Refusal leads to administrative license suspension/revocation through DMV processes distinct from the criminal case. Breath refusal may carry criminal penalties consistent with Birchfield; compelled blood draws for criminal refusal purposes generally need a warrant. That is what separates New Hampshire refusing a breathalyzer from a generic national summary. Read N.H. Rev. Stat. Ann. § 265-A:4 before the background sections below. New Hampshire's implied-consent statute requires submission to chemical testing upon lawful DUI arrest; refusal has administrative license consequences.
License suspension and administrative hearings
Refusal leads to administrative license suspension/revocation through DMV processes distinct from the criminal case.
The DMV / administrative track often runs separately from the criminal DUI case. Missing the short window to request an administrative hearing can lock in a suspension even if the criminal charge is later reduced or dismissed. Always calendar the administrative deadline the same day as the arrest.
Criminal consequences of refusal
Breath refusal may carry criminal penalties consistent with Birchfield; compelled blood draws for criminal refusal purposes generally need a warrant.
Under Birchfield v. North Dakota, the Fourth Amendment allows criminal penalties for refusing a warrantless breath test incident to a lawful DUI arrest, but generally requires a warrant (or a recognized exception) before the State may impose criminal penalties for refusing a blood draw. Missouri v. McNeely rejected a per-se exigency based solely on natural dissipation of alcohol in the blood. New Hampshire statutes and case law implement those federal baselines with local detail.
Can refusal be used as evidence?
BAC results and refusal evidence are routinely used at trial, with foundation and confrontation issues litigated case-by-case.
Prosecutors often argue consciousness of guilt; defense counsel emphasize confusion, inadequate advisories, or medical inability to provide a sample. The precise jury instruction language is state-specific — search New Hampshire opinions for “refusal” and “implied consent.”
A concrete New Hampshire scenario
Here is one way the New Hampshire pieces fit together. Change any fact and the statute may point somewhere else.
A driver is arrested for DUI in New Hampshire and refuses the evidentiary chemical test after the implied-consent advisory.
- Identify the administrative consequence under N.H. Rev. Stat. Ann. § 265-A:4: Refusal leads to administrative license suspension/revocation through DMV processes distinct from the criminal case.
- Separate that track from the criminal case: Breath refusal may carry criminal penalties consistent with Birchfield; compelled blood draws for criminal refusal purposes generally need a warrant.
- Ask whether the refusal can be argued to the jury: BAC results and refusal evidence are routinely used at trial, with foundation and confrontation issues litigated case-by-case.
- If the request is for blood rather than breath, apply the warrant rule: Breath testing is primary for alcohol; blood testing is used for drugs, hospital settings, or when breath is impractical, typically under warrant.
In New Hampshire the refusal question is answered first by N.H. Rev. Stat. Ann. § 265-A:4, then by the administrative deadline and the criminal case.
Breath tests versus blood tests
Breath testing is primary for alcohol; blood testing is used for drugs, hospital settings, or when breath is impractical, typically under warrant.
Practical tip: a driver who refuses breath may still face a warrant-backed blood draw. Refusal does not create a permanent shield against chemical evidence; it mainly adds administrative (and sometimes criminal) consequences on top of the underlying DUI case.
Practical tips
- Ask whether the stop and arrest were lawful — implied consent usually requires a lawful DUI arrest first.
- Diary the administrative hearing deadline immediately.
- Do not confuse portable roadside breath screens with the evidentiary breathalyzer at the station; statutes often treat them differently.
- Research New Hampshire opinions on implied consent, refusal, and license revocation in LawDiver before a contested DMV hearing.

- Criminal exposure: Breath refusal may carry criminal penalties consistent with Birchfield; compelled blood draws for criminal refusal purposes generally need a warrant.
- Evidence: BAC results and refusal evidence are routinely used at trial, with foundation and confrontation issues litigated case-by-case.
- Blood vs. breath: federal Supreme Court doctrine in Birchfield and McNeely still frames warrant rules.
Implied consent in New Hampshire
New Hampshire's implied-consent statute requires submission to chemical testing upon lawful DUI arrest; refusal has administrative license consequences.
Implied consent is not the same as a Miranda warning. Officers typically must advise of the consequences of refusal before requesting a chemical test. Failure to give a required advisory can affect whether the administrative suspension sticks — a frequent issue in New Hampshire appellate opinions.
