Ignition Interlock Report
State Ratings & Drunk Driving Attempts Prevented
Introduction An ignition interlock is a device about the size of a smartphone that is wired into the ignition system of a vehicle and requires a breath sample from the driver to measure the driver’s breath alcohol concentration. A driver can be ordered to use one following a drunk driving arrest or conviction, typically for a duration of at least six months. In most states, ignition interlocks are set at .02 BAC, and the vehicle will not start if the driver’s BAC exceeds that limit. This report outlines the effectiveness of ignition interlock laws with three data points: 1. The number of times an ignition interlock has prevented a drunk driver from starting their vehicle per state
Interlocks are more effective than license suspension as the American
Association of Motor Vehicle Administrators
estimates that 75% of people continue to drive on a suspended license.
2. A grade for each state’s ignition interlock law and recommendations for improvement
3. Loopholes that prevent the full benefit of ignition interlock laws
MADD collaborates with partners to evaluate laws and identify areas for improvement in state laws. This report identifies the progress made over nearly two decades of advocating for all-offender ignition interlock laws and informs the work in the year ahead.

MADD’s Support for All-Offender Laws
In 2006:
Today:
MADD began prioritizing the passage of state laws requiring the use of ignition interlocks for all convicted drunk drivers in 2006, because years of data showed that suspending a drunk driving offender’s license was not effective in preventing driving and changing behaviors. At the time, only New Mexico required ignition interlocks for all drunk drivers, starting with the first offense. Four states required the devices for first-time offenders with a BAC of .15 or greater, and another five states required them for repeat offenders. Today, 34 states and Washington, D.C., mandate the use of ignition interlocks after the first offense. MADD, volunteers and partners work together to urge states to enact an all-offender ignition interlock laws, meaning a drunk driver must use an ignition interlock if they choose to drive after a conviction or during a court-ordered or administrative license suspension.
Only 2% of states (including D.C. and Puerto Rico) mandated the use of ignition interlocks after first offense.
65% of states (including D.C. and Puerto Rico) mandate the use of ignition interlocks after first offense.

5.7 Million Drunk Driving Attempts Stopped Since 2006
Research and studies demonstrate ignition interlocks are an effective tool to stop drunk driving, save lives and change behavior. But how many times have these devices stopped someone from driving drunk? MADD set out to answer this question 10 years ago and released the first-ever report detailing the number of times an ignition interlock stopped a convicted drunk driver from driving with a breath alcohol concentration (BAC) of .08 or greater. The findings were shocking: Ignition interlocks had stopped millions of attempts to drive drunk, preventing repeat offenses and potential deaths and injuries.
MADD builds on this data each year, collecting both national and state-specific statistics to help educate state policymakers, elected officials and the public on the lifesaving benefits of strong ignition interlock laws. The data show that ignition interlocks are making a real difference to stop this crime. Since MADD began its focus on all-offender ignition interlock laws in 2006, the devices have stopped nearly 5.7 million attempts to drive drunk with a BAC of .08 or greater, including over 335,000 in 2025 alone.

Breath Alcohol Levels
State laws typically follow standards recommended by the National Highway Traffic Safety Administration to require ignition interlocks to be set at a lower threshold of .02 breath alcohol content (BAC) to prevent any drinking and driving occurrences. Since 2006, interlocks prevented over 44.2 million attempts to drive with a .02 BAC or greater, including 2.6 million in 2025 alone.

Closing Loopholes
Although 34 states and Washington, D.C. have laws that require every drunk driver to use an ignition interlock or not drive at all, there are many loopholes that allow an offender to avoid an ignition interlock requirement.

Top Four Weaknesses in State Laws
33 states plus Puerto Rico make drunk drivers wait a specified period before installing an interlock. MADD believes drunk drivers who did not cause an injury should be eligible to use an interlock upon arrest or administrative or court ordered license revocation. MAKING DRUNK DRIVERS WAIT TO USE AN IGNITION INTERLOCK According to data collected by NHTSA, roughly 1 in 5 suspected impaired drivers refuse a BAC test. 19 states plus Puerto Rico do NOT require these offenders to use an interlock in order to drive during a license suspension. NO INTERLOCK REQUIREMENT FOR REFUSALS
WAITING OUT AN INTERLOCK PERIOD
The biggest loophole is offenders can wait out the suspension period or interlock restriction and choose not to drive. 37 states plus Puerto Rico DON’T require all offenders to use an interlock before obtaining a license.
NO COMPLIANCE-BASED REMOVAL LAW 21 states plus Puerto Rico DON’T require all drunk drivers to prove compliance with the interlock order before obtaining a regular license.

Grading Ignition Interlock Laws
As a whole, the nation scores a 53% for ignition interlock laws. National Average F
MADD graded state ignition interlock laws based on five criteria. The grades are meant to encourage action in legislatures to improve drunk driving laws. MADD thanks prosecutors, law enforcement, highway safety officials and all of those involved with implementing current ignition interlock laws to keep the public safe.

LAW WEIGHTED SCORE
DESCRIPTION OF SCORE
A CDC meta-analysis of interlocks studies found that ensuring all offenders use an interlock to drive during a license revocation or suspension is proven to reduce repeat offenses by 67% compared to license suspension alone. This category of the law is the most important and the most weighted in our grading chart. The biggest loophole that the majority of states have with their interlock law is the ability to wait out the use of an interlock following revocation. The best way to ensure that a drunk driver uses an interlock is to require the person to use the device before ever obtaining a legal unrestricted driver’s license. Studies on interlock found that once the device is removed, the person can relapse and drive drunk again. Compliance-based removal extends a drunk driver’s use of an interlock when there are too many drunk driving attempts or other violations while utilizing the device. States still make drunk drivers wait days or months before having the opportunity to be taught how to drive sober with an interlock. Ensuring these devices are available as soon as legally possible after a drunk driving offense will accelerate the safety benefits of ignition interlock use. According to NHTSA, nearly one in five suspected drunk drivers refuses to submit to a chemical test upon arrest. Ensuring that interlocks are a condition of any driving privileges granted for a refusal helps close loopholes. The majority of states have enacted such laws.

MADD’s Call to Action
Since 2006, MADD helped with the passage of hundreds of laws to improve state ignition interlock laws. However, there is still a lot of work to do. States must close loopholes in ignition interlock laws to maximize the lifesaving benefits of this technology. According to the National Highway Traffic Safety Administration, drunk driving deaths increased 17% from 2019 to 2024. States can take action now to ensure every convicted drunk driver uses this device. MADD calls on state lawmakers to ensure anyone convicted of a drunk driving offense must install an ignition interlock for at least six months before ever obtaining an unrestricted driver’s license. All states must remain vigilant to close any loopholes that allow convicted drunk drivers to avoid an interlock.
Drunk driving deaths increased 17% from 2019 to 2024.
MADD, advocates, and partners push for ignition interlock legislation in New York.
