Sample Nevada CDL Test Questions - General Knowledge

Question 1

A yellow diamond sign showing a black cross warns of what ahead?

This sign warns drivers to _____________.
  1. A A slow-vehicle route to the right
  2. B A detour beginning on the right
  3. C A location where every vehicle must stop
  4. D An intersection with possible entering or turning traffic

Correct answer: D – An intersection with possible entering or turning traffic

The crossroad warning sign indicates that an intersection is ahead and that traffic may enter or turn from either side. Nevada’s traffic-control system uses standardized intersection warning signs to help drivers recognize this possibility in advance. Reduce distractions, scan both sides of the roadway, and be ready to respond to traffic at the intersection.

Question 2

Which sequence correctly describes stab braking?

  1. A Apply light pressure and never allow the wheels to lock
  2. B Pump the brakes rapidly whether or not the wheels are turning
  3. C Hold the brakes fully applied after the wheels lock
  4. D Apply fully, release when the wheels lock, and reapply fully when they roll again

Correct answer: D – Apply fully, release when the wheels lock, and reapply fully when they roll again

With stab braking, apply the brakes fully and release them if the wheels lock. When the wheels begin rolling again, apply the brakes fully once more. Reapplying before wheel rotation resumes can prevent the vehicle from straightening. This method differs from controlled braking, which uses the greatest braking force possible without locking the wheels.

Question 3

Which conditions are tire problems that should be found during a vehicle inspection?

  1. A Excessive or insufficient air pressure
  2. B Abnormal wear or tread separation
  3. C Cuts or other visible damage
  4. D All of these conditions

Correct answer: D – All of these conditions

Commercial-vehicle tires should be checked for correct air pressure, adequate tread, abnormal wear, cuts, and tread separation. Other concerns include damaged valve stems, mismatched tires, and dual tires touching each other. Detecting these defects during an inspection can help prevent a roadside breakdown or loss of vehicle control.

Question 4

A Nevada CDL holder has no hazardous materials endorsement. Which shipment may the driver transport?

  1. A A nonplacarded shipment containing no listed select agent or toxin
  2. B Any shipment carried in a vehicle rated at 26,001 pounds or more
  3. C Any shipment that remains within the state
  4. D A placarded shipment if an endorsed passenger rides along

Correct answer: A – A nonplacarded shipment containing no listed select agent or toxin

An H endorsement is required to operate a commercial motor vehicle used to transport hazardous materials as defined in 49 CFR § 383.5. That definition includes materials requiring placards and any quantity of a listed select agent or toxin. A nonplacarded shipment outside the select-agent or toxin category does not require the endorsement based solely on its hazardous-material status.

Question 5

What is the primary purpose of hazardous-material placards?

  1. A To warn others and identify the cargo’s hazard class
  2. B To improve the vehicle’s braking performance
  3. C To identify an oversize or wide load
  4. D To display the motor carrier’s decorative markings

Correct answer: A – To warn others and identify the cargo’s hazard class

Placards are exterior signs that warn other road users and emergency personnel about hazardous materials. Their colors, symbols, and numbers communicate the hazard class or specific material being transported. Placards must be positioned so that the required hazard information can be read from the appropriate directions around the vehicle.

Question 6

It is safe to remove the radiator cap while the pressurized cooling system is still hot.

  1. A True
  2. B False

Correct answer: B – False

Never remove a radiator cap or another part of a pressurized cooling system until the system has cooled. Steam and boiling coolant can escape under pressure and cause severe burns. When coolant must be added directly, shut off the engine, allow it to cool, protect your hands, and release the cap slowly.
