📅 2026 Update: Changes in DUI and DWI Laws and Technologies

Since the original article was published, several important changes have occurred in DUI and DWI laws and related technologies. Key updates include new legislative proposals, advancements in ignition interlock devices, and recent cybersecurity incidents impacting drivers. The information in the earlier article continues further down the page.

🚗 New Legislation on Ignition Interlock Devices

On May 13, 2026, North Carolina lawmakers proposed a bill requiring ignition interlock devices for all drivers convicted of driving while impaired. This expands the previous law that applied only to repeat offenders and those with severe cases. If passed, this bill would significantly increase the number of drivers required to use these devices.

🔒 Cybersecurity Issues

In March 2026, Intoxalock, a major ignition interlock device provider, experienced a cyberattack. This incident disrupted services for thousands of drivers across 46 states, affecting their device calibrations and overall functionality. The event raised concerns about the reliability of these devices, especially regarding their operation during critical times.

💵 Costs of Ignition Interlock Devices

The costs associated with ignition interlock devices have remained consistent. Installation fees typically range from $70 to $150, while monthly monitoring fees vary between $50 and $120. Calibration visits, required every 30 to 90 days, cost between $20 and $60.

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

🛠️ Installation and Compliance

In Arizona, individuals must submit an Ignition Interlock Device Application to the Motor Vehicle Division (MVD) to install a device. If they fail to install the device within 30 days of conviction, they may face immediate suspension of driving privileges. Compliance remains a challenge, with only 41% of required drivers in Washington State adhering to the regulations.

📌 Key Points to Remember

  • North Carolina proposed a bill for ignition interlock devices for all DUI offenders.
  • A March 2026 cyberattack on Intoxalock disrupted services significantly.
  • Installation fees for interlock devices start at $70, with monthly fees around $50 to $120.
  • Arizona has strict deadlines for installation after a DUI conviction.
  • Compliance rates for ignition interlock devices are low in some states.

End of October 2026 Update






Ignition Interlock Devices or IID’s have been the topic of widespread discussion and little debate. For the most part the general population approves them and confirms that they assist in preventing drunk drivers from going out on our roadways and putting our lives in danger. A few people however, tend to argue that the device is unsafe to the driver (mainly people who have them court ordered.)



Nobody likes to get in trouble, or be made an example of, so if someone that was convicted of  DUI has to drive around with an electronic device telling them when they can or can’t drive their vehicle it’s going to bring some conflict. The people that end up with the device in their car argue that it is unsafe to their driving, and interferes with safety.



Some have argued in court that the device allowed them to drive drunk (after having someone else provide a breath sample) and that it led them to crash. Others in the same situation stated that the device let them inaccurately start their car and when providing the next sample they lost control and crashed.  The same was` said about people trying to provide samples during the rolling test. Later these people were found to be drunk, and attempted to bypass the system.

Prevalence and Implementation Explained


Every measurement is going to have a window of inaccuracy but because of the chemical fuel cell in this device, it works in providing extremely accurate samples when dealing with alcohol. Just like with every technology though, people will try to blame its possibility of inaccuracy on their attempt to bypass it.



For the most part, this has failed, which has maintained the credibility of the product. IID’s are used widely across the United States and Canada either as an alternative to harsher sentencing, or in addition to it. The device has helped keep an insurmountable amount of car engines off, when those cars otherwise would have been out of the roadways.



If that was the case, who knows what accidents they could’ve caused, what lives they could’ve taken, to think about that makes people more grateful that such a device exists.  The ability for the enforcers to monitor all the data of activity from the device during calibration has proved as an effective tool to keep offender from trying to tamper with, or bypass the device.



By checking statistics on the web sites of the manufacturers of IID’s, one can see the incredible number of people that these devices have kept off the road. IID’s can be seen as an electronic form of law enforcement, for when a police officer isn’t at the right place at the right time. This provides added assistance to them for catching DUI offenders and preventing them from driving any further, in addition to DUI checkpoints. 



IID’s are clearly a huge help to our society, people, courts, law enforcement agencies, and the lives of people. These little devices make a huge impact on how we try to prevent crime from occurring and are successful in doing so.
