Introduction
DUI legal costs in Missouri vary depending on whether the charge is a first-time offense or a repeat or aggravated violation, as well as how the case is handled procedurally. Total expenses are influenced by attorney fees, criminal fines, court assessments, and whether the matter is resolved early or proceeds through contested hearings or trial.
A major cost driver in Missouri is chemical test refusal and administrative license actions, which can trigger separate proceedings and additional penalties. Even for first-time offenses, mandatory programs and license consequences can significantly increase overall DUI-related costs.
