Sample Maine CDL Test Questions - General Knowledge

Question 1

Which description best identifies black ice?

  1. A A thin, nearly transparent ice layer through which the pavement remains visible
  2. B Dark-colored ice piled along the shoulder
  3. C Ice that has almost completely melted and is no longer slippery
  4. D A harmless surface stain caused by road salt

Correct answer: A – A thin, nearly transparent ice layer through which the pavement remains visible

Black ice is a thin, clear layer through which the road surface can still be seen. Because it often makes pavement look wet rather than frozen, it can be difficult to recognize. When the temperature is below freezing and the roadway appears wet, reduce speed and watch carefully for black ice.

Question 2

An unblocked article is 8 feet long and is not otherwise prevented from moving forward. What is the minimum number of tie-downs required?

  1. A 1
  2. B 2
  3. C 3
  4. D 4

Correct answer: B – 2

The federal cargo-securement rule requires at least two tie-downs for an unblocked article that is longer than 5 feet but no longer than 10 feet, regardless of weight. The Maine manual gives similar general instruction about using sufficient tie-downs, but the exact minimum can depend on the article’s length, weight, blocking, and any commodity-specific requirements.

Question 3

Before backing with a helper, which hand signal is most important for both of you to establish?

  1. A Pull forward
  2. B Turn toward the passenger side
  3. C Continue backing
  4. D Stop

Correct answer: D – Stop

Before backing begins, the driver and helper should agree on signals they both clearly understand, especially the signal for stop. The helper should remain where the driver can see them and should monitor areas hidden by the vehicle. If the helper disappears from view or gives the stop signal, stop the vehicle immediately.

Question 4

Water should not be used on which of these fires?

  1. A An electrical fire only
  2. B A gasoline fire only
  3. C Neither an electrical fire nor a gasoline fire
  4. D Both an electrical fire and a gasoline fire

Correct answer: C – Neither an electrical fire nor a gasoline fire

Do not use water on electrical or gasoline fires. Water can conduct electricity and expose you to shock, while gasoline can float on water and allow the flames to spread. Use an extinguisher rated for the fire involved. If you are uncertain—especially with hazardous materials—wait for trained firefighters.

Question 5

Which item is not among the emergency-equipment options listed for a typical commercial power unit?

  1. A A properly rated fire extinguisher
  2. B Three compliant reflective warning triangles
  3. C A first-aid kit
  4. D At least six compliant fusees as an allowed warning-device option

Correct answer: C – A first-aid kit

The federal emergency-equipment rule requires a properly rated fire extinguisher and an approved warning-device option, such as three reflective triangles or at least six fusees. It does not list a first-aid kit as standard required equipment for these power units. Flame-producing warning devices are prohibited on certain hazardous-material and compressed-gas-fueled vehicles.

Source: 49 CFR § 393.95(a), (f), (g) – Emergency equipment on all power units

Question 6

What does gross combination weight (GCW) describe?

  1. A The weight of the cargo and vehicle occupants only
  2. B The manufacturer’s maximum rated weight for a combination
  3. C The actual weight of the trailer and cargo only
  4. D The actual total weight of the power unit, trailer or trailers, and cargo

Correct answer: D – The actual total weight of the power unit, trailer or trailers, and cargo

Gross combination weight is the actual total weight of all units in a combination vehicle and everything they carry. It includes the power unit, the towed unit or units, and the cargo. Do not confuse GCW with gross combination weight rating, which is a maximum rated value determined under the applicable definition.
