Missouri is about to make some of the most significant changes to its DWI laws in years. House Bill 1740 has cleared the state legislature and now sits with the governor. And if signed, the details are worth knowing for anyone who drives in Missouri.
House Bill 1740 is a comprehensive public safety measure that makes significant changes to Missouri’s vehicular laws. Driven by high-profile traffic fatalities, state lawmakers designed this legislation to target repeat offenders, reduce procedural leniency, and establish strict mandatory prison terms. For anyone driving in Missouri, understanding how this pending legislation restructures felony classifications is essential.
Upgrading felonies: new classification structure
The core of HB 1740 modifies statutory definitions under Chapter 577 of the Missouri Revised Statutes, systematically raising the severity of charges for individuals involved in alcohol-related traffic accidents:
- Physical injury penalties: Causing physical injury through criminal negligence while driving intoxicated rises from a Class E to a Class D felony. Causing serious physical injury scales up from a Class D to a Class C felony.
- Vehicular fatalities: A standard DWI causing death scales up to a Class B felony. Incidents involving a Blood Alcohol Content (BAC) of 0.15 percent or higher, or the death of multiple people, escalate further to a Class A felony.
These upgraded classifications raise the baseline prison terms for individuals involved in intoxicated driving accidents across the board.
Restricting leniency and enhancing oversight
Missouri law already prohibits a Suspended Imposition of Sentence (SIS) for repeat or habitual DWI offenders. HB 1740 tightens restrictions further. If a first-time offender receives an SIS, they must now serve a mandatory probation term of at least two years.
The bill also adds significant post-release requirements:
- Mandatory minimums: An offender convicted of a Class B felony DWI causing death cannot seek parole or probation until serving a mandatory minimum of five years. For a Class A felony, that minimum rises to ten years.
- Continuous alcohol monitoring: For repeat offenders who do qualify for supervised release, courts can require continuous alcohol monitoring (CAM) as a self-funded condition of probation.
Once the governor acts on HB 1740 (whether by signing it, vetoing it, or allowing it to become law without his signature) these changes will permanently alter how DWI cases are handled in municipal and circuit courts across Missouri.
