Sample Indiana CDL Test Questions - General Knowledge

Question 1

What does the term “black ice” describe?

  1. A Soft tar heated by the sun
  2. B An oil deposit on the pavement
  3. C Compacted snow covering the roadway
  4. D A thin, nearly transparent layer of ice

Correct answer: D – A thin, nearly transparent layer of ice

Black ice is a thin, clear layer of ice through which the pavement remains visible. Because it often resembles a wet road, it can be difficult to recognize before traction is lost. When the temperature is below freezing and the roadway appears wet, a driver should watch carefully for black ice.

Question 2

After applying the parking brake, how should you check whether it will hold the vehicle?

  1. A Leave the transmission in neutral and rev the engine
  2. B Select a low gear and gently pull against the brake
  3. C Release it and coast down a hill
  4. D Accelerate to at least 30 mph before applying it

Correct answer: B – Select a low gear and gently pull against the brake

Stop the vehicle and apply the parking brake before beginning the test. Place the transmission in a low gear and gently pull against the brake to confirm that it holds. This controlled procedure tests holding ability without applying the parking brake at road speed.

Question 3

Your signal is green, but stopped traffic leaves no room beyond the intersection. What should you do?

  1. A Wait before the intersection until there is room to clear it
  2. B Enter the intersection and wait for traffic to move
  3. C Sound the horn and proceed through the stopped traffic
  4. D Change lanes inside the intersection to get around the blockage

Correct answer: A – Wait before the intersection until there is room to clear it

Before entering an intersection, verify that it is clear and that there is enough space to proceed through it. Entering when traffic is backed up can leave your vehicle blocking cross traffic after the signal changes. Wait behind the intersection until sufficient room is available on the other side.

Question 4

Which speed-management practice is correct?

  1. A An empty truck always stops in less distance than a loaded truck
  2. B Doubling speed only doubles braking distance
  3. C Drive slowly enough to stop within the distance visible ahead
  4. D A fully alert driver may follow another vehicle closely

Correct answer: C – Drive slowly enough to stop within the distance visible ahead

Your speed should permit you to stop within the distance you can see ahead. Fog, rain, darkness, curves, and other visibility restrictions may require a substantial speed reduction. Doubling speed can make braking distance about four times longer, and empty trucks may need more stopping distance because they have less traction.

Question 5

For safer cargo balance, the heaviest items should generally be placed below lighter items.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Heavy cargo should be placed beneath lighter cargo so the load’s center of gravity remains as low as possible. A high center of gravity increases the likelihood of a rollover, especially during curves or sudden steering. Cargo must also be properly distributed and secured against movement.

Question 6

What is the primary benefit of an antilock braking system (ABS)?

  1. A It permits higher speeds and shorter following distances
  2. B It prevents every type of turning skid
  3. C It guarantees a shorter stopping distance
  4. D It helps prevent wheel lockup and maintain control during braking

Correct answer: D – It helps prevent wheel lockup and maintain control during braking

ABS detects when wheels are about to lock and adjusts braking pressure to help the driver maintain control. The Indiana CDL manual explains that ABS may allow you to steer around an obstacle while braking. It does not always shorten stopping distance, prevent every skid, or compensate for defective brakes or unsafe driving.
