Medical Issues

The medical conditions that will preclude you from driving a motorised vehicle and when you will need a medical report

Medical issues

Irish and EU legislation requires that a driver should advise their driver licensing authority of any long-term or permanent injury or illness that may affect their safe driving ability.

This section outlines the circumstances in which a medical report is required and the medical conditions that will preclude you from driving a motorised vehicle. It also contains guidelines “Sláinte agus Tiomáint; Medical Fitness to Drive Guidelines (PDF)” for medical practitioners to use when assessing or advising patients on fitness to drive.

When do I need a medical report?

Your driving licence application must be accompanied by a Medical Report Form (D501) if you:

  • Are applying for a driving licence in respect of a truck or bus, licence categories C, C1, CE, C1E, D, D1, DE or D1E (unless you have previously provided a medical report which is still valid)
  • Will be 70 years of age or more on the first day of the period for which the licence for any licence category is being granted
  • Suffer from any of the disabilities or diseases specified in the diseases and disabilities list.
  • Have ever suffered from alcoholism or epilepsy
  • Are a regular user of drugs or medication that would be likely to make your driving unsafe

The medical report must be completed by a registered medical practitioner and you must sign the declaration in his/her presence.

Medical guidelines “Sláinte agus Tiomáint; Medical Fitness to Drive Guidelines (PDF)”  for Group 1 licence categories AM, A, A1, A2, B, BE or W and Group 2 Categories C, CE, C1, C1E, D, DE, D1 or D1E i.e. truck and bus (with or without trailer have recently been revised and updated taking into account legislative changes made in relation to the standards for eyesight, epilepsy and diabetes, as well as internatioal best practice. The guidelines set out clear minimum medical requirements and all applicants presenting themselves for medical examination should be assessed on the basis of the minimum standards outlined.

As in the past Group 2 guidelines require a higher standard of physical and mental fitness on the part of these drivers in light of the duration of time they spend behind the wheel and the greater size and weight of their vehicles. The updated Group 2 guidelines have been drafted following a public consultation process, including associations representing Group 2 drivers.

Note:

A person who is dependent on or regularly abuses psychotropic substances, ie, those that can induce mood changes or distorted perceptions, is barred from holding any learner permit or driving licence.

A person who suffers from serious arrhythmia which has at any stage resulted in loss of consciousness is particularly advised to consult his/her doctor before applying for a licence.

If you have any doubts about your physical or mental fitness to drive you should consult a doctor.

Content of medical report

The medical report must specifically refer to your eyesight, hearing, general physique and your general medical condition insofar as it is relevant to your ability to drive. This is the case regardless of whether the report is needed for age reasons or for illness/disability reasons. If you are downloading this form(PDF) then it must be printed back to back on one page.

Appeals

An appeals mechanism is available for drivers who have been refused a licence on medical grounds. The Driving Licence Authority will inform drivers of the appeals process when informing them of the licensing decision.
