Determine the kind of equipment needed to make the rental car accessible. If you are renting the car for yourself, you will likely already know this, but if you are making a reservation for someone else, you will need to ask exactly what kind of devices they will need integrated into their rental car.
Check rental car websites or call local stores for information on their accessible vehicle options. Companies will be able to list the types of modifications available, and will also indicate if they rent other accessibility devices such as mobility scooters or vans with wheelchair lifts or ramps.
Confirm the date, time and location of travel so that the rental agency has availability of the right car at the right place and time.
Call the car rental agency and explain that you need to reserve a car for someone with a disability (there may be a designated phone number for such requests). Explain to the customer service representative the driver's needs and list any equipment that is required, along with the confirmed time of travel.
