Review all 16 questions with answers

  1. During the low-speed service-brake check, the truck stops but pulls sharply left. What does that indicate?

    Correct answer: A possible brake problem that needs attention.

    The check assesses both stopping action and whether the vehicle pulls to either side. A pull or poor stopping performance can indicate a braking problem and should not be treated as a pass.

  2. Your test vehicle's air safety devices differ from those on the truck you first trained in. What should guide your demonstration?

    Correct answer: The test vehicle's manufacturer-specified procedures and equipment.

    Air safety devices vary. The cited inspection guidance requires knowing and explaining the specifications for the vehicle being tested; a generic script is not a substitute for understanding its actual system.

    Source: Colorado CDL Manual (06/15/23), Section 11M.1.2, Air Brake Check, physical PDF page 136. Modernized testing model; reviewed September 14, 2026. ↗

  3. What must you identify while demonstrating the air-gauge and governor cutoff check?

    Correct answer: The cutoff pressure reached by the actual test vehicle.

    Demonstrate that the air gauge works and pressure builds to governor cutoff, then identify that vehicle's cutoff pressure. The end of the gauge scale is not the governor setting.

  4. With the engine stopped, what electrical condition is needed for the low-air warning demonstration?

    Correct answer: Keep the key or electrical power in the on position.

    The warning check is performed without restarting the engine, with electrical power on so the warning devices can operate. Know the applicable system's specifications; this question does not prescribe one warning-pressure value for every vehicle.

  5. In the applied air-leakage test described in the cited inspection guidance, when do you begin the one-minute observation?

    Correct answer: After full foot-brake application and stabilization of the gauge.

    After setting up and securing the vehicle as required, fully apply the foot brake and let the gauge stabilize before measuring the one-minute loss. The initial application drop is not the timed leakage measurement.

  6. One hydraulic-brake test vehicle requires the engine running; another has different power-assist instructions. Which approach is appropriate?

    Correct answer: Demonstrate the manufacturer's procedure for the actual system.

    Hydraulic systems and power-assist checks vary. The cited inspection guidance calls for the vehicle-specific procedure, including the specified ignition or engine condition, rather than a universal engine-on or engine-off rule.

  7. A bus entrance closes securely, but a step tread is loose. Is the entrance inspection satisfactory?

    Correct answer: No; the steps and secure walking surfaces also need inspection.

    The entrance check includes the door, handrails, step lights when equipped, clear steps and secure tread. A working door does not make a loose walking surface acceptable.

  8. What travel condition should you demonstrate for an equipped passenger lift?

    Correct answer: Fully retracted and securely latched, with damage and leaks checked.

    The lift must be fully retracted and latched for travel. The inspection also addresses damage, missing parts, leaks and how correct operation is checked.

  9. In the school-bus inspection described by Tennessee’s linked handbook, how should you demonstrate knowledge of emergency exits?

    Correct answer: Operate at least one and explain the others, including warnings.

    The school-bus section calls for an operating demonstration and explanation of the other exits. Check release operation, secure closure and warning devices; coach/transit checks have their own scope.

  10. An equipped school's crossing safety arm is mounted firmly. What operating check is also required?

    Correct answer: It extends fully and works with the stop-arm system.

    Mounting condition is one part of the check. The safety arm must also function properly with the stop arm and extend fully, with no loose, broken or damaged parts.

    Source: Colorado CDL Manual (06/15/23), Section 11M.3, Stop Arm(s) and Safety Arm, physical PDF page 138. Modernized testing model; reviewed September 14, 2026. ↗

  11. Why inspect the seals on the school bus's first-aid and body-fluid cleanup kits?

    Correct answer: A broken seal can indicate that contents are missing.

    The handbook calls for both kits to be present and their seals intact. A broken seal can signal missing supplies and needs attention; merely seeing a kit container does not establish its readiness.

  12. Rust trails or shiny areas appear around wheel fasteners. What are you looking for?

    Correct answer: Possible loose fasteners, missing nuts or damaged stud holes.

    The wheel inspection looks for signs of loose or damaged fastening, including rust trails and shiny surfaces. Explain the warning signs instead of treating the presence of nuts as proof of security.

    Source: Colorado CDL Manual (06/15/23), Section 11M.5.2, Lug Nuts, physical PDF page 139. Modernized testing model; reviewed September 14, 2026. ↗

  13. For a tire without an applicable automatic checking system, what demonstrates an actual inflation check?

    Correct answer: Use a tire-pressure gauge rather than judging by a kick.

    A tire gauge measures air pressure; kicking or looking at the tire does not. If special monitoring equipment is fitted, understand its actual function rather than assuming every monitoring system also adjusts pressure.

  14. The steering linkage is not visibly bent. What else belongs in its inspection?

    Correct answer: Secure connections and required nuts, bolts and cotter pins.

    Check the linkage for wear and damage as well as secure mounting and retained connections. An unbent part can still be unsafe if a connection is loose or a required retaining pin is missing.

  15. Why inspect spring hangers and mounting hardware as well as the springs?

    Correct answer: A sound spring still needs secure, undamaged attachment points.

    Suspension inspection includes the springs and their mounting components. Missing or damaged attachments can be a defect even when the visible spring itself is intact.

    Source: Colorado CDL Manual (06/15/23), Section 11M.5.2, Suspension, physical PDF page 140. Modernized testing model; reviewed September 14, 2026. ↗

  16. A brake hose is present but rubbed deeply at a nearby bracket. What should the inspection address?

    Correct answer: Its damage, connections and possible leakage.

    Brake hoses and lines must be checked for damage and leaks, with secure fittings. Simply finding a hose in place does not establish that its condition is safe.

Tennessee CDL inspection and skills study: test 2

Brakes, passenger equipment and wheel checks. 16 questions with immediate explanations. This is an untimed learning test.

All topics and study tools

Basic-control questions follow the older 2005 model in Tennessee’s linked handbook, not modernized Section 12M. Confirm your examiner’s current format and allowances. Shared inspection and road questions retain their real sources; a written quiz cannot certify practical skills.Read Tennessee’s basic-control section

Twenty-one items use Tennessee’s linked handbook or current licensing page, including the complete basic-control study set. Fifty-nine shared physical-inspection and road scenarios retain their actual Colorado DMV-linked source. Tennessee’s PDF describes the older 2005 testing model; current examiner arrangements remain unconfirmed. Its look and boundary rules are not modernized-test allowances. Equipment checks must follow applicable rules and manufacturer procedures. This is study, not hands-on certification.
