Q: Is it possible to Hitch a Ride after the Truck Full of Manure was played?

…For example: Player A changed the TimeLine. Then Truck Full of Manure is played and Player B’s turn is canceled. Can Player C use Hitch a Ride now?

A: No. Even though Player B’s turn was canceled, they are still “the previous player,” and they did nothing during their turn (except for dealing with all that manure.)
