Sample Utah CDL Test Questions - General Knowledge

Question 1

Which activity is not one of the three segments of the CDL skills test?

  1. A A materials-handling test
  2. B A vehicle inspection
  3. C A basic vehicle-control test
  4. D An on-road driving test

Correct answer: A – A materials-handling test

Utah’s CDL skills test has three segments: vehicle inspection, basic vehicle control, and on-road driving. Applicants must take them in that order and pass each segment before advancing to the next. Operating warehouse or cargo-handling equipment is not a CDL skills-test segment.

Question 2

What information is a hazardous-materials placard intended to communicate?

  1. A The carrier’s safety rating
  2. B The vehicle’s maximum cargo weight
  3. C That the vehicle is transporting an oversize load
  4. D The hazard class of the material being transported

Correct answer: D – The hazard class of the material being transported

A hazardous-materials placard is a sign displayed on the outside of a vehicle to identify the cargo’s hazard class. Placards warn others about hazardous materials being transported. When placards are required, identical placards are displayed on the front, rear, and both sides so they are readable from every direction.

Question 3

In which of these situations is evacuation of a school bus mandatory?

  1. A The bus is on fire or threatened by fire
  2. B The bus is stalled on or next to a railroad-highway crossing
  3. C The bus faces an imminent danger of collision
  4. D All of these situations

Correct answer: D – All of these situations

All three listed conditions require evacuation. A school bus must be evacuated when it is on fire or threatened by fire, stalled on or adjacent to a railroad-highway crossing, or in imminent danger of a collision. A hazardous-materials spill requiring immediate evacuation is another mandatory condition identified in the handbook.

Question 4

Why is a damaged or leaking exhaust system especially dangerous?

  1. A Exhaust noise can permanently damage the driver’s hearing
  2. B Poisonous fumes can enter the cab or sleeper berth
  3. C Exhaust smoke can damage nearby vehicle paint
  4. D Exhaust smoke can make the vehicle exceed its axle-weight limit

Correct answer: B – Poisonous fumes can enter the cab or sleeper berth

A broken exhaust system can allow poisonous fumes into the cab or sleeper berth. Leaking carbon monoxide may cause drowsiness and can be fatal in sufficient amounts, particularly when ventilation is poor. Drivers should inspect for missing or damaged components, loose connections, and signs or sounds of exhaust leaks.

Question 5

Under Utah law, what is the minimum CDL disqualification for a first conviction of driving under the influence?

  1. A 6 months
  2. B 2 years
  3. C 1 year
  4. D 3 years

Correct answer: C – 1 year

A first qualifying conviction results in disqualification from driving a commercial motor vehicle for not less than one year. Covered offenses include driving while impaired or under the influence and operating a commercial vehicle with an alcohol concentration of .04 or more. Refusing a required chemical test also carries the one-year minimum. The minimum becomes three years if the violation occurs while transporting placarded hazardous material.

Question 6

What is a likely result when too little cargo weight rests on the front axle?

  1. A Reduced steering traction
  2. B Automatic damage to the drive-axle tires
  3. C Improved steering and handling
  4. D All of these results

Correct answer: A – Reduced steering traction

Shifting too much cargo weight toward the rear can leave the front axle underloaded. With insufficient weight on the steering axle, the front tires have less traction and the vehicle may not steer safely. Cargo should be balanced without exceeding axle, tire, suspension, or vehicle weight limits.
