what do they mean?

Hi Bee,

Could you tell me what do these words mean?

board on (bus that she … the last Thursday)

courtesy van (… was ready to transport passengers)

Best regards

To board (on) a bus means to embark on a bus/go aboard a bus.
A courtesy van is a van that is provided out of courtesy, usually free of charge or at a much lower than usual price.

Interesting!

Thanks
