Sample Michigan CDL Test Questions - General Knowledge

Question 1

When backing a commercial vehicle, which direction should you favor when you can choose the side of the turn?

  1. A Toward the driver’s side whenever possible
  2. B Toward the passenger side whenever possible

Correct answer: A – Toward the driver’s side whenever possible

Michigan’s CDL manual recommends backing and turning toward the driver’s side whenever possible. This position gives the driver a better view of the vehicle’s rear by looking through the side window and using the mirrors. Back slowly, check the path beforehand, and use a helper when available.

Question 2

According to the CDL manual, what proportion of truck-driver crash deaths result from truck rollovers?

  1. A About 10%
  2. B About 20%
  3. C More than half
  4. D All of them

Correct answer: C – More than half

The CDL manual states that rollovers account for more than half of truck-driver deaths in crashes. A high center of gravity increases rollover risk, particularly when cargo is stacked high or placed off-center. Keeping the load low and centered and reducing speed through turns help limit this risk.

Question 3

How does a bridge formula generally affect allowable axle weight when axles are closer together?

  1. A It permits more axle weight
  2. B It permits less axle weight
  3. C It allows the same weight at every spacing
  4. D It converts GVWR into GCW

Correct answer: B – It permits less axle weight

Michigan’s CDL manual explains that a bridge formula permits less maximum axle weight when axles are closer together. Closely spaced axles concentrate their load on a smaller portion of a bridge. The formula limits that concentration to help prevent bridges and roadways from being overloaded.

Question 4

When can rainfall make the pavement especially slippery?

  1. A Immediately after the rain begins
  2. B Only during a heavy downpour
  3. C After several hours of steady rain
  4. D Only during a light drizzle

Correct answer: A – Immediately after the rain begins

Pavement can be especially slippery just after rain begins. Water mixes with oil and other residue left on the road, reducing available traction. Continued rainfall may eventually wash much of that oil away, but drivers should reduce speed and allow additional stopping distance whenever the road is wet.

Question 5

Why should you plan a response as soon as you recognize a hazard?

  1. A To guarantee that the hazard will disappear
  2. B To give yourself more time to act
  3. C To reduce the time available for a response
  4. D Because every hazard becomes an emergency

Correct answer: B – To give yourself more time to act

A hazard may develop into an emergency, so identifying it early gives you time to plan an escape or response. Consider what could happen and decide how you would react. Not every hazard becomes an emergency, but advance planning helps prevent sudden, poorly considered actions.

Question 6

On dry, level pavement with no rollback risk, which actions are normally unnecessary when starting a manual-transmission CMV?

  1. A Releasing the clutch abruptly while pressing the accelerator
  2. B Using the parking brake to prevent rollback
  3. C Both A and B

Correct answer: C – Both A and B

A commercial vehicle should be accelerated smoothly and gradually rather than by abruptly releasing the clutch. The parking brake should be used whenever necessary to prevent the vehicle from rolling backward. On level pavement where rollback is not a concern, neither rough acceleration nor use of the parking brake for rollback control is normally needed.
