Sample Oregon CDL Test Questions - General Knowledge

Question 1

  1. A. It is used only on vehicles without antilock brakes
  2. B. The brakes are applied firmly without locking the wheels
  3. C. The wheels are locked, released, and then locked again
  4. D. The brakes are held down after all wheels lock

Correct answer: B. – The brakes are applied firmly without locking the wheels

Question 2

What does a Double Arrow warning sign mean?

This sign indicates that _____________.
  1. A. Traffic must turn left
  2. B. Traffic must turn right
  3. C. Traffic may pass on either side of an island or obstruction
  4. D. The roadway is closed in both directions

Correct answer: C. – Traffic may pass on either side of an island or obstruction

A Double Arrow sign advises that traffic is permitted to pass on either side of an island, obstruction, or gore in the roadway. The separated traffic paths may later rejoin or proceed in different directions. It does not require a particular turn or indicate that the road is closed.

Question 3

About how long does a typical tractor-trailer need to clear a double railroad track?

  1. A. More than 13 seconds
  2. B. More than 14 seconds
  3. C. More than 15 seconds
  4. D. More than 16 seconds

Correct answer: C. – More than 15 seconds

A typical tractor-trailer takes more than 15 seconds to clear a double railroad track. It takes at least 14 seconds to clear a single track. Before entering a crossing, the driver must verify that traffic conditions allow the entire combination to cross without stopping on the tracks.

Question 4

A red rectangular sign displaying “WRONG WAY” indicates that:

This sign warns drivers that _________________.
  1. A. You are entering an expressway
  2. B. Heavy traffic is expected ahead
  3. C. You are traveling opposite the permitted direction of traffic
  4. D. You may continue if you proceed cautiously

Correct answer: C. – You are traveling opposite the permitted direction of traffic

The WRONG WAY sign is used to warn road users traveling against the permitted traffic flow. It commonly supplements a DO NOT ENTER sign near a one-way roadway or exit ramp. In Oregon, encountering this sign facing you indicates that continuing in the same direction would be a wrong-way movement.

Question 5

Which cargo-related condition must you verify when transporting a sealed load?

  1. A. Every item inside the container is tied down
  2. B. The contents match a physical count made by the driver
  3. C. The seal may be broken whenever an inspection is convenient
  4. D. Gross and axle weight limits are not exceeded

Correct answer: D. – Gross and axle weight limits are not exceeded

A driver cannot inspect the contents of a sealed load without breaking the seal. The driver should still verify that the vehicle does not exceed gross-weight or axle-weight limits. A seal does not excuse an overweight vehicle or eliminate the need to check the load’s effect on legal vehicle weight.

Question 6

How should hydraulic brakes be tested for leakage before driving?

  1. A. While moving, pump three times and hold firm pressure for five seconds
  2. B. While moving, pump five times and hold firm pressure for three seconds
  3. C. While stopped, pump three times and hold firm pressure for five seconds
  4. D. While stopped, pump five times and hold firm pressure for three seconds

Correct answer: C. – While stopped, pump three times and hold firm pressure for five seconds

With the vehicle stopped, pump the hydraulic brake pedal three times. Apply firm pressure and hold the pedal for five seconds. The pedal should remain in position; movement may indicate a leak or another brake-system problem that must be repaired before driving.
