breath test problems

Hello! My hubby was pulled over at a weight station... he had NOT been drinking at all, yet when he had a breath test at the weight station, they said he blew 0.016. they sent him to the police, and was tested TWICE, and blew all clear!
Yet hubby thinks he's in trouble, because it's the weight stations' paper that are getting sent to his workplace, and NOT the police papers that showed he blew all clear.

Hubby and I are both suspicious of the man at the weight station, because when hubby blew in the machine, the man did NOT show him the results, or tell him the results right away...he took off into the building where hubby couldn't see him! so we are wondering if there are also "fishy" dealings going on

 

P.S: I told hubby I would speak to his company in his behalf...do you all think it would make things worse or better?

 

the one at the weight station was TINY, hubby said...he told me it was small enough to fit in your pocket!...but he said the one the police used was very accurate/complicated...it even showed the amount of breath you gave, showed the numbers you blew ...from what I remember hubby saying.

 

he doesn't use mouth wash, or supplements while on the road... he was very tired though, he hadn't slept well.
the weight station ticked off the box that says: "possible narcotics use/possession", even though hubby doesn't use drugs at all. He lives off coffee and cigarettes and tylenol while on the road (no codeine in the tylenol)
