1)  D.C. cabs may not inquire your destination prior to allowing you inside their cabs.  If they've stopped, you're entitled to your ride.

2)  You have the right to be taken anywhere in the Metro Washington area, including Dulles Airport, Prince Georges, Montgomery, Fairfax, and Arlington Counties, along with the cities of Alexandria and Falls Church.

3)  You are entitled to see the driver's "face card."  You'll want that to report violations.  It is required to be located on the right visor of the front seat (each cab should also have the company name and cab number printed on the door).

4)  You're entitled to see the cab's rate card, and a paper copy of the meter's receipt.
