Impaired driving in North Carolina, by the numbers

Six decades of crash data, four decades of alcohol-impaired fatality estimates, and a decade of court and sentencing records, pulled from NCDOT, NHTSA, the NC Administrative Office of the Courts, the Sentencing and Policy Advisory Commission and NC DHHS. Every chart cites its source. Hover any chart for exact figures, or open the data tables.

Sixty-five years of road deaths

Deaths on North Carolina roads, 1960–2024

NCDOT has published statewide crash totals every year since 1960. The fatality rate per 100 million vehicle miles fell by roughly three-quarters as cars, roads, seat-belt laws and impaired-driving enforcement changed, even though the number of deaths has climbed back above 1,600 a year as North Carolina grew.

Source: NCDMV/NCDOT, North Carolina 2024 Traffic Crash Facts, annual totals table 1960–2024. NCDOT counts follow the state crash-report definition and can differ from NHTSA FARS (2024: NCDOT 1,732 vs. FARS 1,619). Reporting thresholds changed in 1971 and 1983.

Alcohol-impaired fatalities

How many deaths involve an impaired driver?

Deaths in crashes with a driver at BAC .08+

1982–2003: NHTSA “0.08+” fatalities under the older definition (any driver or non-occupant). 2003–2024: NHTSA “alcohol-impaired” fatalities (driver BAC .08+), latest revised value per year. The two definitions overlap in 2003 and are not perfectly comparable.

Share of all traffic deaths

Share computed from NHTSA alcohol-impaired and total fatality figures (2003–2024) and NHTSA’s printed .08+ percentages (1982–2002). Because many drivers are never tested, NHTSA imputes BAC values; see the BAC-testing caveat below.

How impaired? Driver BAC in fatal crashes

NHTSA: deaths in crashes where the highest driver BAC was .01–.07 versus .15 or higher (2006–2024).

Holidays: alcohol-related deaths

NCDOT Crash Facts holiday tables, persons killed in alcohol-related crashes during each holiday reporting period, 2020–2024.

Police-reported alcohol crashes

Crashes, injuries and deaths where alcohol was reported

NCDOT counts crashes where the officer’s DMV-349 report indicated alcohol involvement, 2007–2024. This is a different measure from NHTSA’s BAC-based estimate.

In the courtroom

What happens to DWI charges in North Carolina courts?

The Administrative Office of the Courts tracked every implied-consent charge filed and disposed in district and superior court. In FY2016–17, about 56.3% of disposed impaired-driving charges ended in a DWI conviction and about 21.8% were voluntarily dismissed by the prosecutor. These are charges, not people, and one arrest can produce more than one charge.

Charges filed and disposed, FY2009–FY2017

NC AOC, “Analysis of Impaired Driving Charges and Implied Consent,” FY2008–09 through FY2016–17. Disposed can exceed filed when older cases are cleared.

How FY2016–17 dispositions ended

Same AOC report. “Dismissed by prosecutor” includes voluntary dismissals; “with leave” cases can be reinstated.

Sentencing

DWI sentencing levels, FY2015–FY2025

North Carolina sentences DWI on six levels under G.S. 20-179: Aggravated Level One (the most serious) through Level Five. Most convictions land at Level Five, the lightest. Read how the six levels work.

Convictions by level

FY2024–25 mix

Type of sentence

Active (jail), supervised probation, unsupervised probation.

BAC of .15 or more at conviction

Share of convictions with a recorded BAC of .15+ (NCSPAC). A .15+ result also triggers ignition-interlock requirements on license restoration under G.S. 20-17.8. See the NC interlock map.

Source: NC Sentencing and Policy Advisory Commission, Driving While Impaired Convictions Statistical Report (annual), FY2015–FY2025. Counts exclude habitual DWI felonies. FY2020–21 reflects COVID-19 court closures; FY2023–25 coincide with the eCourts rollout.

Data tables & downloads

Every number behind the charts

Open a table to see the yearly figures, or download any series as a CSV file for your own analysis. Please cite the original agency source.

Read these numbers carefully. Agencies count different things: NCDOT counts police-reported alcohol involvement; NHTSA estimates driver BAC (and imputes it when tests are missing, which in North Carolina has become common: the share of drivers in fatal crashes with a known BAC result fell from roughly 47% to 21% in recent years); AOC counts charges; NCSPAC counts convictions sentenced under G.S. 20-179; FBI arrest counts cover only reporting agencies. Arrest data are omitted from the charts for that reason.
