions?

  1. A Small-arms ammunition
  2. B Emergency shipments of hospital supplies
  3. C Emergency shipments of drugs
  4. D All of the above

Correct answer: D – All of the above

Federal hazardous-materials regulations permit passenger-carrying vehicles to transport small-arms ammunition and emergency shipments of drugs, chemicals, and hospital supplies under applicable conditions. These are limited exceptions, not general authorization to carry hazardous materials. Additional quantity, packaging, location, and availability-of-other-transportation restrictions may apply.

Question 3

Before backing with a helper, which hand signal is most important for both of you to establish?

  1. A Move forward
  2. B Back straight
  3. C Turn toward the helper
  4. D Stop

Correct answer: D – Stop

Before backing, the driver and helper should agree on hand signals they both understand, especially a clear stop signal. The Indiana CDL manual directs the helper to remain near the rear where the driver can see them. If the helper disappears from view, the driver should stop backing until visual contact is restored.

Question 4

Which is the proper way to handle mobile-phone communications while operating a CMV?

  1. A Read messages only while traveling below 35 mph
  2. B Use compliant hands-free operation while driving, and stop safely off the highway before handheld use
  3. C Hold the phone in one hand while keeping the other on the wheel
  4. D Send messages while temporarily stopped in traffic

Correct answer: B – Use compliant hands-free operation while driving, and stop safely off the highway before handheld use

An Indiana CDL driver may not use a hand-held mobile telephone or text while driving a CMV. Federal rules include temporary stops for traffic or signals within the meaning of driving. A hands-free phone must be close enough to operate without unsafe reaching. Handheld use requires moving safely off the highway and stopping, except when necessary to contact law enforcement or emergency services.

Question 5

Which description best matches gross combination weight (GCW)?

  1. A The weight of the cargo and occupants only
  2. B The manufacturer’s maximum rating for the power unit
  3. C The actual weight of the trailer and its cargo only
  4. D The actual combined weight of the power unit, towed units, and their loads

Correct answer: D – The actual combined weight of the power unit, towed units, and their loads

Gross combination weight is the actual total weight of a combination vehicle, including the power unit, each towed unit, and the loads being carried. It should not be confused with gross combination weight rating, which is a maximum rated value determined under federal CDL definitions. The distinction is important when evaluating vehicle classification and weight limits.

Question 6

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

  1. A A posted clearance guarantees that every vehicle below that height will fit
  2. B Loading or unloading cargo can change the vehicle’s height
  3. C A tilted roadway is safest when you drive near the shoulder
  4. D A heavy vehicle will fit wherever a passenger car fits

Correct answer: B – Loading or unloading cargo can change the vehicle’s height

The height of some commercial vehicles changes with the load. The Indiana CDL manual notes that an empty cargo van may be higher than the same van when loaded. Posted clearance can also become inaccurate after repaving or an accumulation of packed snow. If adequate clearance is uncertain, proceed cautiously or choose another route.
