Introduction
DUI legal costs in New Mexico depend on whether the charge is a first or repeat offense, whether aggravating factors are present, and whether the case resolves early or proceeds to trial. Even first-time DUI cases often involve attorney fees, court fines, probation costs, ignition interlock requirements, and mandatory alcohol screening or treatment programs, all of which contribute to higher total expenses.
A New Mexico–specific cost driver is mandatory programs and statutory escalation. State law requires ignition interlock installation, alcohol evaluation, and treatment in nearly all DUI cases, and penalties increase aggressively with repeat offenses, driving up both legal and long-term compliance costs.
