I have a Zone 1,2,3 & 4 Monthly travelcard at the moment.

How does this work in relation to using Buses. I want to use it for
journeys from Totteridge & Whetstone (LU Zone 4) area and go to High Barnet
area (LU Zone 5) ? Would this be accepted by the oyster reader ?

Any travelcard (for any zone you care to mention) is valid on any bus
displaying the London Buses roundel near the front door.
