When a Ford F-350 pickup slammed into the rear of a stopped Tesla Model 3 on eastbound Loop 202 near Dobson Road in Mesa last Halloween, initial reports described a routine two-vehicle freeway crash. Nearly ten months later, a redacted federal filing has revealed a detail no one disclosed at the time: the Tesla’s driver-assist system was engaged when the car came to a stop in a live traffic lane, and it stayed there until the pickup hit it at 3 a.m.
The crash happened October 31, 2025, on the Red Mountain Freeway, according to 12News, which reported the Tesla sedan was stationary when the F-350 struck it. The Tesla driver died at the scene. At the time, the Arizona Department of Public Safety confirmed only that two vehicles were involved, and neither the make of the car nor the status of any driver-assist technology was mentioned in initial coverage, per the same station’s report.
That changed when Tesla filed a crash report with the National Highway Traffic Safety Administration, as required under Standing General Order 2021-01, a federal rule mandating that automakers disclose any crash where an SAE Level 2 driver-assist system was engaged within 30 seconds of impact and the incident caused a fatality, hospitalization, airbag deployment, or struck a vulnerable road user, according to NHTSA. Electrek, which first connected the redacted filing to the Mesa crash, reported that the report confirmed the 2020 Model 3 was traveling at 0 mph with its automation status verified engaged, and that the Ford F-350 struck it across its entire rear.
What the Redacted Filing Does and Doesn’t Show
Tesla’s submission left major gaps. Under 49 CFR Part 512, automakers may withhold specific fields — including software build versions, whether the road fell within the driver-assist system’s approved operating area, and the crash narrative itself — by filing confidential business information claims, according to NHTSA. Electrek reported that Tesla redacted the software version and crash narrative in this filing, and that such redactions appear on 99.9% of Tesla’s submitted reports…
