Is it illegal to refuse a breathalyzer test?
Legal to refuse, but carries immediate and severe administrative penalties.
Refusing a breathalyzer test is generally legal in the sense that you cannot be physically forced to comply, but it triggers automatic penalties under 'implied consent' laws. By operating a vehicle, you have already consented to chemical testing in exchange for the privilege of a driver's license. Refusal typically results in an immediate license suspension that is much harder to contest than a standard DUI charge. In many states, prosecutors can also use your refusal as evidence of guilt in court.
