What is implied consent? @Max Rockatansky seems to believe that he must submit to a check on his papers and breathalyzers due to implied consent laws.
Implied consent, first and foremost, is not expressed consent. It is a statement by some municipalities that because you are doing "A" you consent to "B". When you agree to get a state license you also agree to the rules regulating driving in that state.
It also does pesky things like if you loan someone your gun and they kill someone you're liable in civil court, as well, but let's get back to driving.
What implied consent laws can do and what they can't do is defined below:
What they can do
They can require a breathalyzer test if you are perceived to be driving drunk
What they can't do
Make you take the breathalyzer test
What they can do
Suspend your license for refusing to take the breathalyzer test
What they can't do
Continuance of suspension without the consent of the judge
What they can do
Take you to the police station and charge you on suspicion of driving drunk if you refuse to take the test
What they can't do or don't do
Signify that your refusal is due to guilt.
So when in doubt, say "no" and ask for a lawyer. It's better to be thought guilty than proven guilty, so sayeth every attorney everywhere.
