Driving change starts here.

Ignition interlock devices

We are the voice of the ignition interlock industry, combining expertise, data, and experience to drive change. By educating people on the value and need for interlock systems with the latest credible and factual information, good public policy can be put into place—which ultimately saves lives.

The effective solution for keeping impaired drivers off the road.

Every hour a person is killed by a drunk driver. Many more suffer life-altering injuries. Alcohol-related crashes also impact our pocketbooks—with economic losses exceeding $44 billion each year. Thankfully, there is effective technology to prevent it. Ignition interlock systems are the only proven solution to stop drunk drivers from starting their vehicle.

How Ignition Interlock devices work

Preventative. Rehabilitative. Cost-effective.

A breathalyzer, about the size of a cell phone, is installed in a vehicle to prevent it from starting if the driver’s Breath Alcohol Concentration (BrAC) exceeds the state’s interlock limit.

These systems increase public safety while still caring for the dignity of the offender.

Preventative. Unlike license suspension or standalone breath analyzers, ignition interlocks prevent alcohol-impaired drivers from starting their vehicle.

Rehabilitative. Offenders get to maintain their driving privileges and responsibilities with minimal intrusion.

Cost-effective. A more economical solution on a daily basis, averaging $3/day.

What an effective ignition interlock law looks like.

Each state administers its interlock program differently. By providing the most timely technical information and research we guide and support policymakers about legislation, implementation, and compliance best practices that drive informed decisions.

Data proves ignition interlocks prevent drunk driving incidents and save lives.
