What a McKinney DWI can cost you
Texas penalties don't vary by city — a first-offense DWI anywhere in the state is a Class B misdemeanor carrying 72 hours to 180 days in jail, up to a $2,000 court fine, a separate $3,000 state fine, and up to a year of license suspension. Repeat offenses, a BAC of 0.15+, or a child passenger can escalate to felony charges. See the full 2026 penalty chart.
