An automatic axle lift system including a first sensor circuit configured to detect the presence of a brake signal and a turn signal and, in response, to generate a lift command signal that lifts an axle or a set of axles of a vehicle. The automatic axle lift system also includes a second sensor circuit that detects the lift command signal and, in response, generates a caution light signal. The automatic axle lift system includes a third sensor circuit that detects the lift command signal and, in response, latches the second sensor circuit to maintain the lift command signal.
