Level 2 ADAS Incident Report Data

File Identity

SGO-2021-01_Incident_Reports_ADAS.csv is the NHTSA dataset of Level 2 advanced driver assistance system crash incidents collected under Standing General Order 2021-01, first issued in June 2021 and amended three times through April 2025. The General Order requires manufacturers of Level 2 ADAS systems to report qualifying crashes to NHTSA on a 1-day or 5-day timeline depending on crash severity.^1,4,5

Level 2 ADAS refers to SAE Level 2 automation: systems that simultaneously control both lateral motion (steering) and longitudinal motion (acceleration and braking), but require the human driver to remain engaged and supervise the system at all times. Common systems include Tesla Autopilot, GM Super Cruise, Ford BlueCruise, and Volvo Pilot Assist. These systems differ from Automated Driving Systems (ADS), which are Level 3 and above and do not require continuous human supervision.^1,5

What Triggers a Report

A crash involving a Level 2 ADAS-equipped vehicle is reportable only when two conditions are met: (1) the ADAS was in use at any point within 30 seconds of the crash, and (2) the crash crossed at least one of the thresholds below. Crashes below these thresholds are not in this dataset.^1,5

Manufacturers subject to the General Order must also file a monthly “No New or Updated Incident Report” submission when they have no reportable crashes in a given month.^1,5

Key Data Fields

The CSV contains 152 columns. The fields below are the most consequential for crash analysis. The full data element definitions, including coded values for each categorical field, are in the official NHTSA data dictionary.⁴

Two-File Structure

NHTSA split the ADAS dataset into a current file and an archive file when the third amendment took effect on June 16, 2025. Researchers who need the complete series from 2021 through the present must download both files and combine them.^1,2,3

How Daily Driver Advocate Uses It

This dataset is a primary federal source for ADAS safety research. Daily Driver Advocate uses it to provide context on the crash record of Level 2 assistance systems alongside NHTSA FARS fatal-crash data.^1,2,3

Common Research Uses

This file is most useful when a researcher needs the federal primary-source record for Level 2 ADAS crash incidents rather than a secondary summary or news report.^1,2,3,4

Important Limitations

• The dataset covers only crashes where Level 2 ADAS was engaged during the 30 seconds before the crash AND the crash met one of the reporting thresholds (fatality, hospitalization, VRU, tow-away, or airbag deployment). Crashes below those thresholds are not included.
• ADAS engagement status is self-reported by the manufacturer. The "Alleged Engaged" category indicates the manufacturer could not independently confirm the system was active.
• Personally identifiable information and confidential business information are redacted from the published CSV. Some city and location fields may be blank.
• The dataset is split into two files. The current file covers June 16, 2025 onward; the archive file covers July 2021 through June 15, 2025. Researchers who need the full historical series must download both files.
• This dataset is not directly comparable to NHTSA FARS. FARS is a census of all fatal crashes on public roads; the SGO ADAS file covers a specific technology-triggered subset of crashes across all injury levels.
• The SGO applies only to manufacturers with 500 or more ADAS-equipped vehicles on U.S. roads in the previous calendar year. Smaller or newer entrants may not yet be required to report.

Suggested Citation

For the raw dataset, cite NHTSA as the issuing agency and include the Standing General Order number. For the full historical series, cite both the current and archive files.
