Sample Nevada CDL Test Questions - General Knowledge

Question 1

Which practices can help a commercial driver avoid aggressive driving?

  1. A Give other drivers the benefit of the doubt
  2. B Slow down and maintain reasonable following distance
  3. C Drive cautiously and courteously
  4. D All of these practices

Correct answer: D – All of these practices

Avoiding aggressive driving requires both a calm attitude and safe driving habits. Allow for delays, give other drivers the benefit of the doubt, and maintain reasonable speed and following distance. Courteous behavior and avoiding hostile gestures can prevent an irritating traffic situation from escalating into a dangerous confrontation.

Question 2

During a walk-around inspection, what should you check wheel bearing seals for?

  1. A Paint discoloration
  2. B Leakage
  3. C Tread depth
  4. D Brake adjustment

Correct answer: B – Leakage

Wheel bearing seals should be inspected for signs of leakage. A leaking seal can allow lubricant to escape and may indicate a wheel-end problem requiring attention. During the same walk-around, also inspect the rims, tires, lug components, and nearby suspension parts, but those checks do not replace checking the seals themselves.

Question 3

What does a rectangular white sign reading “DO NOT PASS” require?

This sign indicates that the driver should _____________.
  1. A Pass only when operating behind schedule
  2. B Do not pass another motor vehicle while the restriction applies
  3. C Prepare for a mandatory stop ahead
  4. D Complete every pass and return right immediately

Correct answer: B – Do not pass another motor vehicle while the restriction applies

The DO NOT PASS sign emphasizes a restriction against overtaking within a no-passing zone. In Nevada, drivers must obey the directions of clearly visible official traffic-control devices. Do not begin a pass of another motor vehicle where the restriction applies; limited visibility or another roadway condition may make overtaking inappropriate there.

Question 4

A blue highway service sign displaying a fuel-pump symbol indicates what?

  1. A Fuel service is available
  2. B Road construction is ahead
  3. C Traffic must follow a detour
  4. D All of these conditions

Correct answer: A – Fuel service is available

Blue general-service signs direct road users to facilities such as gas, food, lodging, camping, hospitals, and tourist information. A fuel-pump symbol specifically identifies available fuel service. Construction and detour information generally uses temporary traffic-control signs rather than blue service signs.

Question 5

Which statement correctly describes downshifting for a curve?

  1. A Select the proper lower gear before entering the curve
  2. B Wait until the vehicle begins descending the next grade
  3. C Shift after entering the curve
  4. D Shift only after the curve is completed

Correct answer: A – Select the proper lower gear before entering the curve

Slow to a safe speed and select the proper gear before entering a curve. Entering in the correct gear allows some power to be applied through the turn, helping the vehicle remain stable. Braking or shifting after entering the curve can interfere with smooth vehicle control when traction and stability are especially important.

Question 6

Which equipment combination is required on most truck, truck-tractor, and bus power units?

  1. A A flashlight, tire gauge, and tire-sealant kit
  2. B A first-aid kit, gauze, and pain reliever
  3. C A properly rated fire extinguisher and required warning devices
  4. D A mobile phone, wheel chock, and portable hazard lamp

Correct answer: C – A properly rated fire extinguisher and required warning devices

Covered power units operating in Nevada must carry a properly rated fire extinguisher and approved warning devices for stopped vehicles. The extinguisher must be charged, accessible, and securely mounted. Three bidirectional reflective triangles are an accepted warning-device option; fusees may be allowed in some operations, but flame-producing devices are prohibited with specified hazardous cargoes and fuel systems.
