1. (a) Reporting required under this section shall become operative 120 days after the effective date of these regulations.

2. (b) The manufacturer shall report to the department any automated driving system braking event that produces speed decrease of 3 m/s or more from braking at a deceleration rate that exceeds 5 m/s/s for at least 0.5 seconds during the operation of an autonomous vehicle in autonomous mode on a public road with a posted speed limit of 35 miles per hour or higher. The report shall be submitted using the electronic Braking Event Reporting Template (Rev. 12/2025) provided by the department, which is hereby incorporated by reference. The manufacturer shall submit the report electronically in .csv format via the department's web page or portal. The report shall include the following:

   1. (1) Date (YYYY-MM-DD) and time (in 24-hour format) of the braking event.
   2. (2) 17-character vehicle identification number of autonomous test vehicle.
   3. (3) Latitude and longitude coordinates, with four decimal places of precision, where braking event was initiated by the autonomous test vehicle.
   4. (4) The type of object(s) that the automated driving system perceived to trigger the braking action (e.g., another vehicle, vulnerable road user, object on the road, roadside object, or no recognized object).
   5. (5) The range, in meters, and the closing rate (i.e., speed difference), in meters per second, between the autonomous vehicle and the object at the time that triggered the braking event.
   6. (6) Magnitude of speed reduction produced by the braking event in m/s.
   7. (7) Highest braking rate, averaged over 0.5 second interval, during the braking event.

3. (c) The first report shall cover the period from 60 days after issuance of the Drivered Testing Permit, form OL 315 (Rev. 9/2024), which is hereby incorporated by reference, or a Driverless Testing Permit, form OL 315A (Rev. 10/2023), which is hereby incorporated by reference. A manufacturer that holds both a Drivered Testing Permit, form OL 315 (Rev. 9/2024), which is hereby incorporated by reference, and a Driverless Testing Permit, form OL 315A (Rev. 10/2023), which is hereby incorporated by reference, may submit a single report that makes clear which braking events occurred under each type of testing permit.

   1. (1) After the first report, subsequent monthly reports shall be submitted by the thirtieth day of the following month.
4. (d) If no applicable braking event occurred during the reporting period, the manufacturer shall report such to the department.
