Driving with diabetes: the automatism defence.

The tragic case of a district nurse killed when a car driven by a man in a hypoglycaemic state struck her while she took her regular evening walk highlights the dangers that can occur when a person with diabetes drives without regard to their condition. The man was later jailed for four and a half years for causing death by dangerous driving having been found criminally responsible for his actions because he failed to control his blood sugar levels during the journey. In this article the authors set out the likely consequences for people with diabetes who fail in their duty to ensure that they are able to drive safely and are unlikely to be affected by the adverse effects of their illness or the medication taken to control it.
