On this week's Drilling Deep, P. Sean Garney of Scopelitis Transportation Consulting looks at the recent federal guidelines for hair testing to determine if a driver, or a potential driver, has drugs in their system.

And Garney wonders: will this ever get off the ground to become an industry standard? He'll talk about why he's skeptical.

Also on this week's episode, host John Kingston looks at how some numbers in the diesel market are eye-popping, but the market for oil overall is so weak that it's possible nobody will notice.
