      2. Exercise Stress Test
  3. Significant Respiratory Disease
    1. Oxygen therapy while driving is disqualifying
    2. Spirometry indicated for significant symptoms
    3. Spirometry findings requiring oxygenation assessment
      1. Forced Expiratory Volume (FEV1) <65% of predicted
      2. Forced Vital Capacity (FVC) <60% of predicted
      3. FEV1 to FVC ration <65% of predicted
    4. Oxygenation assessment
      1. Arterial Blood Gas (ABG) indicated for O2 Sat <92%
      2. Disqualifying Arterial Blood Gas values
        1. PaO2 <65 mmHg
        2. PaCO2 >45 mmHg
  4. Obstructive Sleep Apnea
    1. Consider screening with Sleep Study all patients with BMI >30 to 33 mg/kg2
    2. Temporary certificate (e.g. 3 months) could be offered during evaluation
  5. Uncontrolled Hypertension
    1. Maximum of 1 year for recertification once Blood Pressures have been identified as elevated
    2. Initial Blood Pressure (may take several readings)
      1. Disqualifying Blood Pressure: >180/110 mmHg
        1. Recertify for 6 months from date when <140/90 and then every 6 months
      2. Temporary Certification (3 months): >160/100 mmHg
        1. One time certificate for 3 months
        2. Recertify for 1 year when <140/90 mmHg
      3. Temporary Certification (3 months): >140/90
        1. One time certificate for 3 months
        2. Recertify for 1 year when <140/90 mmHg
    3. Treated Hypertension
      1. Consider sudden collapse risk if end organ damage
      2. Certify for only one year at a time if <140/90 mmHg
  6. Disorders that alter driving ability or judgment
    1. Disqualification per physician assessment
    2. Examples
      1. Musculoskeletal, neurologic or vascular disease
      2. Narcolepsy (typically disqualifying with or without medication)
      3. Psychiatric illness
        1. Judgment or reality perception affected
