Second. If you refuse to provide a test the FAA treats that as a positive test and a positive marker for abuse. You will lose the medical and have to do the full deal as a dependent abuser of alcohol.
If you refuse the test
which follows an arrest, the FAA treats it as a positive test. Not the Preliminary Breath Test (PBT).
There is already a legal presumption that if you take the breath or chemical test within 45 minutes of the stop, the result is presumed to be your BAC at the time of operating. If you refuse a PBT, then get arrested and take the chemical test at the station, what would your refusal to take the PBT matter?
Remember, you only have to report "arrests". Not traffic stops that result in no arrest nor citation. If you refuse to participate in FSTs and/or a PBT, the cop knows they have no probable cause to arrest, and let you go without arrest, you wouldn't have to report this.
When you are asked to voluntarily take the FSTs/PBT, you are being detained, but you are not under arrest. You can refuse this all you want without repercussions. The FAA CANNOT use your refusal of FSTs/PBT against you.
While I am a huge proponent of never ever talking to the police, being stopped under suspicion of impaired driving is unique in that there is implied consent if you decide to operate a vehicle.
There is NOT implied consent to participate in voluntary FSTs/PBT. Never was, never has been.
Essentially all a cop is required to do in order to compel submission to a sobriety test is articulate reasonable suspicion of impairment.
Wrong. They need reasonable articulable suspicion to initiate a traffic stop, and they can request you take FSTs, followed by a PBT, as part of this stop. But these tests are voluntary. Refusing FSTs/PBT cannot be used against you, not even by the FAA. Only if he finds probable cause to arrest (refusing to participate in FSTs/PBT does not provide probable cause by itself), arrests you, gives you the opportunity to take a chemical test via either a
calibrated breath machine (field breathalyzers are not , blood, or urine, and you refuse, can this be used against you. But even then he cannot "compel" you to take it because you can still refuse it. It's just going to count against you if you do.
There is legal precedent established by a kid who was pulled over for driving with his high beams on. Cop claimed to smell an overwhelming amount of alcohol. The suspect wanted to do a breathalyzer, decided to humor the cop with his FSTs/PBT while repeatedly saying to the cop "Let's do the breathalyzer already, let's get this over with", finally does the breathalyzer and blows a 0.00. Then the cop decides "Oh...you must have smoked weed", to which the kid explained he was on the college football team and they get tested every Friday. The cop says "Well today's Saturday", to which the kid replied "Weed is in your system for at least 30 days. I'd be off the team come next Friday." Cop arrests him anyway. He then sees a drug/alcohol specialist, who found that he was not under the influence nor impaired in any way, and sent him home. Kid has a huge lawsuit on the cop, who claimed qualified immunity. The circuit court found that because the cop had no probable cause to arrest, he does not get qualified immunity.
Even in matters of DUI, cops have no more rights on a DUI stop than in any other crime. There are no "exceptions" to DUI. They act like there are, but there are not. They just get away with a lot because people are afraid to fight it. Watch some sober DUI stops on YouTube. You'll figure out just what the cops are and are not allowed to do.
