Habitual Offender:

A habitual offender is defined differently by many states. However, typically a habitual offender is someone who has three DWI convictions over a specific amount of time. You’ll need to check with your state or local DWI attorneys to learn the exact habitual offender laws where you live.

Some states have what are referred to as implied consent laws, meaning that if you hold a drivers license in one of these states you are agreeing that if you are ever stopped for DWI that you automatically consent to testing and the officer does not need to ask your permission. The state of Nevada allows for refusals of testing while still in the field.
