Does anyone know whether the speed cameras on citylink (the Burnley tunnel specifically) are set to book people travelling over the variable speed limit? Or just anyone travelling over 80km/h? Sometimes the speed limit is reduced to 60km/h, and i'd be interested to know whether a hypothetical person would get booked for doing 80km/h when a 60 speed limit applied. Unfortunately there is very little info about this on the web. I would assume that it would be technically possible to implement the variable speed limit on the cameras, but maybe they deliberately leave it at 80 because it would be unreasonable to book people for such a low speed. Any advice appreciated. Thanks.
