If you know you are running late or you are going to be absent, you should notify the primary driver. If you are the primary driver, make sure the alternate driver is available. Green Commuter offers an emergency ride home program in the case of an emergency that prevents you from taking the vanpool. If this is the case, please contact Green Commuter. Our app lets you indicate your status with the click of a button. Most vanpool groups make house rules about instances like these. We recommend you talk early and often to establish protocols within your group.
