EPILEPSY AND DRIVING

Whether a person with epilepsy is permitted to drive can be an emotionally charged and ethically complex issue in practice. Driving represents autonomy, employment, and dignity, and people often raise the problem at the earliest opportunity, frequently even before a diagnosis is confirmed.

Clinicians must balance empathy and autonomy with public safety and legal obligations. This tension is heightened when individuals minimise symptoms, underreport seizures, or misunderstand risks. Discussions around driving can strain the relationship between the physican and the person, especially when driving is essential for an individual’s work or caring. For physicians, supporting restrictive regulations, including occasionally breaching confidentiality, can be a morally complex decision.

In the United Kingdom, the General Medical Council (GMC), the medical regulator, supports disclosure only when a significant public risk exists and the individual refuses to self‐report. Respectful, well‐documented conversations, supported by written guidance and referrals to support services, are essential.

RISK IN EPILEPSY: EPIDEMIOLOGICAL AND BEHAVIOURAL FACTORS

UK REGULATORY FRAMEWORK: DVLA CRITERIA

In the United Kingdom, the Driver and Vehicle Licensing Agency (DVLA) classifies driving licences into two groups: Group 1, for drivers of private cars and motorcycles; Group 2, for drivers of larger commercial vehicles, such as lorries with an unladen weight exceeding 3,500 kg and buses.

In broad terms, a group 1 licence may be held if the risk of a seizure over the next 12 months is less than 20%. With some exceptions, DVLA regulations stipulate that people diagnosed with epilepsy must be seizure‐free for at least 12 months before resuming driving. In terms of driving, convulsions, absences, and pathological myoclonic jerks have the same implications.

One exception concerns sleep‐related seizures. If a person has only ever had seizures during sleep, including seizures on falling asleep and on waking, and this pattern is consistent for at least 12 months, they may be eligible to drive. This allowance reflects the lower risk posed by sleep‐only seizures to driving safety.

If an individual has a history of seizures in wakefulness, and subsequently sleep‐only seizures for at least three years, they may have a Group 1 licence even if they continue to have sleep seizures. The three years start from the date of the first sleep seizure that occurs after the last wake seizure.

The DVLA also allows individuals who have only ever had what they define as “permitted“ seizures to hold a Group 1 licence, provided seizures have occurred over a period exceeding 12 months. Permitted seizures are defined as seizures that do not impair awareness or the ability to control a vehicle, such as feelings of déjà vu, fear, or an epigastric rising sensation. Seizures with any motor or visual components are not permitted seizures. Even if an individual’s seizures meet these criteria, but if in the past they have ever suffered a seizure that impairs their awareness or ability to control a vehicle this concession does not apply.

If an individual has only had a single seizure, with normal EEG and MRI, the recurrence risk is lower, and a Group 1 licence may be reinstated after 6 months. Individuals who have had more than one seizure may hold a Group 1 licence provided they have been seizure‐free as described in the paragraphs above. If such an individual proceeds to antiseizure medication (ASM) reduction or withdrawal and a seizure occurs, driving may resume six months after the ASM has been reinstated at an effective dose. If an ASM is tapered, or a change is made that the physician considers increases the risk of a seizure, the individual should not drive during the change and for the next six months.

For Group 2, stricter conditions apply due to higher risks and the larger vehicles involved. After a single seizure, an individual must remain seizure‐free for five years and be assessed as having a risk of further seizures of less than 2% per year. For those with a diagnosis of epilepsy, a 10‐year seizure‐free period off ASM is required before a licence can be reinstated.

Driving is restricted after head injuries, even if no seizures have occurred, because of the risk of post‐traumatic epilepsy. This is particularly an issue for Group 2 licences, as the annual risk of a seizure in the following year needs to be less than 2%. There is now good data to inform decision‐making.⁶ After a head injury with focal cerebral injury, a Group 2 licence would be suspended for two years if no seizures occurred. After craniotomy and cerebral surgery, a Group 2 licence is suspended for five years.

Decisions on driving depend on an assessment and medical confirmation that the seizure pattern poses an acceptable risk to public safety. It is best practice to obtain corroborating evidence, including written accounts from partners or individuals who know them well.

These criteria and regulations are detailed in the DVLA’s ‘Assessing Fitness to Drive – a guide for medical professionals’, which is regularly updated online (see Further reading). Health care professionals must remain up to date with these regulations.

LEGAL AND PROFESSIONAL RESPONSIBILITIES

In the United Kingdom, individuals are legally required to notify the DVLA of any condition that affects their driving. Clinicians have a role in ensuring that individuals are aware of this requirement and understand the potential legal implications of non‐disclosure.

Confidentiality is a core value in medicine, but is not absolute. According to GMC guidance, clinicians may breach confidentiality to protect others from serious harm, including death or significant injury.⁷

Before breaching confidentiality, clinicians must consider:

• The gravity of risk to the public
  
• Whether the person refuses to notify the DVLA despite understanding the risks
  
• The harm to trust and the therapeutic relationship
  
• Whether outcomes can be achieved less intrusively

Where possible, the clinician should:

• Make all reasonable efforts to seek consent from the person
  
• Inform the person of the intention to disclose
  
• Document all communications and reasoning
  
• Consult with a Caldicott Guardian or senior adviser

Disclosure should be seen as a last resort, appropriate only when risk to others is imminent and the at‐risk driver remains unwilling to act.

INTERNATIONAL COMPARISONS

Approaches to medical fitness to drive vary globally:

• United States & Canada: States and Provinces often mandate physician reporting, placing the burden on the clinician to notify licensing bodies
  
• Australia: Use hybrid models—physicians provide assessments, but individuals share responsibility
  
• United Kingdom & EU countries: Places legal responsibility primarily on the individual

Each system reflects a balance between autonomy, safety, and the clinician–person relationship. Physician‐led reporting may reduce risk but can undermine trust, particularly in private healthcare systems. The United Kingdom’s autonomy‐based approach requires clinicians to develop effective communication strategies and carefully assess capacity.

EMERGING CHALLENGES AND FUTURE OPPORTUNITIES

Driving and epilepsy are evolving in light of new technologies. Autonomous vehicles offer a potential future in which medical fitness to drive may become irrelevant. Current systems, however, still require human oversight, and questions about legal responsibility remain unresolved. Seizure‐detection devices, capable of triggering automatic braking or alerts, are in development but not yet standard. Meanwhile, the growing popularity of electric scooters and bikes among people with chronic illnesses presents regulatory gaps. These vehicles are faster and heavier than traditional bicycles but less regulated, raising fresh challenges for medical and legal frameworks.
