If you get pulled over and appear impaired and then fail a field sobriety test, you can, and should be arrested. Only after "legal" arrest can they test you to determine if their suspicion is right. Obviously you'd pass a breathalyzer. If you took a blood or urine test which showed extreme levels of pseudoephedrine (amphetamine), you'd be in trouble.
But, if you take this dose daily, you would never have the elevated levels to say you were impaired. This isn't about taking cold or sinus medication as directed, it's about people buying OTC substances, taking them in excess, be it purposely or accidentally, and driving impaired.
