CD - "If you drive and you are diagnosed with M�ni�re�s disease, or you are experiencing the primary symptoms of vertigo and hearing loss, then you must inform the Driver and Vehicle Licensing Agency (DVLA) of your condition. The DVLA states that if you drive a car, or motorcycle, and you have recently been diagnosed with M�ni�re�s disease, you must cease driving. Driving will not be permitted again until you have satisfactory control of your symptoms. Your GP or ear, nose and throat specialist will have to confirm that your symptoms have improved and are under control...
The DVLA will send you a questionnaire to find out how your condition affects you. They will also ask permission to contact your GP, or ENT specialist, so that they can make a more detailed assessment of your physical ability to drive."
