Overview

• Recent reports cite research estimating that about 10.3 million people in the UK have medical conditions that may require notifying the DVLA to keep driving legally.
• Failing to declare a notifiable condition can lead to fines of up to £1,000, possible licence revocation and prosecution if an undeclared issue contributes to a crash.
• Drivers are advised to inform their insurers about relevant health conditions, as nondisclosure can invalidate cover.
• Condition‑specific rules highlighted include declaring insulin treatment lasting more than three months, stopping and reporting if sleep apnoea causes excessive daytime sleepiness, notifying when glaucoma affects both eyes or vision falls below DVLA standards, and reporting certain cancers when diagnosis or treatment affects driving fitness.
• After a pacemaker implant, motorists must stop driving and can usually resume after one week if no complications are present; commercial drivers starting insulin must obtain official clearance, and doctors may advise voluntary licence surrender when told not to drive for three months or more.
