On a trip to one of the islands we met a young North American couple. Should have asked, but we refer to them as the Canadians.
They were parked ready to take into their hotel their luggage. On double yellow lines. Sometimes I feel the advice for travellers is how to drive not how to park. I got to speak to them and advised them to move. So thought I might bring this here and ask for advice about other jurisdictions.
UK: Double yellow lines = do not even think about parking here. Single yellow, or dashed yellow, learn how to decipher the signs.
Not trying to be 'smart', my car has been towed for being in the wrong place where the local council made the restriction borderline impossible to read,and I would not know how to park in the US or Canada.
