Final answer:
The driver physical qualification standards are contained in regulations updated with the final rule signed on October 1, 2015, effective December 28, 2015.
Step-by-step explanation:
The driver physical qualification standards are cited in regulations that outline the health requirements drivers must meet to ensure they are able to operate commercial motor vehicles safely. A final rule was signed on October 1, 2015, and made effective on December 28, 2015. The standards set forth in 2008 (2008 standards) are still in effect in certain areas, despite the newer 2015 standards.
The transition from 2008 standards to the current 2015 standards will occur according to the implementation rule of the 2015 standards. This means that there is a period wherein both the 2008 and 2015 standards may apply, depending on specific circumstances or regions. Ultimately, all drivers will need to comply with the current (2015) standards once the transition is complete.
