Sample Colorado CDL Test Questions - General Knowledge

Question 1

A yellow diamond warning sign displays a black cross-shaped symbol. What does it warn you about?

This sign indicates _________________.
  1. A A pedestrian crosswalk ahead
  2. B A railroad crossing ahead
  3. C A rest area ahead
  4. D A crossroad intersection ahead

Correct answer: D – A crossroad intersection ahead

The cross-shaped symbol is the Cross Road warning sign. It alerts drivers that another roadway intersects the route ahead and that turning or entering traffic may be present. Approach at a speed that allows you to observe and respond to conditions at the intersection.

Question 2

Even when someone else loads the vehicle, the driver is responsible for which of the following?

  1. A Inspecting the cargo and identifying overloads or poor weight balance
  2. B Verifying that the cargo is secured and does not block the view ahead or to either side
  3. C Making sure the cargo does not prevent access to emergency equipment
  4. D All of the above

Correct answer: D – All of the above

The Colorado Commercial Driver License Manual assigns the driver responsibility for all three conditions. The driver must inspect the cargo, recognize overloading or poor balance, verify proper securement and visibility, and maintain access to emergency equipment. These responsibilities apply even when another person loaded and secured the cargo.

Question 3

If an emergency forces your vehicle off the roadway, which braking practice is recommended when possible?

  1. A Move every wheel off the pavement immediately
  2. B Apply the brakes hard as soon as you reach the shoulder
  3. C Avoid braking until about 20 mph, then brake very gently
  4. D Assume the shoulder cannot support a large vehicle

Correct answer: C – Avoid braking until about 20 mph, then brake very gently

If possible, let the vehicle slow to approximately 20 mph before using the brakes. Apply the brakes gently after reaching that speed because loose shoulder material can cause a skid. Keeping one set of wheels on the pavement, when possible, can also help maintain control.

Question 4

Which statement correctly describes an authorized federal inspection of a commercial motor vehicle?

  1. A The vehicle may be inspected, but it cannot be placed out of service
  2. B Inspection is permitted only at a state port of entry
  3. C Inspection is permitted only after a crash
  4. D The vehicle may be inspected and declared out of service if its condition or loading is unsafe

Correct answer: D – The vehicle may be inspected and declared out of service if its condition or loading is unsafe

Federal regulations authorize designated FMCSA personnel to inspect commercial motor vehicles in operation. Authorized personnel must declare a vehicle out of service when its mechanical condition or loading would likely cause an accident or breakdown. The vehicle may not be operated again until the repairs required by the out-of-service notice are completed.

Question 5

How many seconds ahead should a commercial driver generally scan while driving?

  1. A 1 to 2 seconds
  2. B 5 to 8 seconds
  3. C 12 to 15 seconds
  4. D 18 to 21 seconds

Correct answer: C – 12 to 15 seconds

The Colorado Commercial Driver License Manual recommends looking at least 12 to 15 seconds ahead. This provides time to identify traffic changes, hazards, and the space needed to stop or change lanes. Continue shifting your attention between near and distant conditions rather than staring only at the farthest point.

This sign indicates that the driver is ___________.
  1. A A yield sign
  2. B A stop sign
  3. C A traffic control signal
  4. D A railroad crossing

Correct answer: C – A traffic control signal

This is the Signal Ahead warning sign. It alerts drivers that they are approaching a traffic control signal, particularly when the signal may not be visible from a sufficient distance. Begin observing traffic conditions and be prepared to respond to the signal indication.
