- **Occurred:** 2022-04-06
- **Kind:** `collision`
- **Status (derived):** active
- **Model:** [TuSimple Autonomous Truck](/models/tusimple-truck.md) (id: `be575926-7db0-4360-867d-e97689b40126`)

On Apr 6 2022 a TuSimple autonomous truck on I-10 near Tucson abruptly swerved left into the center concrete barrier. A test driver re-engaged autonomy before the system was primed, and the truck executed a stale ~2.5-minute-old steering command that should have been flushed; HMI design + command-stale handling were both implicated. No injuries. Fleet grounded, independent investigation, HMI overhaul deployed. The canonical autonomous-trucking crash.
