This is not a mandatory field, but by defining a Driver's Rest Break and by having the Viamente Route Planner help you plan it, you can make sure the break will not have too severe an impact on the level of your service.
Break For: this field allows you to define the length of a Driver's break (for example for lunch).
Starting between: if the Driver has a break, these two fields define the Time Window within which you would like the Driver to start his/her break. This way, the starting time of the break will be an output of the optimization process, with the Route Planner suggesting the best moment (within limits of a User-set Time Window) for taking the break, thus minimizing its impact on the efficiency of the Route Plan.
Please note that like all other Driver Settings, Driver's Rest Break can be assigned/modified from under the tab My Fleet or from under the tab Route Plans (by clicking on the Driver's name in the lower part of the screen).
Remember that if you change a Driver’s settings from the tab My Fleet, the new settings will be applied to all future Route Plans whenever this Driver is utilized. If you only need to modify settings only for a specific Route Plan, you need to do it from the tab Route Plans.
