The “Carpool Angel” option allows you to offer your trips to your passengers for free.
When it is enabled, you do not receive the portion of the fare normally paid by the passenger. Two situations are then possible:
if a regional subsidy is available, you receive it for each passenger you transport;
if no subsidy is available, you receive no payment for the trip.
You can change this option at any time by going to “My account” > “Payment method”, then enabling or disabling “Carpool Angel” according to your preference.
