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.
