Before to many of you embrace the prospect of Pre-flight breath testing, consider this. It may not be the test itself that may cause you problems, but the skill (or lack of) or interpretation of the Human Tester. Do you have faith that those appointed to carry out these test's will be paid for, and have the very highest of qualifications available that you and your Licence deserve, or will it be Low cost testing with an acceptable margin of error. Inevitably hurriedly introduced, using half-thought measures and potential mistakes.
We have all read and heard about erroneous breathalyser test's applied to Motorists, imagine this same/similar style of testing when your career is directly "on the line". The implications of this are far reaching and a little more serious than "sounds OK to me"
If you disagree, see above how facts can be manipulated when one has an agender to fullfill.
