1. A method of operating a vehicle subject to a travel restriction, comprising:
determining when the vehicle is traveling in an unloaded state;
determining a speed of the vehicle when the vehicle is traveling in the unloaded state to produce an actual travel empty speed;
comparing the actual travel empty speed with an historical travel empty speed for the vehicle;
determining that the vehicle operation is subject to the travel restriction when the actual travel empty speed is less than a predetermined percentile of the historical travel empty speed;
when the vehicle operation is not subject to the travel restriction:
evaluating the vehicle operation based on at least one established performance parameter for the vehicle under a normal operating condition; and
changing at least one vehicle performance parameter during future vehicle operation based on said evaluating; and
when the vehicle operation is subject to the travel restriction:
continuing to operate the vehicle without performing at least one of said evaluating and changing steps.
