[WHISTLED]

Having some oexperience (from mate I should add)..

This is what would have had to happen..

Pulled over and failed breath test,
Arrested and taken to the police station, second breath test failed
Charged with being under the influence and bailed to appear before magistrates at a later date (unlikely next day by appointment?!)
Appears before magistrates given points and a 12 month+ ban

Cars would not be impounded if it was at him home as stated unless he was driving without insurance etc.

I suspect this chap may already banned for something and has been caught driving, the police often go to see if a banned driver is driving.

Regarding the sweepersm etc, I dont believe they would require a driving license to operate, they would be covered in standard liability insurance, however it may be in his contract that he needs a driving license
