Man, I'm also about to start a new job/school for truck driving, have to pass a D.O.T. test next week. The company web site says they use Hair focile testing that goes back 12 months, but from what I read thats probably bullshit.
ANYWAY...Question is this...Does the D.O.T accept hair testing or only urine?...All I can find in rules/regs is about urine..............I think I got the unine covered,...hair is scary. ;->
