Check you're safe to drive


If you get the warning symptoms of a hypo whilst driving, you must always stop as soon as it is safe to do so. Do not ignore the warning symptoms.

When you are driving you should:

  • always carry your blood glucose meter and strips with you
  • carry personal identification to show you have diabetes in case of an accident
  • never drink and drive
  • make sure your blood glucose meter displays the correct time and date so you have a record

If your blood glucose is 5.0 mmol/l or less, have a snack. If it is less than 4.0 mmol/l or you feel hypoglycaemic (low blood glucose), do not drive.

Legal requirements

Legally, if you have diabetes and you drive you need to:

  • check your blood glucose is above 5mmol/L before driving
  • check your blood glucose every 2 hours if you're on a long journey
  • carry a glucose meter, hypo treatment and carbohydrate snacks like a cereal bar or banana when driving

Read more about how to check your blood glucose levels.

If you feel your levels are low

① Stop the car when it's safe

② Remove the keys from the ignition

③ Get out of the driver's seat

④ Check your blood glucose and if low, treat your hypo

⑤ Do not drive for 45 minutes after you start to feel better

Insurance, driving license and type 1 diabetes

You need to let your insurance company and the National Driving License Service (NDLS) know you have type 1 diabetes. This will not stop you driving, they just need to know you're on insulin.

There is more information in the NDLS booklet Diabetes and driving (PDF, 8 pages 584KB)
