And just an FYI, you DO NOT ever have to do a field sobriety test. Never. There is NO good reason to do a field sobriety test whether you're sober or drunk. It can only hurt you.
You also never need to do the roadside breathalyzer. Never. If you are arrested you have to do the official breathalyzer on the calibrated machine at the police station. That's it.
If a police officer asks you to do field sobriety test or roadside breathalyzer they have already made up their mind about your intoxication. What they need now is some reasonable justification to arrest you. That is 100% the only reason they are requesting field sobriety tests and roadside breathalyzer. If they ask for those things nothing good can come from volunteering to provide them with evidence against you.
