The term COMMUTER'S EXPENSE is composed of two crossword solutions: TOLL and FARE. A TOLL is a fee that is charged for the use of a road, bridge, or tunnel. It is usually paid at a TOLL booth or gate. A FARE is the amount of money that a person pays for a ride on public transportation such as a bus, train, or taxi. Commuter's expense is the total cost of a person's transportation to and from work, which includes both the tolls and fares they pay.
