New Hampshire DUI Laws
In New Hampshire as in other states, it is illegal to drive under the influence of alcohol or drugs. The offense is called driving while intoxicated, or DWI. Under New Hampshire DWI law, it is a per se violation to have a blood or breath alcohol content (BAC) level of .08 percent or higher (less for commercial and underage drivers). Even if your BAC is under the legal limit, the prosecution can build a DWI case based on the arresting officer's observations (e.g., bloodshot eyes, slurred speech or irregular driving patterns) and other evidence of impairment. An experienced New Hampshire DUI lawyer is best qualified to challenge the credibility of the evidence to make certain you have the best possible outcome for your case.
New Hampshire has an Implied Consent law which means that any person driving in the state automatically consents to chemical testing if he/she is properly suspected of driving while impaired. If police have probable cause to suspect DWI and you fail or refuse to submit to a test to determine your BAC, the New Hampshire Department of Safety will suspend your license for at least six months. You have only 30 days to appeal the civil license suspension, and the state does not issue restricted licenses or work permits to DUI offenders. If you are arrested for DWI in New Hampshire, it is wise to call an attorney right away before you lose your driving privileges.
New Hampshire has very tough DWI laws. If you are convicted, penalties will vary depending on the charges, your level of intoxication and the number of prior offenses. Your sentence may include fines, license suspension, counseling and treatment, participation in the Multiple DWI Offender program, a mandatory ignition interlock device and incarceration. You may need to complete an Impaired Driver Prevention Program and obtain SR-22 proof of insurance before you can have your license reinstated. With the consequences so severe, it is highly recommended that you consult an experienced New Hampshire DWI attorney today.
