On most days I'd fail a roadside breathalyser because they're a load of crap.

De-arrested while they wait for the test to be analysed, it takes a couple of weeks to come back so he will probably still be charged.

And the roadside breathalyser is sensitive enough to be used for airline pilots with a much lower tolerance than driving offences, the station procedure is a throwback to the crystal in a bag days and will probably be scrapped in the near future.
