According to one defence lawyer, when his client is charged with failing to provide a suitable sample, depending on the type of road side screening device that is being used, some of the areas that he will cross-examine the police officer on are:

inadequate training
all the error codes the instrument can produce
loose mouthpiece
blocked vent hole - hand was positioned over it
what sounds did the officer hear
make officer stick to his notes - each time the officer expands beyond the notes, argue that it undermines the officer's credibility and also argue lack of full disclosure
