Whether you are a driver or a passenger, checking your blood glucose regularly is very important. Check it before you leave home and then again every four hours during your journey. Stop every few hours to stretch your legs and do some physical activity. This will help improve blood circulation. At the first sign of low blood glucose or hypoglycemia, pull over to the side of the road and take a form of fast-acting sugar, such as 15 grams of glucose tablets (preferred) or 175 mL of fruit juice or regular pop. Follow this with a longer-acting carbohydrate and a protein such as a sandwich. Do not start driving again until the symptoms have disappeared and glucose values are above 6 mmol/L. If you take insulin, avoid driving in the time between your injection and your next meal. Limit your driving to a maximum of 12 hours per day, or six hours between any two meals. Keep your medication, meal, and snack times as regular as possible. You may not always be able to get to a restaurant on time, so bring supplies with you to treat low blood glucose (e.g. 15 grams of glucose tablets, six Lifesavers or 175 mL of fruit juice or regular pop) in case of traffic jams, car trouble, or wrong directions.
