No doubt that complying with appropriate regulations is generally considered a good thing.
On occasion I may choose to "bend the rules" a bit. Sometimes I drive 63mph in a 60mph zone or I may even drive a 63' rig through a state with a 60' max. If the states that I regularly drive in required the endorsement I would certainly have it. However, it is not required here.
Amazingly, my air brakes worked fine driving the Rockies, Bitteroot, and San Juan Mountians even without the benefit of an endorsement.
