Accessible vehicle leases and equipment
People who get the highest rate of the mobility component of CDP will be able to transfer either the whole or part of the money they get for the mobility component to access the Accessible Vehicles and Equipment Scheme. This new Scottish scheme will provide a service similar to the current Motability scheme, with a range of cars, wheelchair accessible vehicles, scooters and powered wheelchairs on affordable leasing terms, with a range of adaptations at little or no cost. Clients who have an existing Motability lease will be able to retain their vehicle until the end of that lease.
