In a weird and kind of scary story out of North Texas, drivers at a roadblock were asked by federal contractors to give their blood and/or saliva to test impairment.  Why?  It was surprisingly difficult to get an answer.

According to, Fort Worth drivers at a roadblock were asked to give fluids to help the National Highway Traffic Safety Administration (NHTSA) do a survey of the number of intoxicated drivers on the road.  Drivers were told they would be paid $10 for a saliva swab or $50 for a blood sample.

The NHTSA said the participation was "completely voluntary," but some drivers reported feeling coerced into giving a sample.  Off-duty Fort Worth police officers assisted with the roadblock, but when asked, the police department initially had no idea the roadblock was being done AT ALL.

Yikes, kiddos.

Were people's civil rights violated here?  After all, you can't be pulled over for having done nothing.  Does this constitute coercion?
