The target group consists of people with special needs (PSN), defined as people with a medical
condition that has or may have an effect on their fitness to drive. These medical conditions include
problems of a purely physiological, motor, psychological or pure medical nature. Several reasons
might trigger the beginning of the process. The most common reason is the referral by an MD (mostly
after the change in medical condition), but also insurance companies can refer people. In some cases,
these people have themselves checked because at the same time they can also get advice on the
possible adaptations to the car (e.g. to compensate motor problems).
