Sample Massachusetts CDL Test Questions - General Knowledge

Question 1

Which shipment does not require a hazardous-materials endorsement solely because of its cargo?

  1. A A shipment that requires no placards and contains no select agent or toxin listed in 42 CFR part 73
  2. B Any shipment transported entirely within one state
  3. C A placarded shipment in a vehicle weighing less than 26,001 pounds
  4. D A placarded shipment when an endorsed passenger accompanies the driver

Correct answer: A – A shipment that requires no placards and contains no select agent or toxin listed in 42 CFR part 73

Federal CDL rules require an H endorsement for designated hazardous material that must be placarded and for any quantity of a select agent or toxin listed in 42 CFR part 73. Vehicle weight and intrastate travel do not eliminate that requirement. Another person’s endorsement does not authorize an unendorsed driver to operate the vehicle.

Question 2

A regulatory sign displays a U-shaped turning arrow crossed by a red circle and slash. What does the sign mean?

This sign indicates that ______________.
  1. A All turns are prohibited
  2. B U-turns are prohibited
  3. C The road is closed to through traffic
  4. D Traffic moves in one direction only

Correct answer: B – U-turns are prohibited

In Massachusetts, this regulatory sign prohibits drivers from making a U-turn at the posted location. It does not prohibit every type of turn or indicate that the road is one-way. A commercial driver must recognize and obey regulatory signs while operating on public roads.

Question 3

How far ahead should a commercial driver generally scan while driving?

  1. A 2 to 5 seconds
  2. B 5 to 10 seconds
  3. C 12 to 15 seconds
  4. D 15 to 25 seconds

Correct answer: C – 12 to 15 seconds

Drivers should generally look at least 12 to 15 seconds ahead, covering the distance the vehicle will travel during that time. This is approximately one block at lower speeds and one-quarter mile at highway speeds. Continue shifting attention between nearby conditions and the roadway farther ahead.

Question 4

Which item is checked as part of the suspension system rather than the steering system?

  1. A Missing fasteners on the steering box
  2. B A leaking shock absorber
  3. C Power-steering hoses, pump, and fluid level
  4. D A power-steering fluid leak

Correct answer: B – A leaking shock absorber

A leaking shock absorber is a suspension-system defect, not a steering-system item. Steering checks include the steering box and its mounting hardware, power-steering hoses and pump, fluid level, and leaks. Shocks are inspected with other suspension components such as springs and air bags.

Question 5

The radiator cap may be removed regardless of the engine’s temperature.

  1. A TRUE
  2. B FALSE

Correct answer: B – FALSE

Never remove the radiator or coolant cap while the engine is hot. The cooling system may be under pressure, and opening it can release hot coolant or steam and cause serious burns. Wait until the engine and cooling system have cooled before removing the cap.

Question 6

When carrying Division 1.1, 1.2, or 1.3 explosives, which locations are subject to a 300-foot no-parking rule?

  1. A A bridge or tunnel
  2. B A dwelling or place where people work, congregate, or assemble
  3. C An open fire
  4. D All of the above

Correct answer: D – All of the above

Federal rules generally prohibit parking a vehicle containing Division 1.1, 1.2, or 1.3 explosives within 300 feet of a bridge, tunnel, dwelling, or place where people work, congregate, or assemble. A limited operational-necessity exception applies to that rule. A separate federal rule prohibits any hazardous-material vehicle from parking within 300 feet of an open fire.
