0.02 is the limit in Europe. I have been tested in Norway, Sweden and Holland.
You fail the test, you will be asked to rinse your mouth and test again. Fail again, you go to the office for a blood sample.
You will not be over the limit if you drink two pints 8 hours before duty. It takes more than that.
This is turning into a Norway bashing exercise. Are you saying if you get tested in the UK and the initial result is 0.04, they will pat you on your shoulder and send you on your way?
Nope, they will do the same as in this case.
The test results will be out soon.
