Why It Matters
North Carolina lawmakers are advancing legislation that would significantly broaden the state’s drunk driving deterrence framework, requiring ignition interlock devices — commonly known as breathalyzer locks — for every driver convicted of driving while impaired, including first-time offenders. The proposal marks a shift away from license suspension and incarceration as primary enforcement tools toward technology-based behavioral intervention.
What Happened
House Bill 1199, known as the SEATBELT Act, was introduced in the North Carolina House of Representatives with primary sponsorship from Rep. Mike Schietzelt (R-Wake), Rep. Allen Chesser (R-Nash), Rep. Timothy Reeder (R-Pitt), and Rep. Erin Paré (R-Wake). Three Democratic lawmakers have also signed on as co-sponsors, giving the measure initial bipartisan backing.
Under existing North Carolina law, ignition interlock devices are only mandated for repeat DWI offenders and those who registered a high blood alcohol content at the time of arrest. The bill would extend the requirement to all DWI convictions, regardless of prior driving history.
Convicted drivers would be required to equip any vehicle they own or regularly operate with the device for a minimum of one year. Those who comply could also regain limited driving privileges earlier than current law allows.
Schietzelt and fellow sponsors held a press conference Wednesday, May 13, where they were joined by public safety officials, advocates, and individuals personally affected by impaired driving incidents.
By the Numbers
- 3 million+ — attempted drunk-driving starts blocked by ignition interlock devices across the U.S. over a 12-year period, according to data cited by Mothers Against Drunk Driving
- ~70% — reduction in repeat DWI offenses associated with interlock device use, according to the Centers for Disease Control and Prevention
- $3/day — approximate daily cost of operating a breathalyzer lock, as cited by Rep. Schietzelt
- $100–$150 — estimated upfront installation cost per vehicle
- 150% of the federal poverty line — income threshold below which offenders may apply for a fee waiver; recipients of public assistance would also qualify
The Case for the Legislation
Supporters of the bill argue that license suspension has failed as a deterrent because many impaired drivers simply continue driving without a valid license. Schietzelt framed the technology as a more precise response: “We have the technology now to tailor it to the offense, to change the behaviors, and to make North Carolina’s streets safer,” he said at the press conference.
Rep. Reeder, an emergency physician who has treated victims of drunk-driving crashes, said the bill reflects a medical reality he encounters regularly. “We should no longer rely on just a punishment, but use the available tools to prevent someone from getting behind the wheel,” he said.
Stephanie Ronan, a mother of two who appeared at Wednesday’s event, described the lasting consequences of a 2018 collision with an impaired motorist who was driving on a suspended license. She sustained a serious neck injury and brain trauma, ultimately forcing her to leave her career as an optical technician. “No parent should ever have to experience that,” she said.
Speed Monitoring Provision
The bill includes an additional provision requiring drivers convicted of certain speeding offenses to install an “intelligent speed assistance” system — a GPS-based device that monitors and restricts vehicle speed. Schietzelt addressed that element of the legislation at an earlier press conference this month.
Zoom Out
Several other states have adopted all-offender ignition interlock laws in recent years, and national highway safety organizations have increasingly backed the approach as evidence mounts that suspension-only penalties have limited deterrent effect. The CDC’s finding of a roughly 70 percent reduction in repeat offenses has been influential in state-level policy debates across the country.
North Carolina’s bill is part of a broader legislative session that has seen lawmakers weigh technology-driven approaches to public safety and transportation.

What’s Next
House Bill 1199 remains in the early stages of the legislative process. The measure will need to advance through committee review and floor votes in the North Carolina House before any Senate consideration. The bipartisan support among sponsors could aid the bill’s passage, though the timeline for committee action has not been publicly announced.
