Question
For 2025, Formula SAE now requires a Tractive System Status Indicator. The intent is to provide a clear indication of a fault that is visible to the track workers.

We have received several questions about the Tractive System Status Indicator:
Answer
Q: Does the Tractive System Status Indicator need to be two separate red and green lights?
A: Yes, this is the Formula SAE Rule EV.5.11.2 requirement

Q: May we use software to control the Tractive System Status Indicator?
A: Yes. Be aware that any software issues that prevent the Status light from functioning properly could cause a Red Car condition or Void the Inspection Approval.

Q: Our Shutdown Circuit will give a fault indication on the Tractive System Status Indicator when powered on, then we have to hit a reset which will clear the fault indication. Is this allowed, and will it create any issues?
A: We are discussing this situation, and will provide an update to this FAQ.

Q: What if the Tractive System Status Indicator is not functioning properly?
A: Issues that affect the Status light will cause a Red Car condition. If the Status light is not indicating properly, this may Void the Inspection Approval or result in a penalty, subject to official discretion.

Q: Are there any specific visibility requirements for the Tractive System Status Indicator?
A: In addition to EV.5.11.3.b, the Tractive System Status Indicator must be visible from the front of the vehicle. The Tractive System Status Indicator should be visible from angles other than directly ahead of the vehicle. We expect to clarify specific requirements if needed.
