Sample Oregon CDL Test Questions - General Knowledge

Question 1

What is the basic goal when distributing cargo weight?

  1. A Keep axle loading properly balanced
  2. B Place most of the weight at the front
  3. C Place most of the weight at the rear
  4. D Stack the heaviest cargo as high as possible

Correct answer: A – Keep axle loading properly balanced

Cargo should be distributed to maintain proper weight balance among the axles. Excessive steering-axle weight can cause hard steering, while too little front-axle weight can make safe steering difficult. Too little weight on the drive axles can also reduce traction and allow the drive wheels to spin.

Question 2

In Oregon, which operation is excepted from ordinary CDL requirements when all applicable conditions are met?

  1. A An emergency fire vehicle operated by a firefighter
  2. B An emergency vehicle operated by a qualified emergency service volunteer
  3. C A qualifying farm operation conducted under a farm endorsement
  4. D All of these

Correct answer: D – All of these

All three operations qualify under specific state provisions. Emergency fire vehicles operated by firefighters and emergency vehicles operated by qualified volunteers are excluded from the commercial motor vehicle definition. Farm endorsements authorize qualifying farm transportation, subject to conditions such as farmer control, eligible cargo and use within 150 miles of the farm.

Question 3

A front tire on a truck or truck tractor must have at least how much tread in a major groove?

  1. A 2/32 inch
  2. B 4/32 inch
  3. C 6/32 inch
  4. D 1/4 inch

Correct answer: B – 4/32 inch

The federal tire standard requires at least 4/32 inch of tread in a major groove on the front wheels of a bus, truck, or truck tractor. Most other tire positions require at least 2/32 inch. The front-tire measurement is not made at tie bars, humps, or fillets.

Question 4

Which condition is acceptable during an inspection of the brakes and suspension?

  1. A Brake shoes and pads are free of oil, grease, and brake fluid
  2. B A leaf spring has a missing leaf
  3. C A spring hanger is cracked
  4. D A brake shoe is dangerously thin

Correct answer: A – Brake shoes and pads are free of oil, grease, and brake fluid

Brake shoes and pads should not be contaminated with oil, grease, or brake fluid because contamination reduces usable friction. Missing or broken leaf-spring leaves can be dangerous, and cracked or broken spring hangers are suspension defects. Brake shoes that are dangerously thin, missing, or broken are also unacceptable.

Question 5

An empty truck generally has better braking performance than the same truck when loaded.

  1. A True
  2. B False

Correct answer: B – False

Empty trucks can require greater stopping distance because they have less traction. Heavy-vehicle brakes, tires, springs, and shock absorbers are designed to work best when the vehicle is loaded. Reduced traction also makes an empty or lightly loaded vehicle more likely to skid if the wheels lock.

Question 6

Removing the cargo from a commercial truck always shortens its stopping distance.

  1. A True
  2. B False

Correct answer: B – False

An empty truck does not automatically stop in a shorter distance. Empty vehicles have less traction, and commercial-vehicle braking and suspension systems are designed to perform best under load. The reduced traction can increase stopping distance and make wheel lockup or skidding more likely.
