Opinion

JUSTICE TIMPONE delivered the opinion of the Court.

**486The case before us concerns New Jersey law enforcement's use of the Alcotest 7110 MKIII-C (Alcotest) to obtain breath samples from drivers suspected of driving under the influence of alcohol. The Alcotest machine analyzes breath samples, producing *89blood alcohol concentration readings used to determine whether a driver's blood alcohol content is above the legal limit. In 2008, we found Alcotest results admissible in drunk-driving cases to establish a defendant's guilt or innocence for drunk driving. State v. Chun, 194 N.J. 54, 65, 943 A.2d 114 (2008). We also required that the devices be recalibrated semi-annually to help ensure accurate measurements. Id. at 153, 943 A.2d 114.

Confidence in the reliability of instruments of technology used as evidence is of paramount importance. Unfortunately, alleged human failings have cast doubt on the calibration process. Marc W. Dennis, a coordinator in the New Jersey State Police's Alcohol Drug Testing Unit, was tasked with performing the semi-annual calibrations on Alcotest instruments used in Middlesex, Monmouth, Ocean, Somerset, and Union Counties. He is charged with neglecting to take required measurements and having falsely certified that he followed the calibration procedures. Dennis was indicted in 2016 for failing to use a thermometer that produces temperature measurements traceable to the standards set by the National Institute of Standards and Technology (NIST) to measure the temperature of simulator solutions used to calibrate Alcotest devices. When Dennis was criminally charged, the Attorney General's Office notified the Administrative Office of the **487Courts that evidential breath samples from 20,667 people were procured using Alcotest machines calibrated by Dennis.

Defendant Eileen Cassidy, now deceased, pleaded guilty in municipal court to driving under the influence based solely on Alcotest results showing her blood alcohol level had exceeded the legal limit. Upon learning that the results of her test were among those called into question by Dennis's alleged falsifications, she moved to withdraw her guilty plea. The Attorney General moved for direct certification. We granted the motion because the central issue of this case is typical to the large number of defendants affected by Dennis's alleged misconduct. We remanded the case to retired Appellate Division Presiding Judge Joseph F. Lisa as Special Master to determine whether "the failure to test the simulator solutions with the NIST -traceable digital thermometer before calibrating an Alcotest machine [would] undermine or call into question the scientific reliability of breath tests subsequently performed on the Alcotest machine." 230 N.J. 232, 232-33, 166 A.3d 238 (2017).

On May 4, 2018, after an extensive evidentiary hearing, the Special Master issued a 198-page report in which he concluded that failure to use a thermometer that produces NIST-traceable temperature readings in the calibration process undermines the reliability of the Alcotest. We now adopt the Special Master's findings because they are supported by substantial credible evidence in the record, see Chun, 194 N.J. at 93, 943 A.2d 114, and we append his report to this opinion.

I.

We briefly highlight the following facts from the record and commend a review of the Special Master's comprehensive report for the finer details. We rely heavily on the Special Master's report.

In 2000, the State began using the Alcotest, a product of Draeger Safety Diagnostics Inc. (Draeger), to conduct breath tests. In 2004, Dr. Thomas A. Brettell developed the current **488calibration protocol while he was director of the State's Office of Forensic Sciences (OFS), and we deemed the Alcotest sufficiently reliable as calibrated pursuant to Dr. Brettell's protocol. Chun, 194 N.J. at 148, 943 A.2d 114. As this Court ordered in Chun, *90N.J.A.C. 13:51-4.3(a) requires the semi-annual calibration of approved instruments used to test the alcohol content of breath samples. Id. at 153, 943 A.2d 114. The regulation, however, does not specify a calibration procedure.

During the calibration process, simulator solutions containing varying concentrations of ethanol are used to calibrate the Alcotest and confirm the accuracy of its blood alcohol content readings. The simulator solutions are poured into calibration units, which are glass containers that house a heating component. The calibration units heat the solutions to about 34 degrees Celsius, the generally accepted temperature for human breath, creating a vapor. The vapor is a proxy for human breath. It is essential that the temperature of the solution be accurate in order for the Alcotest's blood alcohol content readings to be correct. The Alcotest's calibration procedure requires the test coordinator to insert a thermometer that produces NIST-traceable temperature measurements into the simulator solution used to calibrate the Alcotest and confirm that the calibration unit heated the solution to a temperature within 0.2 degrees of 34 degrees Celsius. The NIST is the federal agency responsible for maintaining and promoting consistent units of measurement. When a thermometer's temperature measurements are "traceable" to the standard measurements of the NIST, those measurements are generally accepted as accurate by the scientific community.
