What is the safe range for blood glucose levels for commercial driving?

The safe range for blood glucose levels for commercial driving is typically recognized as being between 80 and 300 mg/dL. Maintaining blood glucose within this range is important for commercial drivers, particularly those with diabetes, as it minimizes the risk of hypoglycemia and hyperglycemia, both of which can impair cognitive function and reaction times.

When blood glucose levels fall below 60 mg/dL, the risk for hypoglycemic symptoms increases, leading to confusion, dizziness, or even loss of consciousness, which can be dangerous while operating a vehicle. Additionally, levels exceeding 300 mg/dL can lead to hyperglycemia, increasing the risk of serious health complications and also affecting a driver's ability to operate their vehicle safely. Thus, the correct range represents a balance that ensures both the safety of the driver and the public.
