How New Hampshire treats DUI
New Hampshire defines DUI at a BAC of 0.08% or higher and allows judges discretion on sentencing for first offenders, with jail time optional rather than mandatory. License suspension occurs for a minimum of nine months for a first offense. A second offense within ten years carries mandatory jail time and longer suspension periods. New Hampshire also recognizes an "aggravated DUI" for BAC of 0.16% or higher or refusal to submit to testing, which carries enhanced penalties.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
