📅 2026 Update: Recent Developments in Ignition Interlock Devices

Since the original article was published, significant changes have occurred regarding ignition interlock devices. New legislation and incidents have impacted how these devices are used and regulated in the United States. The earlier article continues further down the page.

🚗 New Legislative Proposal in North Carolina

On May 13, 2026, North Carolina lawmakers introduced a bill that would require ignition interlock devices for all drivers convicted of driving while impaired. This proposal expands the previous law that only mandated these devices for repeat and severe offenders. If passed, this could lead to a significant increase in the number of drivers subject to interlock requirements.

🔒 Cybersecurity Issues Affecting Service

In March 2026, Intoxalock, a major provider of ignition interlock devices, experienced a cyberattack. This incident disrupted services for hundreds of customers and affected device calibrations across 46 states. The attack left thousands of drivers unable to start their vehicles due to malfunctioning devices, raising concerns about the reliability of these systems.

💰 Current Costs for Ignition Interlock Devices

As of 2026, the typical installation fee for ignition interlock devices ranges from $70 to $150. Monthly monitoring fees remain between $50 and $120, which translates to about $2 to $4 per day. Calibration fees, required every 30 to 90 days, cost between $20 and $60 per visit.

The total annual costs can range from $1,000 to $2,400, not including installation and calibration fees.

📅 Important Deadlines in Arizona

In Arizona, drivers must install an ignition interlock device within 30 days of conviction. Failure to do so could result in immediate suspension of driving privileges and possible extensions of the interlock requirement. Timely compliance is crucial to maintain driving rights.

An ignition interlock system aims to prevent drivers from driving drunk.  The installation of ignition interlocks is often mandated in DUI offenders.  In many cases, those convicted of a DUI will continue to drive drunk even after the penalties and fines associated with a first offense.  On average, a first time drunk driving offender has driven drunk 87 times prior to being arrested.  Additionally, 50 to 75 percent of drunk drivers whose licenses are suspended continue to drive. 

These statistics prove that when a person is arrested for drunk driving it is not usually the first time and will probably not be the last time they have driven drunk.  They also indicate that drivers who have been convicted of a DUI are not likely to follow the rules of their probation and may be driving drunk.  In many cases, those with a DUI conviction may choose to drive drunk or on a suspended license because there is a chance they won't get caught.  An ignition interlock system makes the chances of driving drunk without being caught much less.

Ignition Interlock Purpose Explained

The importance of preventing drunk driving and effectively discouraging those who have driven drunk from doing so again lies in the number of deaths and injuries caused by drunk driving every year.  Over 11,000 people are killed very year due to drunk driving.  These accidents are preventable if measures to reduce drunk driving, such as the installation of ignition interlocks, are taken.  Preventing those with DUI convictions from getting back on the road can save many lives.  Every time a driver gets on the road and has been drinking, the chances of causing serious harm or even death to him or herself and others is increased.

An ignition interlock will not only prevent a drunk driver from starting a car by requiring a breathalyzer test, an ignition interlock system may also prevent a friend from starting the car for a drunk driver by requiring repeat tests and setting off signals if they are not successfully completed.  Ignition interlocks can keep drunk drivers off the road and teach those who have been convicted of DUIs to not drink drunk again.  

Additionally, ignition interlocks are visible and anyone who gets in the car with a driver will know that he or she has one.  This may allow passengers to make better decisions regarding riding with a driver and it may also further motivate a person to refrain from drinking and driving in the future because of the shame or humiliation caused  by such a device.  Additionally, ignition interlocks cost money to install and lease every month, a further motivator for refraining from drunk driving in the future.

Ignition interlocks can be better solutions to drunk driving than suspending licenses because drivers are still able to use their cars when they are sober to get to work, the grocery store or other places where they have to be.  They prevent convicted DUI offenders of driving drunk without preventing them from maintaining a productive life.  Thousands of lives can be saved by the installation of ignition interlocks on the vehicles of those with DUI convictions.
