In the UK, driving after receiving an ICD is governed by DVLA regulations, not solely by your doctor’s assessment.
For Group 1 licences (car and motorcycle), a driving ban of at least six months typically applies following ICD implantation. If your ICD delivers a shock that causes or could have caused incapacity, a further period of restriction applies. Once the restriction period has passed and your cardiologist confirms your condition is stable, you can usually resume driving.
For Group 2 licences (lorries and buses), the restrictions are much stricter. Having an ICD typically results in permanent revocation of a Group 2 licence in most circumstances. This can have significant implications for professional drivers.
You are legally required to notify the DVLA and your motor insurer. Your cardiologist or device clinic will advise you on when it is medically appropriate to resume driving, but the final determination is made by the DVLA. Always check the most current guidance at www.gov.uk/dvla/medicalenquiries.
