I am a type 2 diabetic who holds a commercial drivers license. I had my required DOT physical and passed with flying colors and received my medical card for 1 year. 2 years is normal but 1 year is common for someone in my situation. However 3 weeks later I received (via my company's safety director) a new card valid for only six months. Seems the company's contracted medical examiner contacted my personal physican and obtained my medical records.He then changed my medical clearance from 1year to 6 months without a new exam.I know I have signed a paper at my doctor that only allows my records to go to my wife and insurance provider.Who is in violation here?
