It makes me wonder how breathalyzers work. If you fail, I assume the police still need to analyze a urine sample to prevent false positives. But probable cause is established with a breathalyzer failure.

This is either an standard field sobriety test (walking in a straight line, touching your nose, etc) or a screening breathalyzer. If the person fails, they are arrested and taken to the station for further testing. This is either performed using a more accurate breathalyzer, or a blood test. In general, suspects can choose which test they want (blood or breath).
