If you are diagnosed with a long term or permanent medical condition that affects your driving, you are required to notify the department.
If your doctor has assessed you as medically fit to drive you can present your medical certificate to the department so this can be reflected on your licence, but
this is not mandatory.
In some cases, if your doctor considers that continuing to drive may be unsafe, you will be issued with a medical certificate indicating that you do not meet the medical criteria to hold a licence and that you should no longer drive.
When renewing your licence, you are still eligible to select from the range of terms available to everyone (up to 5 years).
