NDIS Vehicle Modifications

Occupational therapy assessment, prescription and reporting for vehicle modifications — so you can drive, or travel safely as a passenger, in a vehicle set up for you.

Vehicle modifications are funded under the NDIS as Capital Supports — Assistive Technology, and they are among the most complex and highest-cost items the scheme funds. They also take longer than almost anything else, which is why the order you do things in matters enormously.

Get the Assessment Before You Buy the Car

This is the single most useful thing on this page.

Modifications have to be engineered into a specific vehicle. Not every vehicle can take every modification — floor height, door aperture, wheelbase, roof height, suspension, boot dimensions, seat rails and where the airbags sit all determine what is possible and what it costs.

People regularly buy a car first, then discover the modification they need cannot be fitted to it, or can only be fitted at two or three times the cost of doing it in a different vehicle. The NDIS will not usually fund replacing a vehicle that was the wrong choice.

So the sequence is: occupational therapy assessment first, vehicle recommendation second, purchase third, modification fourth. If you are already committed to a vehicle, tell us at the start and we will assess what is realistic within it rather than recommending something that cannot be delivered.

What the NDIS Does and Does Not Fund

Funded: the modifications themselves, where they are reasonable and necessary, relate to your disability, and represent value for money.

Not funded: the vehicle itself. The NDIS funds modifications to a vehicle, not the purchase of one. It also will not fund modifications where a lower-cost option would meet the need, where the need is not disability-related, or for standard running costs, registration, insurance and servicing.

Evidence matters here more than almost anywhere else in the scheme. High-cost modifications require a detailed occupational therapy assessment and report addressing your functional need, the options considered, why the recommended option is the appropriate one, and value for money. Vague reports get returned, and each return adds months.

Driver Modifications and Passenger Modifications

These are two different pathways with different requirements, and the distinction decides who assesses you.

Driver modifications — where the person with disability drives the vehicle. Hand controls, left foot accelerators, steering aids and spinner knobs, pedal extensions and blocks, secondary control systems, seat and transfer modifications for the driver's position.

Driver modifications require an occupational therapy driver assessment, carried out by an occupational therapist with specific driver assessor training, usually including an off-road assessment and an on-road assessment with a driving instructor. Your licensing authority applies conditions to your licence based on that assessment. We do not currently have occupational therapists with driver assessor qualifications on our team. We refer driver assessments on to a qualified driver-trained assessor, and we complete joint assessments with vehicle modifiers to ensure the best solution is recommended.

Passenger and transport modifications — where the person travels as a passenger. Wheelchair accessible vehicle conversion, ramps and lifts, lowered floors, wheelchair docking and restraint systems, occupant restraints, swivel and transfer seats, person hoists, and wheelchair or scooter hoists to load equipment into a boot.

Our occupational therapists complete passenger and transport assessments, working with vehicle modifiers and, where the person also intends to drive, alongside a driver-trained assessor.

What We Assess and Prescribe

Getting In and Out

Transfers between wheelchair and vehicle seat, swivel and slide seats, transfer boards, grab handles, step and running board changes, and person hoists where a manual transfer is unsafe for the person or whoever assists them.

Travelling Safely as a Passenger

Wheelchair docking and tie-down systems, occupant restraints (a Behaviour Support Practitioner is required to include any physical restraints to the Behaviour Support Plan), postural support, and head and trunk support. Restraint systems for wheelchair passengers must comply with the relevant Australian Standards — a wheelchair that is not properly restrained is a serious crash risk to everyone in the vehicle, and this is not an area for improvisation.

Loading Equipment

Boot hoists and cranes for wheelchairs and scooters, internal loading systems, and rooftop stowage. Often the difference between someone being able to go out independently and not.

Wheelchair Accessible Vehicle Conversion

Lowered floor conversions, rear and side entry ramps, powered lifts, and internal layout — including where the person will sit, sightlines, and whether they can travel beside family rather than facing the back doors.

Children and Young People

Postural support car seats, special purpose restraints, harnesses and modified seating for children whose needs are not met by a standard child restraint.

Reassessment as Things Change

Growth, a change in wheelchair, a progressive condition, or a new vehicle all mean the setup needs revisiting.

When to Seek an Assessment

  • You are planning to buy a vehicle and will need it modified
  • Transfers into or out of the car have become difficult or unsafe
  • Someone is lifting a wheelchair or the person, and it is not sustainable
  • You have a new wheelchair that does not fit the current setup, or is not properly restrained
  • You want to return to driving after a stroke, brain injury, spinal cord injury or amputation, or with a progressive condition
  • A child has outgrown standard restraints or needs postural support
  • An NDIS plan review is coming up and vehicle access needs evidence

Speak to your doctor and your licensing authority if:

  • You have a medical condition that may affect your ability to drive safely. In Australia you have a legal obligation to notify your state or territory driver licensing authority of any long-term condition affecting driving. Your GP or specialist can advise, and driving must not resume until you are medically cleared
  • You have had a stroke, seizure, brain injury or significant vision change — there are mandatory non-driving periods, and they vary by condition
  • Your function has changed since your licence conditions were set

Arrange urgent review if a wheelchair is not securely restrained during travel, or if a hoist, ramp or docking system is not working as intended. Stop using it until it has been checked.

We assess function and prescribe modifications. We do not determine medical fitness to drive — that is a matter for your doctor and the licensing authority.

What to Expect

Assessment usually takes place at home, and takes around 90 minutes to two hours.

Your occupational therapist will discuss what you need the vehicle to do — who drives, who travels, how often, what equipment comes along, and who assists. They will assess your physical function, transfers, strength, range and posture, and look at your wheelchair or mobility equipment in detail, including its dimensions and weight.

They will assess your current vehicle if you have one, or discuss vehicle options if you do not, and will usually arrange a joint assessment with a vehicle modifier so what is prescribed is something that can actually be engineered.

You will receive a written assessment and prescription addressing the NDIS evidence requirements, with quotes obtained through modifiers, alternatives considered, and clear clinical reasoning. We work with your support coordinator or plan manager through submission and respond to requests for further information.

After installation we attend the fitting where practical, check the modification does what it was prescribed to do, and provide training for you and anyone assisting.

On timeframes, honestly: this is a long process. Assessment, joint assessment with a modifier, quoting, NDIS decision, build and installation commonly add up to many months. Start earlier than you think you need to, and do not order a vehicle around an assumed approval date.

Where We Provide This Service

Occupational therapists across Victoria (Melbourne, Roxburgh Park and the northern suburbs), Queensland (Brisbane, Gold Coast, Sunshine Coast, Ipswich and Logan) and New South Wales (Sydney and Western Sydney).

Assessments are delivered at home, and jointly with vehicle modifiers at their premises where the vehicle needs to be present.

Funding We Accept

  • NDIS — the main pathway. Vehicle modifications sit under Capital Supports — Assistive Technology, with the occupational therapy assessment under Capacity Building. High-cost modifications carry additional evidence requirements, and our reports are written to address them. Agency-managed, plan-managed and self-managed participants are all welcome.
  • TAC — for Victorians injured in a transport accident, where vehicle modification relates to an accepted claim.
  • Workers compensation — where related to an accepted claim.
  • DVA — for eligible veterans with a valid referral.
  • Private — no referral required.

Vehicle modifications are generally not funded through Support at Home or the AT-HM scheme, which cover assistive technology and home modifications rather than vehicles. Aged care can fund some vehicle modifications.

Simple Process

Getting Started

1

Make a referral

Participants and families, support coordinators and plan managers, GPs and rehabilitation specialists, hospital and rehabilitation teams and vehicle modifiers can all refer.

2

We call you for an initial discussion

Our team asks whether you intend to drive or travel as a passenger, what vehicle you have or are considering, what mobility equipment travels with you, who assists with transfers, what NDIS funding is in place, and whether a driver assessment is likely to be needed. Where it is, we explain that pathway before anything else begins.

3

Functional and vehicle assessment

Assessment of function, transfers, equipment and the vehicle, at home and with the vehicle present where required.

4

Joint assessment with a modifier

A joint session with a vehicle modification specialist, so the prescription is engineerable rather than theoretical.

5

Report, quotes and submission

A written prescription and report meeting NDIS evidence requirements, with quotes, submitted with your support coordinator.

Got Questions?

Frequently Asked Questions

Will the NDIS buy me a car?
No. The NDIS funds modifications to a vehicle, not the vehicle itself, along with the assessment that supports them.
Should I buy the vehicle first?
No — get the assessment first. Not all modifications suit all vehicles, and buying first is the most common and most expensive mistake in this area.
How long does it take?
Commonly many months, once assessment, joint assessment, quoting, NDIS approval, build and installation are counted. Start early.
Do I need a driving assessment?
If you intend to drive, yes. Driver modifications require an occupational therapy driver assessment by a driver-trained assessor, and your licensing authority sets licence conditions from it.
Can I be assessed if I don't currently hold a licence?
Usually you will need at least a learner permit and medical clearance before a driver assessment. Our intake team can explain the sequence for your state.
Who pays for the driving lessons?
Arrangements vary and are decided by the NDIA in your plan. We will tell you what is typically funded and what is not, so it is not a surprise.
My wheelchair changed — do we need to reassess?
Usually yes. Docking systems, restraints and clearances are specific to the chair, and a new chair frequently will not fit an existing setup safely.
Can you help with a vehicle for a child?
Yes, including postural support seating and special purpose restraints where a standard child restraint does not meet the need.
