But in case of a technology error or connection failure, testing blood sugar levels remain a top priority before getting behind the wheel of a vehicle. Keep a glucometer kit on hand for emergencies.


Low blood sugar levels while driving can lead to a potentially dangerous situation. As symptoms of shakiness and fatigue worsen, a person’s level of confusion will increase.

Numbers to commit to memory.

  • Symptomatic hypoglycemia is glucose levels that are less than 70mg/dL.
  • Significant hypoglycemia is a glucose level of less than 54mg/dL.

Take action.

  1. If the blood glucose result is low, immediately address it by consuming 15 grams of a high-carbohydrate snack or beverage.
  2. Wait at least 15 minutes after ingesting the food or drink to assess mental and physical status, then recheck sugar levels.
  3. Another 15 grams of carbohydrate may be necessary if blood sugar has not risen sufficiently; wait another 15 minutes to access results.
  4. Always wait long enough to ensure blood sugar levels are stable in the normal range before starting to drive to avoid any hypoglycemic symptoms when driving.

Possible hypoglycemia causes.

  • Meglitinides.
  • Sulfonylureas.
  • Insulin (bolus or basal).
  • Low carbohydrate meals and snacks.
  • Alcohol.
  • Planned or unplanned physical activity.

Emergency reserves.

  • Keep a selection of regular sugar candies and sugar packets and keep them in an easy-to-reach vehicle compartment.

Regular sugar enters the bloodstream raising blood levels quickly and helping a person regain stability, therefore, enough time to get into a safety zone such as a convenience store, restaurant, or call for help/911.

  • Glucometer kit.
