A system and method for controlling a vehicle system may determine one or more of a route parameter of a route on which the vehicle system is moving or a vehicle parameter of the vehicle system. The system and method may also determine whether a ratio of a lateral force exerted by one or more wheels of the vehicle system on the route to a vertical force exerted by the one or more wheels of the vehicle system on the route increases to a value exceeding a designated threshold as a result of the one or more route parameter of vehicle parameter that is determined. The ratio of the lateral force to the vertical force exerted by the one or more wheels of the vehicle system on the route may be reduced to a value less than the designated threshold by changing an operation of the vehicle system.
