DLM1 forms are available from MOT test centres. You can also contact Driver & Vehicle Agency (DVA) to request one:

Medical practitioners

More detailed information on the above conditions and driving can be located in the 'at a glance guide for medical practitioners'.

Surrender your driving licence then re-apply

The medical standards of fitness to drive are available to all medical practitioners. If your doctor, in line with these standards, has advised you that you shouldn't drive, you may wish to surrender your licence. You can re-apply for it at a later date.

Surrendering your licence has an advantage, if and when you decide to re-apply.
