Driving

Diabetes can affect your ability to drive safely because of the risk of hypos, so there are some guidelines that are important to follow:

You should check your blood glucose regularly when driving.

Before, after and while you drive, your blood glucose level should always be above 5 mmol/L.

If your glucose is 5 mmol/L or less, eat a snack.

DVLA Guidelines (updated February 2019)
If you are using an isCGM or rtCGM device, you must do a fingerprick check if:

Your blood glucose level is 4 mmol/L or below

You have symptoms of hypoglycaemia

Your glucose monitoring system gives a reading that is not consistent with your symptoms (i.e. you have symptoms of hypoglycaemia but your system does not indicate this)

You are aware that you have become hypoglycaemic or have an indication of impending hypoglycaemia
