Sample Oregon CDL Test Questions - General Knowledge

Question 1

A reversing-curves warning sign shows the roadway bending first right and then left. What does it warn you about?

This sign warns drivers to _____________.
  1. A. A single curve to the right
  2. B. A sharp right turn followed by a stop
  3. C. A winding road with several curves
  4. D. Two successive curves, first right and then left

Correct answer: D. – Two successive curves, first right and then left

This warning sign indicates that the road ahead curves first to the right and then to the left. The Oregon manual identifies it as a reversing-curves sign. Reduce speed as conditions require and prepare to steer through both changes in direction.

Question 2

Before a helper guides you while backing, which hand signal is most important to establish?

  1. A. Pull forward
  2. B. Begin backing
  3. C. Turn toward me
  4. D. Stop

Correct answer: D. – Stop

Before backing, agree on hand signals that both you and the helper understand. The stop signal is the most important because it directs you to halt immediately when the path is unsafe or the helper needs to reposition. The helper should remain near the rear of the vehicle where you can see them.

Question 3

What happens when a commercial vehicle hydroplanes?

  1. A. The tires lose contact with the road and have little or no traction
  2. B. The steering wheel turns even though the vehicle remains straight
  3. C. The brakes apply without the driver pressing the pedal
  4. D. The suspension lifts the vehicle above standing water

Correct answer: A. – The tires lose contact with the road and have little or no traction

Hydroplaning occurs when tires ride on water or slush instead of maintaining contact with the road. With little or no traction, steering and braking may become ineffective. Standing water, low tire pressure and worn tread increase the risk, and hydroplaning can occur at speeds as low as 30 mph when enough water is present.

Question 4

Before making a permitted right turn on red in Oregon, what must a driver do?

  1. A. Enter the intersection before checking cross traffic
  2. B. Stop only when a pedestrian is visible
  3. C. Slow down without making a complete stop
  4. D. Come to a complete stop, then yield before turning

Correct answer: D. – Come to a complete stop, then yield before turning

Oregon law requires a driver facing a steady red signal to stop at the designated stopping point. A permitted right turn may then be made unless a sign or officer prohibits it, but the driver must first yield to traffic and pedestrians. Merely slowing down is not sufficient.

Question 5

During Step 4 of the seven-step vehicle inspection, which lights should you activate before leaving the cab?

  1. A. Parking lights and the right turn signal
  2. B. High beams and brake lights
  3. C. Clearance lights and the left turn signal
  4. D. Low-beam headlights and four-way emergency flashers

Correct answer: D. – Low-beam headlights and four-way emergency flashers

Set the parking brake, turn off the engine and take the key before leaving the cab. Turn on the low-beam headlights and four-way emergency flashers, then verify that they work. The procedure later calls for turning these off and activating the parking, clearance, marker, identification and turn-signal lights.

Question 6

What does a Two-Way Traffic Ahead warning sign mean?

This sign warns drivers to _____________.
  1. A. A two-way road crosses your road ahead
  2. B. The one-way road joins a two-way road, and you will face oncoming traffic
  3. C. The road ahead carries traffic in one direction only
  4. D. All traffic must turn at the next intersection

Correct answer: B. – The one-way road joins a two-way road, and you will face oncoming traffic

The sign warns that a one-way roadway is joining a two-way roadway. Drivers must be prepared to encounter traffic moving in the opposite direction. The Oregon manual calls this sign Two-Way Traffic Ahead and emphasizes that oncoming vehicles will be present.
