Synopsis
Assess whether cognition, vision, movement, episodes of impaired awareness and medicines affect driving, give clear current DVLA advice, protect public safety proportionately, and preserve autonomy through vehicle adaptation, formal assessment and mobility alternatives.
- Age alone neither removes nor guarantees driving fitness; assess the medical condition, real driving function, licence group, vehicle and current DVLA rules.
- Dementia must be notified to DVLA; diagnosis does not by itself determine an identical outcome for every Group 1 driver, because severity and functional safety matter.
- First-line review uses collateral driving history, cognition including attention and visuospatial function, vision, neck and limb control, reaction, episodes of impaired awareness and medicines.
- Ask specifically about getting lost, dents, near-misses, lane position, junction errors, speed, family concern, night avoidance and police or insurer contact.
- No single cognitive screen is a gold-standard driving test; low scores, executive or visuospatial errors and impaired insight inform referral and immediate safety judgement.
- A specialist on-road driving assessment is the functional reference evaluation in selected uncertain cases, often combined with off-road cognitive, visual and physical testing.
- Advise immediate cessation after unexplained loss of consciousness, seizure, acute stroke, delirium or other dangerous impairment and apply the exact current DVLA rule for cause and Group 1 or 2.
- The driver is responsible for notifying DVLA of relevant conditions; clinicians must explain, document and check understanding, involving family with consent where appropriate.
- If the patient keeps driving against advice and creates serious risk, GMC guidance permits necessary relevant disclosure to DVLA after attempts to persuade and advance warning where practicable.
- Plan mobility before cessation: family and community transport, bus pass, taxi or volunteer schemes, delivery services, vehicle adaptation and benefits assessment can preserve participation.
Key red flags
A blackout, seizure, acute stroke or new focal deficit requires immediate medical care and no driving while the relevant DVLA criteria are addressed.
Getting lost on familiar routes, collisions, near-misses, lane errors or confusing pedals indicates unsafe function until formally assessed.
Delirium or rapidly fluctuating cognition invalidates routine office fitness assessment and requires cessation and cause treatment.
New diplopia, field loss or inability to meet legal visual standards requires cessation and ophthalmic or optometric assessment.
Daytime sleep attacks, severe untreated sleep apnoea or sedative toxicity creates immediate driving risk.
Refusal to stop despite clear dangerous impairment triggers documentation, senior advice and possible proportionate disclosure under GMC guidance.
Delirium, intoxication or rapidly fluctuating illness requires cessation and treatment rather than a routine office clearance.
Blackout, seizure, hypoglycaemia or sleep attack requires immediate cessation and diagnosis-specific DVLA review.
Continued driving despite informed unsafe advice may require proportionate disclosure after GMC steps.
Investigation priorities
Identify real-world errors and compensation first line.
Management branches
A condition, family concern or functional change raises driving questions.
- Clarify licence group, condition, real-world driving, collateral, cognition, vision, physical control and medicines.
- Check the current DVLA professional standard for the exact diagnosis and decide whether immediate cessation is required.
- Explain notification, document advice and arrange treatment, formal assessment or review with a named owner.
