After the physical examination is complete, Dr. Williams will discuss any medical condition from your past and current medical conditions, which could affect your ability to drive. Based on your past and current history, as well as the findings on the physical examination, Dr. Williams will determine the certification period and issue a Medical Examiner’s Certificate.

If the certified medical examiner determines that you meet the criteria for a medical certification without limitations, you will be issued a medical certificate for two years.

The certification period is determined by FMCSA DOT criteria based on your past and current medical history, as well as current physical findings on your examination and you may qualify for a certification period of less than two years.

If you wear corrective lenses, and you pass the vision portion of the exam, the medical examiner will issue you a Medical Certification to drive with a corrective lens indicated.

Dr. Williams will give you every opportunity to take corrective action in order that you may be given a temporary CDL license.
