State Law: 24/7 Programs
  • Statewide program
  • Pilot program implemented
  • Pilot program authorized
  • No 24/7 legislation

Under the 24/7 program model, repeat DUI offenders are required to maintain sobriety as a condition of remaining in the community and avoiding incarceration. Participants are tested twice-daily for alcohol through scheduled onsite breath tests or with a continuous alcohol monitoring device. If an offender tests positive for alcohol or drugs, they are taken into custody and appear before a judge within 24 hours. The program is designed to hold offenders accountable through swift, certain, and meaningful sanctions with the ultimate goal of long-term behavior change.

As of 2016, three states (MT, ND, and SD) have implemented 24/7 statewide while others have established pilot programs at the county level (AK, FL, NE, and WA). Several states have passed legislation authorizing pilot programs but they have yet to be implemented (ID, WI, and WY).

To learn more about 24/7 programs, refer to our policy position or access a summary of state statutes.

**Drunkenness is not considered a crime in some states; therefore, the figures may vary widely from state to state

Limited, incomplete, or no data were reported by the District of Columbia, Florida, Illinois, and New York in the 2016 Uniform Crime Report. Data should be used with caution and should not be compared to other states or previous year data.

Note: Because the number of agencies submitting arrest data varies from year to year, users are cautioned about making direct comparisons between 2016 arrest totals and those published in previous years’ editions of Crime in the United States. Further, arrest figures may vary widely from state to state because some Part II crimes of the Uniform Crime Report are not considered crimes in some states.
