What is the medical examiner certificate expiration date? Examination 11/16/2011; disqualified due to diagnosis of benign positional vertigo last episode 10/11/2011; return to medical examiner's office for complete new certification examination on 1/2/2012. Note asymptomatic since 10/11/2011 - driver qualified for two years. Expiration date 10/11/2013. Expiration date 1/2/2013. Do not certify - waiting period has not been completed. Expiration date 1/2/2014. - ✔✔Expiration date 1/2/2014. Explanation: The certification date is always based on the date of the last complete examination. The waiting period for benign positional vertigo is two months symptom free. Additional tests above and beyond what are necessitated by the examination process should be performed only when ____________. The examination was unable to determine if the driver passed one or more requirements. The examination was unable to determine if the driver passed a majority of the requirements. The driver requests that additional tests be run. Requested by the driver's employer. - ✔✔The examination was unable to determine if the driver passed one or more requirements.

Driver Examination 2/17/2012, blood pressure 144/102. Driver given three-month certification to 5/17/12. The driver returns on 3/16/12 with blood pressure of 124/82. The next step for the medical examiner is? Perform a complete examination and certify the driver for one year if the driver passes the examination. Certify the driver for one year from 2/17/12. Require the driver to return for additional blood pressure checks since the blood pressure still does not meet certification requirements. Disqualify the driver. - ✔✔Perform a complete examination and certify the driver for one year if the driver passes the examination. Explanation: The driver's blood pressure meets certification requirements. Given the previous elevated blood pressure, with respect to blood pressure guidelines the driver now qualifies for a one year certification. However, a complete examination is required each time a new certification interval has been designated, so a complete examination is now required and the date of expiration should be determined from the last date of full driver examination. The medical examiner's role in the exemption process includes _________. Issuing the exemption. Issuing the prescription for the driver's contact lenses and/or glasses. Providing the driver with contact information for the Federal Vision Exemption Program. Assuring that the driver has peripheral vision of at least 110 degrees in each eye. - ✔✔Providing the driver with contact information for the Federal Vision Exemption Program.
