Indiana CDL manuals and sources

How we built this practice

16 Indiana licensing questions, 64 vehicle-control and inspection questions, 64 conditions and emergency questions, 48 cargo questions, 48 air-brake questions, 48 combination-vehicle questions, 40 passenger questions, 24 tank questions, 24 doubles/triples questions, 64 school-bus questions, 80 hazardous-materials questions and 80 inspection/skills-preparation questions. Thirty-eight non-overlapping short tests reuse these same records. The core marathon and random draw use only the first 192; specialist pages have their own separate question sets and random draws. Study modes do not add more questions to the count.

Local licensing questions use current Indiana BMV requirements and the July 2026 Indiana-specific supplement. Shared safety and cargo scenarios retain their actual Colorado DMV-linked handbook or federal sources, compared with Sections 2–3 of the Indiana manual. Federal questions preserve the stated scope and exceptions; a handbook summary is not a substitute for the cited regulation.

School-bus local rules use Indiana sources. On U.S. or state routes outside city or town boundaries, a stop requiring a student to cross is not permitted when another safe alternative is available. Railroad scenarios state when the stopping requirement applies, including the 15–50-foot range, looking and listening, and no shifting on the tracks. Indiana also requires a seat-by-seat check after each passenger trip and before exiting, not just at the end of the day. General handbook procedures remain subject to Indiana law and district instructions.

The main manual is the BMV-linked September 2022 modernized-testing edition; its safety chapters retain July 2017 footers. The separate Indiana supplement is marked SP283 R-5 7/26. September 14 is our review date, not a new manual edition.

Cargo: read the stated rule and exceptions

The manual gives a simplified two-tiedown minimum. Questions expressly asking about 49 CFR 393.110 use its actual length, weight and forward-blocking rules, including the short-and-light one-tiedown case. Meeting the count alone does not establish adequate strength or securement.

Similarly, the sealed-load and impracticable-inspection exceptions in 49 CFR 392.9 do not remove general cargo-safety or weight duties. Our federal scenarios keep those qualifications instead of turning a summary into a universal rule.

Still to study separately

The skills-preparation question set is written study, not hands-on training or an examiner assessment. Specialist practice covers selected scenarios, not every hitch, inspection procedure or exception. Choose the additional official manual sections and training that apply to your intended vehicle and work. Use these questions alongside the full handbook.

Independent knowledge practice, not a BMV examination, registered entry-level driver training (ELDT), medical certification or permission to operate a commercial vehicle. Complete the applicable BMV and training requirements separately. Short tests and random draws are our study formats, not verified official exam lengths or topic weighting.

Air brakes: which warning threshold?

The Indiana manual discusses a 55 psi warning. Our questions expressly distinguish equipment subject to FMVSS 121, S5.1.4–S5.1.5: with the ignition on, the low-air signal must warn continuously below 60 psi, separately from the service-system pressure gauge. It may be visible, or both visible and audible; a buzzer alone is not that standard's requirement.

For older non-FMVSS-121 equipment, 49 CFR 393.51(c)(2) instead specifies 55 psi or half compressor cut-out pressure, whichever is less, with separate exceptions. Do not treat these as one universal number or confuse them with spring-brake application pressure. Follow the applicable requirements and manufacturer.

Combination questions preserve the scope of 49 CFR 393.43: tractor protection acts automatically within 20–45 psi; the breakaway-duration scenario is expressly an ordinary two-axle trailer, not a driveaway-towaway operation. Federal wording and actual equipment determine the applicable requirement.

Our equipment scenarios retain their actual Colorado handbook or federal citations, compared with Indiana Sections 5–6. We do not present another state's licensing rules as Indiana rules or reproduce the manual's sample practice questions.

Passenger and tank practice: precise rules

The older manual describes a written no-defect report for an interstate bus. Current 49 CFR 396.11(a)(2)(i) does not itself require one when no defect is discovered or reported. That does not remove safety inspections, required defect reports or additional employer and applicable local requirements. Our questions explicitly distinguish those duties.

Passenger hazardous-material scenarios use 49 CFR 177.870, including the precise 45 kg (99 lb) per-class and 225 kg (496 lb) aggregate limits for authorized non-Class 1 articles when no special exception applies. Weight alone does not authorize carriage: material, packaging, stowage and other restrictions still apply. The manual's rounded 100/500 lb values and ORM-D wording are not used as current shipment permission.

Tank questions retain the exact 49 CFR 383.5 definition: individual rated capacity greater than 119 gallons and aggregate rated capacity at least 1,000 gallons. The empty, non-transport storage-container exception is narrow. These are classification scenarios for CDL-required vehicles, not permission to bypass other licensing, cargo or hazardous-material requirements.

Passenger and tank question sets were compared with Indiana Sections 4 and 8. Actual Colorado handbook and federal citations remain attached to our original questions. These sections do not replace passenger skills testing, applicable training or product-specific tank operating procedures.

Hazardous materials: use the applicable rule

Our 80-practice questions was compared with Indiana Section 9. Questions retain their actual Colorado handbook, FMCSA or federal citations. Old ORM-D wording, simplified placard thresholds and the handbook's older incident-reporting summary are not used as current shipment authorization. Read each question's conditions: bulk versus non-bulk packaging, hazard class, gross weight, attendance method and specific exceptions matter.

For an incident requiring NRC notification, PHMSA's incident-reporting guidance distinguishes notice as soon as practical, no later than 12 hours after occurrence, from the detailed report due within 30 days of discovery. These deadlines do not permit delaying emergency assistance or unsafe scene investigation. Not every release has the same reporting obligations or exceptions.

The five short tests and random 20-question mode are our study formats, not a verified Indiana H exam length. Review the BMV's endorsement requirements and complete applicable ELDT, the threat assessment and employer-specific training separately. A correct quiz response does not authorize handling a substance or responding to a release.
