Official guidance shows that a wide range of health issues could quietly affect whether someone is legally allowed behind the wheel.
Many drivers assume their licence is secure unless they are told otherwise. But official guidance shows that a wide range of health issues could quietly affect whether someone is legally allowed behind the wheel.
Little-known rules
The Driver and Vehicle Licensing Agency sets out detailed medical standards for motorists, covering both physical and mental health. According to DVLA guidance, as many as 189 medical conditions could potentially affect a person’s ability to drive.
Drivers are expected to take responsibility for reporting relevant conditions themselves. This becomes especially important if a health issue is ongoing or has been flagged by a medical professional.
The DVLA warns that failing to follow the rules can have serious consequences. Its guidance states: “You could be fined up to £1,000 if you do not tell DVLA about a condition that might affect your ability to drive safely. You could also be prosecuted if you have an accident.”
Conditions that count
While the full list runs into the hundreds, the DVLA identifies a smaller group of conditions that must always be declared. These are described as notifiable medical conditions or disabilities.
They include glaucoma, epilepsy, heart conditions such as atrial fibrillation or having a pacemaker, strokes, sleep apnoea, syncope or fainting, and diabetes or treatment involving insulin.
The agency says these conditions can affect vision, consciousness or physical control, which is why they must be reported regardless of how well they are managed.
More than you expect
Beyond the seven mandatory conditions, there are many others that may also need to be disclosed depending on their impact. DVLA guidance includes common issues such as anxiety or depression.
In many cases, these only need to be reported if they affect a driver’s ability to drive safely. The DVLA stresses that the effect of a condition matters more than the diagnosis itself.
Some drivers may be allowed to continue without restrictions, while others may face limits or be required to adapt their vehicle.
When driving must stop
The DVLA says there are three situations where a driver must give up their licence. These apply if a doctor advises stopping driving for three months or more, if a condition affects safe driving for at least three months, or if medical standards are no longer met.
While a case is being assessed, drivers are usually allowed to continue driving. The DVLA will then write to confirm whether driving can continue, conditions apply, or the licence must be surrendered.
What drivers should do
The DVLA advises motorists to check its medical guidance if they develop a new condition or their health changes. A full A–Z list of the 189 conditions that could affect driving is published on the Government’s website.
Drivers who are unsure are encouraged to seek medical advice and clarify their responsibilities early, rather than risk fines or prosecution later.
