Embodiments generally relate to a trailer safety system for monitoring a vehicle and at least one trailer. The system comprises at least one sensor positioned on a turntable of the vehicle, the sensor being configured to detect the presence of a portion of a first trailer in proximity to the turntable; a first connection component configured to couple to the circuitry of the first trailer and allow control of at least one component of the first trailer; and a control unit. The control unit is configured to receive output signals from the at least one sensor and the first connection component; determine, from the received signals, whether the first trailer has been correctly coupled to the turntable; and generate an alert when it is determined that correct coupling has not occurred.
