Sample Colorado CDL Test Questions - General Knowledge

Question 1

In Colorado, when no traffic signal is operating, to whom must a driver yield at a crosswalk?

  1. A A pedestrian on the driver’s half of the roadway or approaching closely from the opposite half
  2. B A motorcyclist waiting at a side street
  3. C A passenger car leaving a driveway
  4. D A bicyclist riding outside the crosswalk and bicycle lane

Correct answer: A – A pedestrian on the driver’s half of the roadway or approaching closely from the opposite half

When signals are absent or not operating, a driver must yield, slowing or stopping if necessary, to a pedestrian in a crosswalk on the vehicle’s half of the roadway or approaching closely enough from the opposite half to be in danger. A pedestrian may not suddenly enter the path of a vehicle that is too close to stop safely.

Question 2

What is true when a substance affects a CMV driver enough to prevent safe vehicle operation?

  1. A Its use is allowed whenever a doctor prescribed it
  2. B Operating the CMV while affected is prohibited
  3. C Its use is allowed if it is an over-the-counter medicine
  4. D A small amount of alcohol can offset its effects

Correct answer: B – Operating the CMV while affected is prohibited

Federal motor-carrier rules prohibit a driver from being on duty under the influence of any substance to a degree that prevents safe vehicle operation. The medical-use exception applies only when a licensed medical practitioner has advised the driver that the substance will not affect safe driving. A prescription alone does not establish that the driver may safely operate a CMV.

Question 3

A 40-foot commercial vehicle is traveling at 50 mph. What following interval should the driver maintain under normal conditions?

  1. A 3 seconds
  2. B 4 seconds
  3. C 7 seconds
  4. D At least 5 seconds

Correct answer: D – At least 5 seconds

The recommended interval is one second for each 10 feet of vehicle length when traveling below 40 mph. At speeds above 40 mph, add one more second. A 40-foot vehicle requires four seconds for its length plus one additional second at 50 mph, for a total of at least five seconds.

Question 4

Before starting a CMV trip in Colorado, which action best helps prevent distracted driving?

  1. A Eat a large meal immediately before driving
  2. B Rely on coffee to maintain attention
  3. C Learn the vehicle’s features and adjust mirrors, controls, and radio settings before moving
  4. D Keep a phone available for reading messages while driving

Correct answer: C – Learn the vehicle’s features and adjust mirrors, controls, and radio settings before moving

A driver should eliminate or reduce in-vehicle distractions before beginning the trip. This includes becoming familiar with the vehicle, adjusting mirrors and controls, programming navigation or radio settings, and securing loose objects. Texting, reading, eating, and making adjustments while moving take attention away from safe vehicle operation.

Question 5

Which listed item is part of the suspension system?

  1. A Tie rod
  2. B Drag link
  3. C Pitman arm
  4. D None of the above

Correct answer: D – None of the above

A tie rod, drag link, and pitman arm are steering-system components, not suspension parts. Suspension components include springs, spring hangers, shackles, torque rods, U-bolts, and shock absorbers. The suspension supports the vehicle and load while keeping the axles properly positioned.

Question 6

During a kingpin, apron, and coupling-gap inspection, which condition should be verified?

  1. A The kingpin is straight and undamaged
  2. B The visible apron has no bends, cracks, or breaks
  3. C The trailer rests flat on the fifth-wheel skid plate without a gap
  4. D All of the above

Correct answer: D – All of the above

Colorado’s CDL vehicle inspection procedure requires all three checks. The kingpin must be properly positioned and free of bending, damage, or excessive wear, and the visible apron must not be bent, cracked, or broken. The apron must also rest flat against the fifth-wheel skid plate with no space between them.
