Diabetes and Driving

There is an important connection between diabetes and driving. If you have a low blood glucose level (hypoglycemia) while driving, this could affect your ability to drive. Hypoglycemia may cause changes to your senses, slow your reaction time and you could lose consciousness. Hypoglycemia is a blood glucose level of less than 4 mmol/L. Sometimes, when your blood glucose levels are high (hyperglycemia) it can also affect your ability to drive safely.


Your doctor will determine if you're medically fit to drive. He/she will review your blood glucose log book and see if you are managing your diabetes well, keeping your blood glucose levels in control, and can recognize and treat hypoglycemia.

Things to be aware of:

  • If you are applying for your driver's license, you must report that you have diabetes.
  • Your doctor can report you to the motor vehicle licensing agency if he/she feels you're unfit to drive due to poor diabetes control with many low blood glucose levels. This could result in a suspension of your driver's license.
  • The motor vehicle licensing agency also has the right to suspend your driver's license if you have an accident due a low blood glucose level.
  • When driving, you should measure your blood glucose level within 1 hour before and at least every 4 hours during long drives. You should always carry your blood glucose monitor and supplies in case you experience a hypoglycemic reaction. TIP: You must keep a fast acting carbohydrate (i.e., glucose tabs) within easy reach (for example, attached to the visor).
  • You should never drive when your blood glucose level is less than 4.0 mmol/L.
  • If you do have a low blood glucose level and treat yourself for it, you should wait at least 45 to 60 minutes before starting to drive again. You are not permitted to drive again until your blood glucose has risen above 4.0 mmol/L and you have taken a snack or a meal.
