Yes, most people with a neurological or mental health condition in Ireland can keep driving. The rules depend on the condition and how it affects you, not on the diagnosis alone. Ireland's medical standards are in Sláinte agus Tiómáint, the Medical Fitness to Drive Guidelines. The Road Safety Authority (RSA) and the National Office for Traffic Medicine publish them. The current edition is dated April 2026, updated 25 May 2026.
You must tell the National Driver Licence Service (NDLS) about any long-term condition that may affect safe driving. Where a medical report is needed, your doctor completes form D501 in person. Some conditions mean a set time off driving, such as after a seizure or stroke. Others, such as anxiety or depression without major symptoms, need no time off under the guidelines.
This guide covers what the guidelines say for epilepsy, stroke and TIA, ADHD, depression, psychosis and bipolar disorder, dementia and sleep disorders. It also covers insurance. It applies to Group 1 licences (car, motorcycle and tractor) unless stated.
The guidelines set out three duties for drivers:
When you apply for or renew a licence, the D401 form asks about 23 listed medical conditions. If you have one, the NDLS needs a medical report before it decides.
You can update your medical details in person at an NDLS centre. You may be able to do it online if you have a Public Services Card and a verified MyGovID account. The NDLS cannot accept notice of a medical condition by email or post.
The guidelines also warn that not reporting a relevant condition can have "long-term financial, insurance and legal consequences".
The D501 is the medical report form used for all medical conditions. It is usually completed by your GP, sometimes after advice from your consultant.
A few practical points:
The restrictions a doctor can indicate on the D501 include:
The final licensing decision rests with the NDLS. If you are refused a licence on medical grounds, there is an appeals process. The NDLS tells you how to appeal when it gives its decision.
The list summarises Group 1 standards from the April 2026 guidelines. It is a starting point for a conversation with your doctor, not a decision about you.
The guidelines call epileptic attacks "the most frequent medical cause of collapse at the wheel". The epilepsy rules count all seizures, including minor ones, auras and absences. Several seizures within 24 hours count as one event.
After a seizure while awake, you must not drive for at least one year. Some situations are treated differently, each with conditions:
After a transient ischaemic attack (TIA), the standard is one week off driving. After a stroke, it is four weeks. You need to tell the NDLS only if a significant problem remains after four weeks. The guidelines highlight visual field loss, cognitive problems, neglect and impaired limb function. Minor limb weakness alone does not need notifying unless you need adapted controls.
If you are worried about stroke symptoms, our guide to the warning signs of stroke explains when to call for help.
ADHD on its own is not a bar to driving. The guidelines say impulsivity and a lack of awareness of the impact of your behaviour should be considered. They also state that taking medication as prescribed "is associated with reduced crash risk in ADHD". They single out alcohol and drugs, which "substantially increase the risk of crashes with ADHD".
The guidelines list ADHD medication among medicines that "may actually make driving safer". For what stimulants do and their side effects, see what ADHD stimulants actually do.
You may drive if your anxiety or depression does not cause major symptoms. The guidelines list significant memory or concentration problems, agitation, behavioural disturbance and suicidal thoughts. You need not tell the NDLS unless a doctor advises you to stop for six months or more.
If symptoms are more severe, you should not drive until a doctor has assessed you. The guidelines note that "it is the illness rather than the medication" that matters most. Medication must not affect alertness or concentration. Driving is "usually permitted" when long-standing anxiety or depression is controlled on non-impairing doses.
If you are having thoughts of suicide, please do not drive. Call 112 or 999, or contact Samaritans free on 116 123, any time.
You should not drive during an acute psychotic episode, or during mania or hypomania. Driving can be considered again when you have stayed well and stable, with insight and engagement with your care team. Medication must not cause side effects that impair driving.
For repeated changes of mood, the guidelines advise a specialist opinion from a consultant psychiatrist. Continuing psychotic symptoms do not automatically rule out a licence. Symptoms that involve other road users are described as "particularly dangerous".
Dementia does not automatically end driving. The guidelines say people with poor short-term memory, disorientation, or loss of insight and judgement are "almost certainly not fit to drive". In early dementia, a licence may be issued with annual or more frequent review. Safe driving is "unlikely" with moderate dementia. If someone with dementia keeps driving, the guidelines advise reassessment every 6 to 12 months, with a low threshold for an on-road driving assessment.
Mild cognitive impairment without objective loss of everyday function does not need to be reported. Yearly review is recommended.
Moderate or severe obstructive sleep apnoea that causes excessive sleepiness means no driving until symptoms are controlled. Treatment must be confirmed by a specialist, and you must tell the NDLS. For CPAP users, the guidelines look for use of more than four hours a night. If you are unsure whether you have sleep apnoea, our STOP-BANG guide explains the screening questions.
For narcolepsy and similar conditions, driving can resume after three to six months of good symptom control on treatment. Read more in our article on why narcolepsy takes years to diagnose.
The guidelines group autism with "developmental disorders". A diagnosis "is not in itself a bar to licensing". The Group 1 entry ends: "Driver should notify NDLS."
Any medicine that acts on the brain can affect driving. The guidelines say the risk is highest when you start a medicine or change the dose. You must not drive if a medicine makes you drowsy or otherwise impaired.
The guidelines name benzodiazepines as the psychiatric medicines most likely to impair driving, and say alcohol makes this worse. Driving while impaired by any drug, including a prescribed one, is an offence under the Road Traffic Acts.
The guidelines also say people with psychiatric illness are often safer drivers when well and on regular medication. Your prescriber or pharmacist can tell you how a specific medicine may affect you.
Group 2 standards are much stricter. After epilepsy, for example, you need 10 years seizure-free without epilepsy medication. Employers can set higher standards still.
The RSA guidelines advise drivers to tell both the NDLS and their insurer about any long-term condition that may affect safe driving. They also warn that ignoring medical advice to stop driving may affect your insurance cover.
Irish insurance law sets out your duty to the insurer. Under the Consumer Insurance Contracts Act 2019, you must answer the insurer's questions honestly and with reasonable care. The insurer must ask specific questions, not general ones. At renewal, the same applies to any specific questions the insurer asks.
Policies differ. Read your policy wording, and ask your insurer or broker in writing what they need to know. Keep a copy of what you send. If an insurer refuses a claim, Citizens Information or a solicitor can advise you.
Your doctor has a duty to advise you on driving after a relevant diagnosis. Useful questions include:
Doctors keep your information confidential. The guidelines allow a doctor to report directly to the NDLS or Gardaí only in rare cases. An example is a driver who is a risk to others and ignores advice.
In Great Britain, the licensing agency is the DVLA, and the rules differ in detail. DVLA guidance says:
Check gov.uk for your specific condition.
No. The guidelines allow driving after at least one year without seizures while awake, with yearly licences at first. Separate rules apply for sleep-only seizures and seizures that never affect awareness.
The ADHD entry in the guidelines does not set a fixed time off driving. Ask your prescriber whether your situation needs declaring, ideally before your next renewal.
No. The guidelines and the National Office for Traffic Medicine say the D501 must be signed in front of the doctor, in person.
Encourage them to talk to their GP, and go with them if they agree. The guidelines advise starting conversations about stopping driving as early as possible. If you see dangerous driving, you can report it to the Gardaí.
