Hypos and driving
The licensing agencies are trying to ensure you are safe on the road. They will be concerned if you are unable to recognise or self-treat your hypos.
If you are on insulin, check your blood glucose within two hours before getting behind the wheel and every two hours whilst driving.
The DVLA advise that if blood glucose is 5mmol/l or less you should take carbohydrate before driving. If it is less than 4mmol/l do not drive. See advice below on hypo advice for drivers.
If you hold a Group 2 licence and take non-insulin medication which may cause a hypo you should check your levels at least twice per day at times relevant to driving. The results should be recorded on the meter memory.
