Now you’ve been diagnosed with gestational diabetes does this affect driving?

Did you know that all women diagnosed with gestational diabetes should contact their vehicle Insurance providers to inform them of the diagnosis? Many companies may say it’s fine and that they do not need to know, but we advise that you get them to put a note on their system to protect yourself should you need to make a claim as by law it is YOUR responsibility to disclose this information. Informing your insurance provider should not affect your premium.

DVLA notification

Diet or Metformin-controlled GD

If you control your gestational diabetes by diet or metformin, you do not need to notify the DVLA of your diagnosis.

GD and DVLA notification - diet
Insulin-controlled GD

If insulin is used to control your gestational diabetes it is classed as temporary insulin treatment. Group 1 (Car and motorcycle) users only need to inform the DVLA if you will be using insulin for 3 months or more, or if you continue to use insulin following the birth of your baby (i.e. you are diagnosed with type 1 or 2 diabetes following birth) for 3 months or more.

Group 2 drivers (Bus and lorry) must notify the DVLA as soon as insulin treatment is started

Driving & gestational diabetes when using insulin – “five to drive”

If you use insulin or glibenclamide to control your blood sugar levels then you are at risk of hypoglycaemia. Due to this risk, you should test your blood sugar levels before driving, every time you drive. It’s advisable for your levels to be 5.0mmol/L or above before driving. Remember this phrase “five to drive.”

If you test and levels are below 5.0mmol/L then you should eat a snack which is suitable for the GD diet, which will raise levels slightly but not enough to cause hyperglycaemia (high blood sugar levels).

If at any point whilst driving you feel unwell, you should stop your vehicle in a safe place and test your blood sugar levels to check for hypoglycaemia.

Leave yourself 15 mins before leaving to test and eat if needs be. Good foods to try for raising levels without spiking blood sugar levels too high are things like 2 Nairns oat biscuits or a Granny Smith apple and a handful of nuts to pair.

If you are diet or metformin controlled you do not need to test blood sugar levels before driving unless you feel unwell.
