Immediate unsafe driving or work
A person who is severely intoxicated, psychotic, manic, suicidal, cognitively impaired, sedated or sleep deprived and intends to drive or operate hazardous equipment now may present immediate danger.
Action: Advise immediate cessation, prevent access to vehicle or machinery through safe proportionate measures, arrange urgent clinical treatment and involve emergency services when danger cannot otherwise be contained. Seek consent to involve a supporter or employer where appropriate; if refusal leaves others at risk of death or serious harm, follow GMC disclosure guidance and document the minimum necessary sharing.
Synopsis
Assess how psychiatric symptoms, cognition, substances and treatment affect driving and safety-critical work, give current licensing advice, support proportionate occupational adjustment and disclose without consent only when a serious-harm or legal threshold justifies it.
Ask about licence type, vehicle, professional driving, recent incidents, near misses, sleep, cognition, impulsivity, psychosis, mood, substances and medicine effects.
Use the current DVLA medical-professional guidance for Great Britain or DVA route in Northern Ireland because standards differ by condition, severity, treatment and licence group.
Advise the patient clearly when they must stop driving and when they have a legal duty to notify the licensing agency, recording the exact discussion.
Key red flags
Suicidal intent involving a vehicle, deliberate collision, driving to a lethal location or transporting a weapon requires emergency risk management beyond ordinary licensing advice.
