  1. Which type of hand control is most appropriate for a driver who needs simultaneous acceleration and braking capability with one hand?

    Answer: Electronic hand control with proportional input

    Electronic proportional hand controls allow precise modulation of both acceleration and braking simultaneously through a single input device, ideal for drivers with limited upper extremity function.

  2. A driver with C6 complete spinal cord injury is being evaluated. Which steering device is typically most appropriate?

    Answer: Tri-pin steering device

    A tri-pin device provides secure wrist/hand placement for individuals with C6 SCI who have wrist extension but limited hand grip.

  3. When assessing a client for left-foot accelerator use, the primary safety concern the CMC must address is:

    Answer: Ensuring the original right accelerator is disabled or removed

    The original right-side accelerator must be disabled or removed to prevent inadvertent activation when a left-foot accelerator is installed.

  4. Which RESNA standard primarily governs the securement of wheelchairs used as seats in motor vehicles?

    Answer: ANSI/RESNA WC-19

    ANSI/RESNA WC-19 (also aligned with ISO 7176-19) sets crashworthiness requirements for wheelchairs used as vehicle seats.

  5. A client reports that their powered steering system feels 'vague' after a recent vehicle modification. The most likely cause is:

    Answer: Incorrect tie-rod adjustment post-lift installation

    Lift installations that alter vehicle suspension geometry can affect tie-rod alignment, resulting in vague or imprecise steering feel.

  6. Under NMEDA quality assurance guidelines, an adaptive equipment dealer must retain installation documentation for a minimum of:

    Answer: 7 years

    NMEDA QAP standards require that installation records be retained for a minimum of 7 years to support warranty claims, recalls, and liability documentation.

  7. A client with hemiplegia wants to drive using a spinner knob on the right side of the steering wheel. The CMC should first verify:

    Answer: Whether the client's dominant hand is the affected or unaffected limb

    Determining which side is affected versus unaffected dictates spinner placement and which compensatory strategies will be most effective.
