+# Lateral Maneuvers Testing Tool
+
+> [!WARNING]
+> Use caution when using this tool.
+
+Test your vehicle's lateral control tuning with this tool. The tool will test the vehicle's ability to follow a few lateral maneuvers and includes a tool to generate a report from the route.
+
+## Instructions
+
+1. Check out a development branch such as `master` on your comma device.
+2. The full maneuver suite runs at 20 and 30 mph.
+3. Enable "Lateral Maneuver Mode" in Settings > Developer on the device while offroad. Alternatively, set the parameter manually:
+
+   ```sh
+   echo -n 1 > /data/params/d/LateralManeuverMode
+   ```
+
+4. Turn your vehicle back on. You will see "Lateral Maneuver Mode".
+
+5. Ensure the area ahead is clear, as openpilot will command lateral acceleration steps in this mode. Once you are ready, set ACC manually to the target speed shown on screen and let openpilot stabilize lateral. After 1 seconds of steady straight driving, the maneuver will begin automatically. openpilot lateral control stays engaged between maneuvers normally while waiting for the next maneuver's readiness conditions. The maneuver will be aborted and repeated if speed is out of range, steering is touched or openpilot disengages.
+
+6. When the testing is complete, you'll see an alert that says "Maneuvers Finished." Complete the route by pulling over and turning off the vehicle.
+
+7. Visit https://connect.comma.ai and locate the route(s). They will stand out with lots of orange intervals in their timeline. Ensure "All logs" show as "uploaded."
+
+   ![image](https://github.com/user-attachments/assets/cfe4c6d9-752f-4b24-b421-4b90a01933dc)
+
+8. Gather the route ID and then run the report generator. The file will be exported to the same directory:
+
+    ```sh
+    $ python openpilot/tools/lateral_maneuvers/generate_report.py 98395b7c5b27882e/000001cc--5a73bde686
+
+    processing report for KIA_EV6
+    plotting maneuver: step right 20mph, runs: 3
+    plotting maneuver: step left 20mph, runs: 3
+    plotting maneuver: sine 0.5Hz 20mph, runs: 3
+    plotting maneuver: step right 30mph, runs: 3
+
+    Opening report: /home/batman/openpilot/tools/lateral_maneuvers/lateral_reports/KIA_EV6_98395b7c5b27882e_000001cc--5a73bde686.html
+    ```
+
+You can reach out on [Discord](https://discord.comma.ai) if you have any questions about these instructions or the tool itself.
