Great question! Sorry for the delay this one stumped me too. I looked and couldn’t found a pound lifting requirement anywhere. I’ve always been told not to pass with any kind of restrictions. I did ask Dr Hartenbaum to weigh in and this is her response:
” The answer is complicated. There is no ONE specific number but a lot of resources examiner should use to evaluate whether the individual can perform ALL potentially required duties of a CMV operator. MEs must remember that a certification is good for ANY CMV operations/ company and the ME cannot place any restrictions aside from corrective lenses/s hearing aid or SPE or other variance (exemption or certification under an alternative standards
Sources MEs should consider.
The CMV driver demands and duties found in the ME handbook not once, but twice. Section 3.3 and Section 4.9.3.1
The Introduction to the Medical Examination report form is another good portion to consider.
Truck Driver - heavy (remember the certificate is good whether the individual drivers a bakery truck weighing 11K pounds but the bread crosses state lines or a vehicle weighing well over 26 K and being required to load and unload.) is generally considered a medium to heavy job.”
