1. A system comprising:
a memory;
a first sensor configured to determine at least one of a distance from a dolly to a forward trailer or an angle from the dolly to the forward trailer;
at least one processor in communication with the memory and the sensor, where the at least one processor is configured to execute instructions stored in the memory and to:
determine that a forward trailer is moving in a reverse direction;
determine a steering angle of a vehicle coupled to the forward trailer based on information received from the vehicle coupled to the forward trailer;
measure a rotation of the forward trailer based on information received from the first sensor; and
apply at least one of braking or wheel speed control to at least one wheel of the dolly connected to the forward trailer based on the measured rotation of the forward trailer and the determined steering angle of the vehicle coupled to the forward trailer.
