Hypoglycaemia (low blood sugar) can impair concentration and reaction time while driving.
Hypoglycaemia (low blood glucose) can impair concentration and reaction time, which leads to an increased risk of accidents while driving.
However, most people with diabetes who maintain stable blood glucose levels can drive safely,
The Department of Endocrinology from Singapore General Hospital (SGH), a member of the SingHealth group, shares what people with diabetes need to take note of before going behind the wheel.
If you are on insulin injections or on oral glucose-lowering tablets like sulphonylureas, it INCREASES your risk of hypoglycaemia. This is in particular if you have:
Other medications that can cause drowsiness may also DECREASE your alertness on the road and your ability to detect low blood glucose symptoms and signs.
Before you start driving, check your blood glucose level before you drive. Aim for a blood glucose level above 5.0 mmol/L.
If you are on a long car journey, check your blood glucose (BG) level every 2 hours and consider taking a break.
Test your blood glucose level if you experience symptoms of hypoglycaemia such as:
If not treated, your symptoms and signs can become more severe, and can include:
If you have these symptoms or signs, you or the people around you should call for an ambulance (995) immediately.
1. Always bring along a glucometer to monitor blood glucose readings.

2. Bring along quick and long-acting carbohydrates to treat hypoglycaemia (low blood sugar).

3. Have a Medik Awas card (see below) to identify you as a person with diabetes in the event of an emergency.

4. Always test your blood glucose levels before driving and every 2 hours into driving.

5. If your blood glucose reading is below 5.0 mmol/L, take 15g of long-acting carbohydrates before you start driving e.g.: 3 pieces of biscuits, or 1 slice of bread.

6. Protect your glucose strips from extreme temperature and direct sunlight to ensure accurate readings.

7. If you have a hypoglycaemia episode, stop by the roadside where possible and treat this immediately.

8. After treating hypoglycaemia, do not drive until you have fully recovered.

10. Never drink and drive.
1. Locate a safe place to stop and park your car.

2. Turn off the engine and shift to the passenger seat.

3. Treat hypoglycaemia (< 4.0 mmol/L) using the 15/15 Rule:
15g of quick-acting carbohydrates, wait 15 minutes and re-test to ensure blood glucose level rises above 4.0 mmol/L.

4. When your blood glucose level has reached above 4.0 mmol/L, take 15g of long-acting carbohydrates before you start driving.

Start driving only when all your hypoglycaemia symptoms are gone and you can perform tasks like mental math. You may need to wait up to 30-45 minutes.
According to the Singapore Medical Association (SMA), the Medik Awas card aims to prevent medical mishaps by alerting medical and dental personnel to any specific medical problems of registrants.
