Driving for Work: Mythbusters
52 common misconceptions – and the facts employers and drivers need to know
Myth 47: I only have to declare medical conditions when renewing my licence
Drivers have a legal obligation under DVLA rules to report any medical condition that affects their ability to drive as soon as it develops – not just at licence renewal.
Conditions such as epilepsy, sleep apnoea, sudden loss of consciousness, seizures, certain heart conditions, diabetes managed by insulin, and significant vision problems must be declared promptly.
Failing to report a relevant condition is a criminal offence and can invalidate insurance.
Employers should make drivers aware of this obligation and include it in driver declarations. A culture of openness about health matters supports safe management and protects both the driver and the organisation.
Driver takeaway:
You are legally required to report a new or worsening medical condition to DVLA as soon as it develops – not when your licence comes up for renewal. Failing to declare is a criminal offence and can invalidate your insurance. If in doubt, check gov.uk or speak to your GP.
Manager takeaway:
Include medical declaration obligations in your driver induction, annual declarations, and regular communications. Create a culture where drivers feel safe raising health concerns.
An employee who withholds a medical condition and is later involved in a collision creates serious legal exposure for both themselves and the organisation.
