Sample Michigan CDL Test Questions - General Knowledge

Question 1

What should you do if another driver is following your commercial vehicle too closely?

  1. A Increase the following distance ahead of your vehicle
  2. B Flash the brake lights repeatedly
  3. C Speed up to create distance behind you
  4. D Wave the other driver around immediately

Correct answer: A – Increase the following distance ahead of your vehicle

Increase the space between your vehicle and the traffic ahead when you are being tailgated. This extra room reduces the likelihood that you will need to brake or turn suddenly and gives the following driver more opportunity to pass. Avoid speeding up, flashing the brake lights, or making quick changes.

Question 2

According to the CDL manual, crashes involving people who drink alcohol result in more than approximately how many deaths each year?

  1. A 2,000
  2. B 20,000
  3. C 200,000
  4. D All traffic deaths

Correct answer: B – 20,000

The Michigan CDL manual states that people who drink alcohol are involved in traffic crashes resulting in more than 20,000 deaths each year. Alcohol impairs coordination, reaction time, depth perception, night vision, judgment, and inhibition. These effects increase crash risk even before a driver appears obviously intoxicated.

Question 3

Which two indicators can tell you when to shift a manual-transmission commercial vehicle?

  1. A Engine sound and coolant temperature
  2. B Engine speed and road speed
  3. C Time in the current gear and clutch pressure
  4. D Clutch resistance and falling oil pressure

Correct answer: B – Engine speed and road speed

Engine rpm and road speed are the two primary indicators for timing a shift. Learn the vehicle’s recommended operating rpm range and monitor the tachometer for the proper shift point. You can also learn the road-speed range for each gear and use the speedometer to determine when to shift.

Question 4

To reduce glare from oncoming headlights at night, where should you direct your vision?

  1. A Slightly right, toward the right lane or edge marking
  2. B Toward the left edge of the roadway
  3. C At the roadway centerline
  4. D Directly into the approaching headlights

Correct answer: A – Slightly right, toward the right lane or edge marking

The Michigan commercial driving manual advises against looking directly at an approaching vehicle’s lights. Instead, look slightly right toward a right-lane or edge marking, if one is available. This reduces the effect of glare while allowing you to continue tracking the roadway.

Question 5

What does the abbreviation “GVW” stand for?

  1. A Government vehicle weight
  2. B Gross variable weight
  3. C General vehicle width
  4. D Gross vehicle weight

Correct answer: D – Gross vehicle weight

GVW stands for gross vehicle weight. In Michigan CDL terminology, do not confuse GVW with GVWR, which stands for gross vehicle weight rating and refers to a manufacturer-specified weight rating.

Question 6

What is the most important purpose of inspecting a commercial vehicle before driving?

  1. A To determine whether more cargo will fit
  2. B To confirm that the vehicle is safe to operate
  3. C To increase the recorded on-duty time
  4. D To estimate the trip’s fuel cost

Correct answer: B – To confirm that the vehicle is safe to operate

The Michigan CDL manual identifies safety as the most important reason for inspecting a vehicle. Finding a defect before driving may prevent a roadside breakdown or a crash. The inspection protects the driver and other road users by identifying conditions that need repair before the vehicle is operated.
