Three Separate Proceedings
An arrest for impaired driving starts more than a criminal case. There is also an administrative proceeding about your driving licence, run by the motor vehicle agency, and potential civil liability if anyone was injured.
They operate independently. Winning the criminal case does not automatically restore a licence, and the administrative process typically moves far faster than the criminal one.
The licence deadline is measured in days
Most states require a request for an administrative hearing within a very short window after arrest, often 7 to 15 days. Missing it usually means automatic suspension regardless of what happens in the criminal case. It is the most commonly missed deadline in this area.
Implied Consent and Testing
Every state operates implied consent, under which holding a licence constitutes consent to chemical testing when lawfully arrested for impaired driving. Refusal carries its own administrative penalty, frequently a longer suspension than a failed test.
Breath testing depends on device calibration, maintenance records and operator certification, which are standard subjects of challenge. Blood testing generally requires a warrant absent an exception, following constitutional decisions on the point.
Field sobriety tests are standardised, and deviation from the prescribed administration is a common basis for challenging the conclusions drawn from them.
Civil Exposure
Where an impaired driver injures someone, civil liability follows independently of the criminal outcome. The civil standard of proof is lower, so liability can attach even after an acquittal.
Dram shop statutes in many states extend liability to establishments that served a visibly intoxicated person or a minor, and social host liability applies in some states to private gatherings.
A criminal acquittal does not prevent a civil claim
The civil case requires only a preponderance of the evidence rather than proof beyond a reasonable doubt. A driver acquitted of impaired driving can still be found liable for injuries caused, and insurance coverage may be affected separately.
