I join my colleagues in welcoming all of you here today. I do appreciate the testimony you've given and I have a lot of questions that I don't think six minutes will quite cover, but we do know that when we talk about public safety embedded in that conversation is also the safety of the workers who work within the industry.
I do want to go back to the discussion around fatigue management, even though I also want to ask you questions about the use of remote-controlled devices.
Briefly, you mentioned the mileage-based system. How long has that system been in place?
