Quite a lot of our single carriage roads are 80kph too. Mostly regional roads, but theyve started reevaluating national primary and secondary routes too, a large chunk of the N24 that i commute to the office has been cut down to 80 from 100. Very easy get caught out too, as they all have safety camera zones in them too..
