3. Manage any chronic conditions

Work with your doctor to manage any chronic conditions — especially those that might impact driver safety, such as diabetes or seizures. Follow your doctor's instructions for managing your condition and staying safe behind the wheel. This might include adjusting your treatment plan or restricting your driving.

It's equally important to know your medications. Many drugs, including pain medications, sleep medications, antihistamines and muscle relaxants, can affect driver safety, even when you're feeling fine. Read your medication labels so that you know what to expect from each one.

Don't drive if you've taken medication that causes drowsiness or dizziness. If you're concerned about side effects or the impact on driver safety, consult your doctor or pharmacist.
