The reviewed 319-page manual identifies itself as DL-151 (02/26), February 2026. Internal question citations and the chapter links below use a public mirror of that Maryland-authored document. The mirror is hosted by a third party, not the MVA. The official link is provided separately so you can check for updates.

Open PDF page 280 on the public mirrorHow we built this practice
Our 744 original scenarios were checked September 15, 2026. Questions on tire requirements, warning devices, texting, required railroad stops, cargo inspections and detailed securement rules, brake equipment, low-air warnings, bus inspection reports, passenger protection, permitted hazardous cargo, tank classification and safety connections cite the applicable federal sources directly. Other questions cite individual manual sections and pages. School-bus operating questions also cite Maryland statutes and COMAR. Generic safety guidance is not presented as a separate Maryland statute. We do not reproduce the manual’s artwork or official exam questions.
Page 9 specifies an 80% passing score for each required knowledge test. Our general practice uses 50 questions with a 40-correct target; separate air-brake practice uses 25/20 and combination, passenger, tank, doubles/triples and school-bus practice use 20/16. Hazardous-material practice uses 30/24. These lengths are learning choices, not claims about the MVA exam’s length. Four choices, immediate explanations and untimed attempts are our study format. The 96 licensing questions cover classes, learner permits, training, medical status, driver responsibilities and Maryland procedures. The 80 written inspection and skills questions address Sections 11–13 in five 16-question sets. They do not replace hands-on training or practical tests. The 64 operating and recordkeeping questions add medication and alcohol restrictions, restraints, Maryland rail-stop rules, CDL exclusions, the military skills-test waiver, and IRP/IFTA qualifications and records. This question set still does not cover every part of the manual. Read the complete requirements for your vehicle and training path.
For cargo, distinguish a simplified handbook summary from the detailed federal rule: tiedown count depends on length, weight and forward blocking, while working load limit is a separate requirement. Our count scenarios state which rule applies and explain its conditions. Special-commodity rules can add requirements; these general questions do not replace them.
Air-brake questions distinguish older-vehicle warning rules from FMVSS 121 requirements. The low-air warning, governor settings, spring-brake application and tractor protection valve have different purposes and thresholds. Follow the applicable rule and the equipment’s instructions; do not treat a handbook example as a universal specification.
Some passenger-section summaries in the handbook use older inspection-report and hazardous-material wording. These questions cite the current federal provisions directly, including their exceptions; a personal cheat sheet or this quiz does not authorize carrying a prohibited material.
Maryland does not permit triple-trailer highway operation. T-endorsement practice covers subject knowledge; it is not permission to operate triples in Maryland. Read §24-104.1(l)
State-law questions identify the Maryland requirement. COMAR questions concern covered local-school-system transportation; local procedures may be stricter. Handbook recommendations are not presented as separate state laws. For example, the statutory amber-light minimum at a standard on-roadway student stop is 100 feet, while the handbook gives a generic 200-foot example. On-roadway loading and approved loading zones outside the roadway have different signal rules. Maryland student transportation rules
Hazardous-material rules include shipment-specific exceptions. These study questions do not replace required ELDT, employer hazmat training, a security assessment or the current regulations. Training deadlines, shipping-paper retention, placarding exceptions, cargo-tank attendance and incident-reporting questions use the current federal rules. The manual’s older ORM-D entries and its “more than one hour” public-evacuation reporting wording are not used as current law.
Licensing questions use current MVA pages and federal rules, not another state’s procedure. Covered first H applicants complete ELDT before the H knowledge test; P and S follow the applicable skills-test sequence. Maryland’s medical certification and waiver rules still apply to its excepted categories. Electronic medical reporting does not remove required waiver carrying. Six 16-question licensing sets are study groups, not separate official examinations.
These four study sets are not a separate MVA exam. Follow the applicable state and federal operating rules. IRP concerns vehicle registration; IFTA concerns fuel-tax reporting. The recordkeeping questions cover a Maryland IFTA licensee, not every vehicle or business. A CDL exclusion or military skills-test waiver does not waive every licensing, medical or operating requirement. Use current agency guidance where a handbook summary is incomplete: the IRP three-axle criterion is independent of weight; Maryland IFTA records are handled by the Comptroller. A placard is not the sole trigger for Maryland’s special railroad-stop law.
