Should police cars have cell phone snifferes that can tell when you are on the phone when you drive by? Maybe have check points to check you text logs on the phone? Should police set up blood draw check points to test for drug (legal or illegal) levels in your system?
Latest campaign in Oz is for driver fatigue, which is being acknowledges as worse than drink or drugged driving in terms of contribution to the road toll...I've driven home from work after 29 hour shift, and I can tell you that I agree.
When the power industry was bringing in impairment testing, our sister site decided to go the whole way, and brought in a "track ball" impairment tester.
Before you could access site at start of shift, you had to use a track ball to guide a dot around a maze...you trend was recorded, and if you failed (either worse, or better, as some drugs would make you better), then it was blow the bag and get a swab.
We all thought is was great, as Management pro-actively allowed it to be used prior to or during overtime to assess whether you were fit for the extra shift, or even to drive home after a long shift.
Problem was that 6% of people failed every morning, requiring intervention, and over months, they only picked up one person over the limit for BAC. Every fail required a manager to do an assessment/testing before they could gain access to site.
Company explained that 6% was the statistical norm, depending on decent sleep, stress, any number of factors.
The campaign, although very well intentioned, was dropped for Random Breath tests and cheek swabs, which are now the norm in the power industry.
The take home was that 6% of the people who drove to work were impaired enough to draw attention in a highly developed "sobriety test" without actually having a chemical in their system.
And roadblocks for DUI, netting 0.1% aren't going to change it.
