With the Hazmat add-on data module installed, hazmat-prohibited and -designated roads will be highlighted in the PC*MILER map window provided this feature is checked in Map Features. The Restrictions legend shows the highlight color for various designations (to show/hide this legend, select the Map tab > Customize > Legends).
TIP: If you don’t want hazmat routing to show up on maps, the highlighting can be hidden from view by turning off the Hazardous Material feature in the Map Features dialog. Select the Map tab > Map Features and uncheck “Hazardous Material”, then click OK to save.
