Massachusetts CDL Practice Test

Correct answer: 18 years old

Massachusetts issues a CLP at age 18 for intrastate (in-state) transport. You must be at least 21 for an interstate CLP that lets you drive a CMV across state lines.

Correct answer: A “K” restriction — Intrastate Operation Only (Massachusetts only)

Federal rules require a driver to be 21 to operate a CMV in interstate commerce, so Massachusetts issues under-21 CDL holders a “K” restriction limiting them to intrastate (within-Massachusetts) driving.

Correct answer: A Class D (passenger) driver’s license valid for the entire length of the commercial permit

To apply for a CLP you must have a Class D license that will stay valid for the whole life of the commercial permit, be a Massachusetts resident with lawful presence and a valid Social Security number, and not hold a license in any other state.

Correct answer: $30

The Learner’s Permit Application Fee is $30. Adding a CDL endorsement during the same transaction costs $10 each; an endorsement added on a different day costs $30 each.

Correct answer: 180 days, renewable one time for an additional 180 days at no fee

A Massachusetts CLP expires 180 days from the date of issue and can be renewed one time for another 180 days for no fee. You must renew within 30 days of expiration — otherwise you have to take and pass the written tests again at your own expense.

Correct answer: English, Spanish, and Portuguese

The commercial general knowledge and all endorsement tests are offered in English, Spanish, and Portuguese, selected at the testing station computer. The road (skills) test must be given in English, and no foreign-language interpreter is ever allowed on a knowledge test.

Correct answer: 40

You need 40 of 50 correct — the federal 80% passing standard. The air brakes exam is 20 of 25 and the combination vehicles exam is 16 of 20, both also 80%.

Correct answer: 26,001 lbs or more

A CDL is required for any single vehicle rated 26,001 lbs GVWR or more, a combination rated 26,001 lbs GCWR or more when the towed unit(s) exceed 10,000 lbs, a vehicle designed for 16 or more passengers, or any vehicle requiring hazardous-material placards.

Correct answer: 16 or more, including the driver

Any vehicle designed to carry 16 or more people, including the driver, requires a CDL — which is why passenger and school-bus operators need commercial licensing regardless of the vehicle’s weight.

Correct answer: The combination vehicle endorsement written exam

A Class A CDL requires the combination vehicle endorsement, so you pass the general knowledge written exam, the combination written exam, and the road exam. Other endorsements (H, N, P, T, S) are optional add-ons.

Correct answer: 0.04% or more

The CMV limit is 0.04% — half the 0.08% limit for non-commercial drivers. By operating a CMV you are deemed to have consented to alcohol testing.

Correct answer: 1 year

A first major offense disqualifies you from driving a CMV for at least one year. Major offenses include a 0.04+ BAC, driving under the influence, refusing alcohol testing, and leaving the scene of a CMV crash.

Correct answer: 3 years

The one-year disqualification for a first major offense is extended to at least three years if the offense occurs while operating a CMV placarded for hazardous materials.

Correct answer: Loss of your CDL for life

A second major offense disqualifies you from holding a CDL for life. (A lifetime disqualification may be reduced under limited conditions set by the state.)

Correct answer: To submit to alcohol testing

If you operate a CMV, you are deemed to have given consent to alcohol testing. Refusing the test is itself a major offense carrying a one-year disqualification.

Correct answer: You lose your CDL for at least 60 days

Two serious traffic violations in a CMV within a three-year period disqualify you for at least 60 days. A third within three years raises it to at least 120 days.

Correct answer: Excessive speeding — 15 mph or more over the posted limit

Serious traffic violations include excessive speeding (15+ mph over the limit), reckless driving, improper or erratic lane changes, and following too closely. Parking violations do not count.

Correct answer: Medically certified as physically qualified

Drivers must be medically certified as physically qualified under the federal standards and, when required, carry the medical examiner’s certificate.

Correct answer: You receive a restriction barring you from driving a CMV equipped with air brakes

If you fail the air brakes knowledge test or take the skills test in a vehicle without air brakes, your CDL carries a restriction (the "L" code) prohibiting you from operating a CMV with air brakes.

Correct answer: You cannot be issued a Group A (Class A) CDL

Failing the combination vehicles portion means you cannot receive a Group A (Class A) CDL — which is why combination knowledge is the gate to driving tractor-trailers.
