32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Class A combination vehicle
A combination vehicle with a gross combination weight rating of 26,001 pounds or more, where the towed unit or units have a gross vehicle weight rating exceeding 10,000 pounds.
Class B single vehicle
A single vehicle with a gross vehicle weight rating of 26,001 pounds or more, or such a vehicle towing a unit that does not exceed 10,000 pounds gross vehicle weight rating.
Class C vehicle
A single vehicle with a gross vehicle weight rating of 26,000 pounds or less that is designed to carry 16 or more passengers including the driver, or is placarded for hazardous materials.
Passenger endorsement P
Required to operate any vehicle designed to carry 16 or more passengers including the driver. For a school bus it is combined with the school bus endorsement.
School bus endorsement S
An endorsement added to a passenger endorsement that permits operation of a school bus. It requires a knowledge test and a skills test performed in a school bus.
School bus driver certificate
A California credential separate from the CDL, requiring fingerprint background clearance, medical certification, and a driving record review, issued through the CHP and DMV process.
Commercial learner's permit limits
A permit holder may not carry passengers in a school bus and must be accompanied by a licensed driver. A minimum holding period applies before the skills test.
CDL disqualifying offenses
Serious traffic violations and certain criminal offenses can suspend or revoke CDL privileges even when committed in a personal vehicle, and school bus drivers face stricter standards.
Self-certification category NI
Non-excepted interstate. The driver operates across state lines or in non-excepted operations and must keep a current DOT medical examiner's certificate on file with the state.
Self-certification category NA
Non-excepted intrastate. The driver operates only within California in non-excepted operations and must meet the state medical certification requirements for that category.
Excepted operation definition
Operation limited to excepted categories such as federal government, certain school bus operations, or emergency response. Excepted drivers are not required to file a medical certificate with the DMV.
Medical certificate validity period
Generally 24 months maximum, but shortened to 12 months or less when the examiner identifies a condition requiring monitoring, such as elevated blood pressure or certain cardiac conditions.
DOT vision standard
At least 20/40 corrected vision in each eye, a visual field of at least 70 degrees in each eye, and the ability to distinguish red, green, and amber colors.
DOT hearing standard
The driver must be able to perceive a forced whisper at a distance of 5 feet, with or without a hearing aid, in order to meet the federal medical standard.
Hypertension certification limits
Stage 1 and stage 2 hypertension generally limit certification to 3 months, stage 3 to 6 months, and readings of 180/110 or higher disqualify until the condition is controlled.
Insulin-dependent diabetes certification
A driver may be certified under the federal diabetes exemption program with an endocrinologist's assessment. A disqualifying hypoglycemic episode must be reported and may bar driving.
DL-51 medical certificate
The California medical examiner's certificate form that school bus drivers must carry and keep current, in addition to meeting the federal DOT medical standard.
Clearinghouse pre-employment query
A full query an employer must run, with the driver's electronic consent, before allowing a CDL driver to perform safety-sensitive functions such as driving a school bus.
Clearinghouse annual limited query
A query employers must run at least once a year on every employed CDL driver. A limited query shows whether a record exists but not its details.
Clearinghouse prohibited status
A driver with a reported violation, including a positive drug test, alcohol result of 0.04 or higher, refusal to test, or actual knowledge, may not perform safety-sensitive functions.
Substance abuse professional role
The SAP evaluates a driver after a violation, prescribes education or treatment, and directs the return-to-duty and follow-up testing process required before driving privileges resume.
Return-to-duty process
After a violation, the driver must complete SAP evaluation and treatment, pass a negative return-to-duty test, and then complete follow-up testing before resuming safety-sensitive duties.
Follow-up testing minimum
Follow-up testing lasts at least 12 months and includes at least 6 tests in the first 12 months, as directed by the substance abuse professional, until the driver is released.
Clearinghouse record follows driver
A violation record stays with the driver across employers. A new employer's full query reveals prohibited status, so changing jobs does not clear the record.
Employer reporting duties
Employers must report violations, refusals to test, and negative return-to-duty and follow-up test results to the Clearinghouse. Failure to report can result in civil penalties.
Entry-Level Driver Training applicability
ELDT applies to first-time Class A or Class B applicants, Class B to Class A upgrades, and first-time passenger or school bus endorsement applicants.
Training Provider Registry
The FMCSA list of approved ELDT providers. Providers must be listed and must submit the driver's completion certification electronically; drivers cannot self-certify completion.
ELDT theory instruction
Classroom or online instruction covering basic operation, safe operating procedures, vehicle systems, and non-driving activities, completed before the CDL skills test.
Behind-the-wheel training
Required for Class A and Class B applicants but not for the passenger or school bus endorsement alone, which requires theory instruction plus the state skills test.
CDL skills test parts
Three parts: pre-trip vehicle inspection, basic vehicle control, and on-road driving. Failure of any part requires retesting that part, and the school bus test uses a school bus.
School bus pre-trip training
Instruction in inspecting the bus before each trip, including brakes, lights, tires, emergency exits, mirrors, and passenger safety equipment, as part of the school bus endorsement curriculum.
Student management training
Instruction in loading and unloading procedures, student behavior management, emergency evacuation drills, and railroad crossing procedures required for school bus drivers.
