A person whose driver’s license has been suspended or revoked following an arrest for DUI/DWI generally may apply to have their license reinstated at the end of the suspension or revocation period by paying a reissue or reinstatement fee and providing proof of financial responsibility (insurance)—but only after completing any court-ordered sentence, including (1) jail or prison time, (2) work furlough or work release, (3) probation, (4) DUI traffic school, alcohol rehabilitation, treatment, or intervention programs, and (5) payment of fines and court costs.

A driver’s license that has been suspended or revoked is not automatically reinstated when the suspension or revocation period ends, and the driver must complete the reinstatement process to drive legally.

Laws regarding the reinstatement of a driver's license after suspension or revocation for a DUI/DWI arrest vary from state to state and are generally located in a state's statutes—often in the vehicle code, transportation code, or vehicle and traffic code.

In New Hampshire, after a DUI/DWI arrest resulting in a driver's license suspension or revocation, an individual must wait until the end of the suspension or revocation period before applying for reinstatement. To legally drive again, the individual must complete all court-ordered sentences, which may include jail time, probation, participation in alcohol education or treatment programs, and payment of all fines and court costs. Additionally, they must pay a reinstatement fee and provide proof of financial responsibility, typically in the form of auto insurance. The process of reinstatement is not automatic; the driver must proactively complete the necessary steps and submit the required documentation to the New Hampshire Department of Safety, Division of Motor Vehicles (DMV). The specific requirements and procedures are outlined in New Hampshire's statutes, which can be found in the state's motor vehicle laws.
