If you enjoy driving, your dream job might involve having a commercial driver's license. You may have already gone to school for driving big trucks or you may be thinking about doing so. Once you have the certificate in hand, you will need to pass a Department of Transportation (DOT) physical. If you are diabetic, this can create a problem. Here are a few things you need to know about diabetes and passing the DOT physical.


If you are taking oral medications to control your blood sugar levels, be sure to take them with you to the physical. You should also take a copy of the prescription. If you require insulin to control your diabetes, you will not pass the DOT physical. However, you can apply for a waiver. This will require special clearance from your primary care physician and an endocrinologist.


This lab test shows the average of your blood sugar levels for the preceding three months. This report must show that you have an HBA1C of lower than 10 percent to pass the exam and receive a one-year license. If your HBA1C is between 10 and 12 percent, you may qualify for a three-month license. This will give you time to get better control of your blood sugar and have the lab work done again. If it is then under 10 percent, you will be given a nine-month license to complete the year.

Other Considerations

Controlling your blood sugar will also reduce the chance you develop other problems related to diabetes, which can cause you to fail the DOT physical. These include macular degeneration and peripheral neuropathy. Even if you do not show signs of macular degeneration yet, poorly controlled glucose levels can have an effect on your eyesight. Make sure you have an eye exam before going for the physical. If you need prescription eyewear or a new prescription, be sure to have the new glasses or contacts with you.

Diabetes is a health condition that requires constant interaction from you to prevent symptoms that make it dangerous for you to drive. The DOT needs to be sure you are not going to pass out or become disoriented or confused when you are behind the wheel. You also need to be able to see properly and have good feeling in your hands and feet to operate a vehicle safely. If you have diabetes and want to have the sweet job of being a commercial driver, follow your doctor's orders and keep your blood sugar under control at all times.
